    Description

    You will need to download this zipped file and extract to a folder. Again, the file must be extracted to a folder you can find. For me, I like to have a folder simply named GIS and I dump all the files I use in the GIS in this folder.

    Description

    Today, deep neural networks are widely used in many computer vision problems, also for geographic information systems (GIS) data. This type of data is commonly used for urban analyzes and spatial planning. We used orthophotographic images of two residential districts from Kielce, Poland for research including urban sprawl automatic analysis with Transformer-based neural network application.Orthophotomaps were obtained from Kielce GIS portal. Then, the map was manually masked into building and building surroundings classes. Finally, the ortophotomap and corresponding classification mask were simultaneously divided into small tiles. This approach is common in image data preprocessing for machine learning algorithms learning phase. Data contains two original orthophotomaps from Wietrznia and Pod Telegrafem residential districts with corresponding masks and also their tiled version, ready to provide as a training data for machine learning models.Transformed-based neural network has undergone a training process on the Wietrznia dataset, targeted for semantic segmentation of the tiles into buildings and surroundings classes. After that, inference of the models was used to test model's generalization ability on the Pod Telegrafem dataset. The efficiency of the model was satisfying, so it can be used in automatic semantic building segmentation. Then, the process of dividing the images can be reversed and complete classification mask retrieved. This mask can be used for area of the buildings calculations and urban sprawl monitoring, if the research would be repeated for GIS data from wider time horizon.Since the dataset was collected from Kielce GIS portal, as the part of the Polish Main Office of Geodesy and Cartography data resource, it may be used only for non-profit and non-commertial purposes, in private or scientific applications, under the law "Ustawa z dnia 4 lutego 1994 r. o prawie autorskim i prawach pokrewnych (Dz.U. z 2006 r. nr 90 poz 631 z późn. zm.)". There are no other legal or ethical considerations in reuse potential.Data information is presented below.wietrznia_2019.jpg - orthophotomap of Wietrznia districtmodel's - used for training, as an explanatory imagewietrznia_2019.png - classification mask of Wietrznia district - used for model's training, as a target imagewietrznia_2019_validation.jpg - one image from Wietrznia district - used for model's validation during training phasepod_telegrafem_2019.jpg - orthophotomap of Pod Telegrafem district - used for model's evaluation after training phasewietrznia_2019 - folder with wietrznia_2019.jpg (image) and wietrznia_2019.png (annotation) images, divided into 810 tiles (512 x 512 pixels each), tiles with no information were manually removed, so the training data would contain only informative tilestiles presented - used for the model during training (images and annotations for fitting the model to the data)wietrznia_2019_vaidation - folder with wietrznia_2019_validation.jpg image divided into 16 tiles (256 x 256 pixels each) - tiles were presented to the model during training (images for validation model's efficiency); it was not the part of the training datapod_telegrafem_2019 - folder with pod_telegrafem.jpg image divided into 196 tiles (256 x 265 pixels each) - tiles were presented to the model during inference (images for evaluation model's robustness)Dataset was created as described below.Firstly, the orthophotomaps were collected from Kielce Geoportal (https://gis.kielce.eu). Kielce Geoportal offers a .pst recent map from April 2019. It is an orthophotomap with a resolution of 5 x 5 pixels, constructed from a plane flight at 700 meters over ground height, taken with a camera for vertical photos. Downloading was done by WMS in open-source QGIS software (https://www.qgis.org), as a 1:500 scale map, then converted to a 1200 dpi PNG image.Secondly, the map from Wietrznia residential district was manually labelled, also in QGIS, in the same scope, as the orthophotomap. Annotation based on land cover map information was also obtained from Kielce Geoportal. There are two classes - residential building and surrounding. Second map, from Pod Telegrafem district was not annotated, since it was used in the testing phase and imitates situation, where there is no annotation for the new data presented to the model.Next, the images was converted to an RGB JPG images, and the annotation map was converted to 8-bit GRAY PNG image.Finally, Wietrznia data files were tiled to 512 x 512 pixels tiles, in Python PIL library. Tiles with no information or a relatively small amount of information (only white background or mostly white background) were manually removed. So, from the 29113 x 15938 pixels orthophotomap, only 810 tiles with corresponding annotations were left, ready to train the machine learning model for the semantic segmentation task. Pod Telegrafem orthophotomap was tiled with no manual removing, so from the 7168 x 7168 pixels ortophotomap were created 197 tiles with 256 x 256 pixels resolution. There was also image of one residential building, used for model's validation during training phase, it was not the part of the training data, but was a part of Wietrznia residential area. It was 2048 x 2048 pixel ortophotomap, tiled to 16 tiles 256 x 265 pixels each.

    Description

    In 2016-2017 zijn alle hunebedden van Nederland door het Groninger Instituut voor Archeologie opnieuw in kaart gebracht als 3D modellen (op basis van fotogrammetrie) met georeferentie (DGPS). Hieruit is een complete dataset met geografische informatie verkregen van elk van de 54 nog bestaande Nederlandse hunebedden (excl. Delfzijl). Van elk hunebed is een digital elevation model en orthofoto (loodrecht bovenaanzicht) beschikbaar in zeer hoge resolutie (DEM van 30 tot 100 MP, luchtfoto tot 400 MP) in coördinaten van het rijksdriehoeksstelsel (RD New - ESPG: 28992). Ook is van elk hunebed een gecorrigeerde positie (punt) en een digitale lijntekening (dissolved polyline) gemaakt in navolging van het werk van Van Giffen en zijn team in 1918. De dataset bevat tevens een QGIS file waarin de data is verzameld. Vier ZIP-files in deze dataset bevatten: Basisdata.zip (folder) - vectordata, punt, lijn en polygoon, waaronder een tabel met puntlocaties van alle hunebedden en basis metadata.

    Description

    This dataset is a compilation of geographic rasters from multiple environmental data sources. It aims at making the life of SDM users easier. All rasters cover the metropolitan French territory, but have varying resolutions and projections. Each directory inside the main directory "0_mydata" contain a single environmental raster. Punctual extraction of raster values can be easily done for large sets of WGS84-(longitude,latitude) points coordinates and for multiple rasters at the same time through the R function get_variables of script _functions.R from Github repository: https://github.com/ChrisBotella/SamplingEffort. All data sources are accessible on the web and free of use, at least for scientific purpose. They have various conditions of citations. Anyone diffusing a work using the present data must reference along with the present DOI, the original source data employed. Those source data are described in the paragraphs below. We provide the articles to cite, when required, and webpages for access.

    Pedologic Descriptors of the ESDB v2: 1 km × 1 km Raster Library : The library contains multiple soil pedology (physico-chemical properties of the soil) descriptors raster layers covering Eurasia at a resolution of 1 km. We selected 11 descriptors from the library. They come from the PTRDB. The PTRDB variables have been directly derived from the initial soil classification of the Soil Geographical Data Base of Europe (SGDBE) using expert rules. For more details, see [1, 2] and [3]. The data is maintained and distributed freely for scientific use by the European Soil Data Centre (ESDAC) at http://eusoils.jrc.ec.europa.eu/content/european-soil-databasev2-raster. The 11 rasters are in the directories "awc_top", "bs_top", "cec_top", "dimp", "crusting", "erodi", "dgh", "text", "vs", "oc_top", "pd_top".

    Corine Land Cover 2012, Version 18.5.1, 12/2016 : It is a raster layer describing soil occupation with 48 categories across Europe (25 countries) at a resolution of 100 m. This data base of the European Union is freely accessible online for all use at http://land.copernicus.eu/pan-european/corine-land-cover/clc-2012. The raster of this variable is in the directory "clc".

    Hydrographic Descriptor of BD Carthage v3: BD Carthage is a spatial relational database holding many informations on the structure and nature of the french metropolitan hydrological network. For the purpose of plants ecological niche, we focus on the geometric segments representing watercourses, and polygons representing hydrographic fresh surfaces. The data has been produced by the Institut National de l’information Géographique et forestière (IGN) from an interpretation of the BD Ortho IGN. It is maintained by the SANDRE under free license for non-profit use and downloadable at:
    http://services.sandre.eaufrance.fr/telechargement/geo/ETH/BDCarthage/FX
    From this shapefile, we derived a raster containing the binary value raster proxi_eau_fast, i.e. proximity to fresh water, all over France.We used qgis to rasterize to a 12.5m resolution, with a buffer of 50m, the shapefile COURS_D_EAU.shp on
    one hand, and the polygons of SURFACES_HYDROGRAPHIQUES.shp with attribute NATURE=“Eau douce
    permanente” on the other hand.We then created the maximum raster of the previous ones (So the value of 1 correspond to an approximate distance of less than 50m to a watercourse or hydrographic surface of fresh water). The raster is in the directory named "proxi_eau_fast".

    USGS Digital Elevation Data : The Shuttle Radar Topography Mission achieved in 2010 by Endeavour shuttle measured elevation at three arc second resolution over most of the earth surface. Raw measures have been post-processed by NASA and NGA in order to correct detection anomalies. The data is available from the U.S. Geological Survey, and downloadable on the Earthexplorer (https://earthexplorer.usgs.gov/). One may refer to https://www.usgs.gov/centers/eros/science/usgs-eros-archive-digital-elevation-shuttle-radar-topography-mission-srtm-void?qt-science_center_objects=0#qt-science_center_objects for more informations. the elevation raster is in the directory named "alti".

    Potential Evapotranspiration of CGIAR-CSI ETP : The CGIAR-CSI distributes this worldwide monthly potential-evapotranspiration raster data. It is pulled from a model developed by Antonio Trabucco [4, 5]. Those are estimated by the Hargreaves formula, using mean monthly surface temperatures and standard deviation from WorldClim 1:4 (http://www.worldclim. org/), and radiation on top of atmosphere. The raster is at a 1km resolution, and is
    freely downloadable for a nonprofit use at: http://www.cgiar-csi.org/data/global-aridity-and-pet-database#description. This raster is in the directory "etp".

    Bioclimatic Descriptors of Chelsea Climate Data 1.1: Those are raster data with worldwide coverage and 1 km resolution. A mechanistical climatic model is used to make spatial predictions of monthly mean-max-min temperatures, mean precipitations and 19 bioclimatic variables, which are downscaled with statistical models integrating historical measures of meteorologic stations from 1979 to today. The exact method is explained in the reference papers [6] and [7]. The data is under Creative Commons Attribution 4.0 International License and downloadable at (http://chelsa-climate.org/downloads/). The 19 bioclimatic rasters are located in the directories named "chbio_X".

    ROUTE500 1.1: This database register classified road linkages between cities (highways, national roads, and departmental roads) in France in shapefile format, representing approxi-mately 500,000 km of roads. It is produced under free license (all uses) by the IGN. Data are available online at http://osm13.openstreetmap.fr/~cquest/route500/. For deriving the variable “droute_fast”, the distance to the main roads networks, we computed with qGis the distance raster to the union of all elements of the shapefile ROUTES.shp (segments).

    Description

    The data are derived from interpretation of seismic reflection profiles within the offshore Corinth Rift, Greece (the Gulf of Corinth) integrated with IODP scientific ocean drilling borehole data from IODP Expedition 381 (McNeill et al., 2019a, 2019b). The data include rift fault coordinate (location, geometry) information and slip rate and extension rate information for the major faults. Seismic reflection data were published in Taylor et al. (2011) and in Nixon et al. (2016). Preliminary fault interpretations and rate data, prior to IODP drilling, were published in Nixon et al. (2016). Details of datasets: The data can be viewed in GIS software (ArcGIS, QGIS) or the Excel and .dbf files can be used for viewing of rate data and import of fault coordinates into other software. The 4 folders are for different time periods with shape files for the N-Dipping and S-Dipping Faults in the offshore Corinth Rift and respective slip and extension (horizontal) rates. The shapefiles are digitised fault traces for the basement offsetting faults, picked from the Multichannel Seismic Data collected by the R/V Maurice Ewing. Fault traces are segmented and each segment has an average throw (vertical) rate (Tavg) in mm/yr. The rates for the segments are averages based on measurements at the ends of each segment. The major fault trace segments also have slip-rates (slip_rate) and extension-rates (ext_rate or extension_) in mm/yr. All rates as well as the names for major faults can be located in the attribute table of the shape files along with X- and Y-coordinates. The coordinate system is WGS84 UTM Zone 34N. The shape files can be loaded into a GIS (ArcGIS, QGIS etc.) allowing mapping and visualization of the fault traces and their activity rates. In addition, the attribute tables are .dbf files found within each folder. These have also been provided as .xlsx (Excel) files which include the fault coordinate information, and slip rates and extension rates along the major faults.

Because R cannot produce the 3D map. Therefore, the "Qgis" folder comprises the QGIS files for visualising and mapping the produced GIS data. We used the Qgis2threejs plugin to visualise the 3D scene.

    Description

    The Science Case in the Caribbean region presents records on landslides, precipitation, maps used as inputs of hazard models and drone imagery over the region of interest.
    For the Carribean study-case, an analysis of open and proprietary satellite based dataset was used to facilitate the setup and evaluation of physically-based multi-hazard models. These allow for qualification and quantification of spatio-temporal multi-hazard patterns. These form a crucial input into the general hazard and risk assessment workflow.

    Presented here are the datasets employed for Case Study 4 in Deliverable D3.1 with a short description, produced and saved within the following folders:

    Dominica_landslide: the landslides datasets mapped by ITC using high-resolution satellite imagery. It is intended to calibrate and validate the flood and landslide modelling. The folder contains four shapefiles:

    · Landslide_Part.shp - Shapefile containing landslide extent, flash flood extents, and their attributes.

    · Cloud.shp – Shapefile represents the cloud-filled areas in the satellite imagery where no mapping was possible.

    · The other two shapefiles are self-explanatory.

    GPM_Maria: NASA Global Precipitation Mission (GPM) precipitation maps processed for model input in LISEM. GPM is a hybrid fusion with satellite datasets for precipitation estimates. Mean as input data to represent precipitation in the landslide and flood modelling.

    Maps_Models_Input : Soil and land use and channels, lots of custom work, SOILGRIDS, and SPOT image classification; all the datasets are ready for model input for OpenLISEM and LISEM Hazard or FastFlood. The dataset is meant to calibrate and validate the flood and landslide modelling.

    The raster files are either in Geotiff format or PCraster map format. Both can be opened by GIS systems such as GDAL or QGIS. The projection of each file is in UTM20N.

    Some key files are:

    • dem.map -elevation model, the height of the landscape in meters above sea level.
    • lai.map - leaf area index, estimated using empirical relationships based on NDVI (Normalized Difference Vegetation Index)). The source data to calculate NDVI is Sentinel-2.
    • KSat.map - Saturated hydraulic conductivity of the soil, estimated based on a combination of SOILGRIDS soil texture, Saxton et al. (2006) Pedotransfer functions, and a national soil map for Dominica.
    • clay.map - Clay texture fraction, SoilGrids resampling
    • silt.map - Silt texture fraction, SoilGrids resampling
    • sand.map - Sand texture fraction, SoilGrids resampling
    • cover.map - Vegetation cover as a fraction, estimated using linear correlation with NDVI.
    • lu_new.map - Spot satellite image classification at 10 meters resolution for predominant land use types.
    • n.map - Mannings surface roughness coefficient, specific value based on the land use type.
    • ndvi.map - Normalized Differential Vegetation Index, based on Sentinel-2 images in summer.
    • ldd.map - Drainage network map for the island, which can be used for flow accumulation and streamflow detection
    • catchments.map - Catchment ID's based on the ldd.map drainage network.
    • Channelldd.map - Channel-only drainage network map, calibrated manually to have all channels on the island represented correctly.
    • Soildepth - Soil depth in meters, based on a physically-based soil depth model in meters and observational data obtained from landslide-sites during fieldwork in 2018.
    • Slope.map - Slope map in gradient of the elevation model (m/m) in the steepest direction

    StakeholderQuestionnaire_Survey_ITC: The stakeholder questionnaires particularly relating to the tools developed partly by this project on rapid hazard modelling. Stakeholder Engagement survey and Stakeholder Survey Results prepared and implemented by Sruthie Rajendran as part of her MSc Thesis Twin Framework For Decision Support In Flood Risk Management supervised by Dr. M.N. Koeva (Mila) and Dr. B. van den Bout (Bastian) submitted in July 2024.

    ·Drone_Images_ 2024: Images captured using a DJI drone of part of the Study area in February 2024. The file comprises three different regions: Coulibistrie, Pichelin and Point Michel. The 3D models for Coulibistrie were generated from the nadir drone images using photogrammetric techniques employed by the software Pix4D. The image Coordinate System is WGS 84 (EGM 96 Geoid0), but the Output Coordinate System of the 3D model is WGS 84 / UTM zone 20N (EGM 96 Geoid). The other two folders contain only the drone images captured for that particular region's Pichelin and Point Michel. The dataset is used with other datasets to prepare and create the digital twin framework tailored for flood risk management in the study area.

    Description

    Datasets associated to the report titled 'Shore Channel Sedimentary Processes, Passability by Migrating Fish and Habitat Suitability'.Summary:The current study consists of three parts (1) an analysis of the sedimentary processes in the shore channels along the longitudinal dams in the River Waal (LTDs), (2) an assessment of the upstream passability of the shore channel inflows by migratory fish species, and (3) an analysis of the habitat suitability of the shore channels for fish, macroinvertebrates and macrophytes. For the first analysis, light detection and ranging (LiDAR), multibeam echosounder (MBES), and aerial photographs datasets were used to examine geomorphological processes (erosion and deposition), calculate the retreat rate of eroding banklines, and analyze the development of shoreline length over time in the mesohabitats of shore channels and reference study areas. The second part of the analysis focused on the use of acoustic doppler current profiler (ADCP) datasets to produce 3D lattices of flow velocity in the inflow openings of shore channels at high river discharge. This was combined with data and linear relations from scientific literature on the swimming performance of relevant migratory fish species in the Rhine. The third part consisted in assessing the habitat suitability of the shore channel with the data on substrate, water depth and flow velocity collected in 2020. This was done using the species sensitivity distributions (SSDs) available in the scientific literature for fish, macroinvertebrates and macrophytes occurring in the Rhine. The produced substrate maps of May 2020 were compared with substrate maps of April 2019. The main conclusions of the studies are:1. The shore channels of the LTDs showed a pattern of aggradation of the bed towards the dams and degradation towards the bank. From 2015 to 2019 there was net sediment loss in all three shore channels with Wamel having the least and Dreumel themost. Compared to the groyne field areas the Wamel shore channel is almost stable. The eroding banklines had a retreat rate of 1.6 m/y and the sand dominated mesohabitats in the shore channels had longer shorelines.2. Larger juveniles (TL = 70 mm) of fish species occurring in the Rhine passed some of the study sites during high discharge conditions and performed better during average discharge conditions. Adult fish had no problems passing the inflow opening, with the exception of Gasterosteus aculeatus aculeatus. Fish species were able to pass all 10 3D lattices produced once they reached a minimum TL of about 165 mm. The inflow of the Ophemert shore channel was the least passable of the LTDs.3. The habitats in the center and bank lines of the shore channels were most suitable for all species groups studied because of substrate heterogeneity, shallow water and relatively low flow velocities. All three shore channels had more mixed substrate typein 2020 than in 2019.The dataset includes:1. Sedimentary Processes.zip includes:a.

    Description

    Source:

    This dataset supports the publication: Martin, H.K., Edmonds, D.A., Yanites, B.J. & Niemi, N.A. (2024) Quantifying landscape change following catastrophic dam failures in Edenville and Sanford, Michigan, USA. Earth Surf. Process. Landforms, Available from: https://doi.org/10.1002/esp.5855. All of the details about how these data were collected and processed are provided in that paper, particularly in the Supporting Information.

    Brief Summary:

    On May 19, 2020, the Edenville and Sanford dams near Midland, Michigan, USA failed as the result of significant rainfall over the preceding two days. We analyzed the geomorphic impacts of these failures using a pre-failure airborne lidar dataset and three UAV-based lidar surveys collected two weeks ("2020-06"), three months ("2020-08)", and eleven months ("2021-04") post-failure. The pre-failure airborne lidar dataset was merged from two datasets hosted on OpenTopography as part of the USGS 3DEP project. These are linked to in the Supporting Information document for the above manuscript. This upload contains data from the three UAV-based surveys we collected.

    Structure/Contents:

    The .zip file is structured first by dates, with each folder corresponding to one of our three field campaigns.
    Within each date folder, there are two folders: one for data collected at Edenville and another for data collected at Sanford.
    Within each location folder, there are two items.
    1. One is a .las file that contains the ground-classified point cloud data. For Edenville, these point clouds are merged from data collected from multiple launch locations. The point cloud file has had corrections applied to it. It corresponds to the output that results from the Supporting Information through the end of section 2.3: Lidar processing. These files can be opened and worked with using most-any software that handles point clouds; users preferring free and open source software could consider using CloudCompare [https://cloudcompare.org/].
    2. The second is a folder containing DEMs, which are raster images derived from the point cloud data in the corresponding location folder. Each pixel contains the elevation of that area in meters above sea level. Two copies are provided: one with the pixel size set to 50 cm by 50 cm, and the other set to 1 m by 1 m. These were created by constructing a triangular lattice between ground-classified points in the point cloud and then sampling the mesh. These maps are provided for convenience for users who prefer to work with raster data over point clouds or would otherwise prefer not to have to rasterize point cloud data themselves. These files can be opened and worked with using any GIS software; users preferring free and open source software could consider using QGIS [https://www.qgis.org/en/site/]. The CRS is NAD83 UTM Zone 16N.

    Description

    Overview

    3DHD CityScenes is the most comprehensive, large-scale high-definition (HD) map dataset to date, annotated in the three spatial dimensions of globally referenced, high-density LiDAR point clouds collected in urban domains. Our HD map covers 127 km of road sections of the inner city of Hamburg, Germany including 467 km of individual lanes. In total, our map comprises 266,762 individual items.

    Our corresponding paper (published at ITSC 2022) is available here. Further, we have applied 3DHD CityScenes to map deviation detection here.

    Moreover, we release code to facilitate the application of our dataset and the reproducibility of our research. Specifically, our 3DHD_DevKit comprises:

    Python tools to read, generate, and visualize the dataset,

    3DHDNet deep learning pipeline (training, inference, evaluation) for map deviation detection and 3D object detection.

    The DevKit is available here:

    https://github.com/volkswagen/3DHD_devkit.

    The dataset and DevKit have been created by Christopher Plachetka as project lead during his PhD period at Volkswagen Group, Germany.

    When using our dataset, you are welcome to cite:

    Niels Maier: Measurement campaign for data collection and data preparation

    The European large-scale project Hi-Drive (www.Hi-Drive.eu) supports the publication of 3DHD CityScenes and encourages the general publication of information and databases facilitating the development of automated driving technologies.

    The Dataset

    After downloading, the 3DHD_CityScenes folder provides five subdirectories, which are explained briefly in the following.

    1. Dataset

    This directory contains the training, validation, and test set definition (train.json, val.json, test.json) used in our publications. Respective files contain samples that define a geolocation and the orientation of the ego vehicle in global coordinates on the map.

    During dataset generation (done by our DevKit), samples are used to take crops from the larger point cloud. Also, map elements in reach of a sample are collected. Both modalities can then be used, e.g., as input to a neural network such as our 3DHDNet.

    To read any JSON-encoded data provided by 3DHD CityScenes in Python, you can use the following code snipped as an example.

    import json

    json_path = r"E:\3DHD_CityScenes\Dataset\train.json" with open(json_path) as jf: data = json.load(jf) print(data)

    1. HD_Map

    Map items are stored as lists of items in JSON format. In particular, we provide:

    traffic signs,

    traffic lights,

    pole-like objects,

    construction site locations,

    construction site obstacles (point-like such as cones, and line-like such as fences),

    line-shaped markings (solid, dashed, etc.),

    polygon-shaped markings (arrows, stop lines, symbols, etc.),

    lanes (ordinary and temporary),

    relations between elements (only for construction sites, e.g., sign to lane association).

    1. HD_Map_MetaData

    Our high-density point cloud used as basis for annotating the HD map is split in 648 tiles. This directory contains the geolocation for each tile as polygon on the map. You can view the respective tile definition using QGIS. Alternatively, we also provide respective polygons as lists of UTM coordinates in JSON.

    Files with the ending .dbf, .prj, .qpj, .shp, and .shx belong to the tile definition as “shape file” (commonly used in geodesy) that can be viewed using QGIS. The JSON file contains the same information provided in a different format used in our Python API.

    1. HD_PointCloud_Tiles

    The high-density point cloud tiles are provided in global UTM32N coordinates and are encoded in a proprietary binary format. The first 4 bytes (integer) encode the number of points contained in that file. Subsequently, all point cloud values are provided as arrays. First all x-values, then all y-values, and so on. Specifically, the arrays are encoded as follows.

    x-coordinates: 4 byte integer

    y-coordinates: 4 byte integer

    z-coordinates: 4 byte integer

    intensity of reflected beams: 2 byte unsigned integer

    ground classification flag: 1 byte unsigned integer

    After reading, respective values have to be unnormalized. As an example, you can use the following code snipped to read the point cloud data. For visualization, you can use the pptk package, for instance.

    import numpy as np import pptk

    file_path = r"E:\3DHD_CityScenes\HD_PointCloud_Tiles\HH_001.bin" pc_dict = {} key_list = ['x', 'y', 'z', 'intensity', 'is_ground'] type_list = ['

    Description

    This zip file contains thirteen thermal orthomosaics depicting an aerial view of eight flying-fox (Pteropus spp.) colonies throughout the Greater Sydney region, Australia. The zip file contains thirteen folders, each containing the georeferenced thermal orthomosaic depicting the flying-fox colony, as well as four semi-automatically classified image products, classifying the thermal image into two classes: flying-fox, and background. The number of image segments classified as flying-fox were counted to give an estimate of the number of flying-foxes in the original thermal orthomosaic. Each thermal orthomosaic was classified using (1) a Computer Vision pipeline (denoted CV), (2) Object-based image segmentation and Random Forest classification (denoted RF), (3) Object-based image segmentation and Support Vector Machines classification (denoted SVM) and (4) Object-based image segmentation and Maximum Likelihood classification (denoted ML).Each folder is named with the colony location and the date of image capture, for example ‘CamelliaGardens200220’ contains an orthomosaic and classified image products depicting the Camellia Gardens flying-fox colony on the 20th of February 2020. Within each folder, images are named with their type, colony location and the date of image capture. For example, the image name ‘CVCamelliaGardens200220’ is the Computer vision pipeline classified orthomosaic of the Camellia Gardens colony on the 20th of February 2020.This file also contains a fourteenth folder entitled 'Orthomosaic precision study' which contains orthomosaics and other material pertaining to the precision assessment presented in this paper.All thermal orthomosaics contained in this file are georeferenced .tif files and can be viewed in Geographical Information Systems software such as ArcGIS, QGIS or R. All classified image products contained in this file are .tif files and can be viewed in Geographical Information Systems software such as ArcGIS, QGIS or R. All files can be viewed in any .tif image viewing software.For all colonies depicted here, landowner permission was obtained prior to drone flights.

Description

You will need to download this zipped file and extract to a folder. Again, the file must be extracted to a folder you can find. For me, I like to have a folder simply named GIS and I dump all the files I use in the GIS in this folder.
