    Description

    This data package contains identifiers, metadata, and a map of the locations where field measurements have been conducted at the East River Community Observatory located in the Upper Colorado River Basin, United States. The East River is the primary field site of the Watershed Function Scientific Focus Area (WFSFA) and the Rocky Mountain Biological Laboratory. Researchers from over 30 institutions generate highly diverse hydrological, biogeochemical, climate, vegetation, geological, remote sensing, and model data at the East River in collaboration with the WFSFA. Thus, the purpose of this data package is to maintain an inventory of the field locations and instrumentation to provide information on the field activities in the East River and coordinate data collected across different locations, researchers, and institutions. The data package contains (1) a README file with information on the various files, (2) three csv files describing the metadata collected for each surface point location, plot and region registered with the WF SFA, (3) csv files with metadata and contact information for each surface point location registered with the WF SFA, (4) a csv file with with metadata and contact information for plots, (5) a csv file with metadata for geographic regions and sub-regions within the watershed, (6) a compiled xlsx file with all the data and metadata which can be opened in Microsoft Excel, and (7) a kmz map of the locations plotted in the watershed which can be opened in Google Earth. Persistent location identifiers are determined by the WFSFA data management team and are used to track data and samples across locations. Researchers interested in having their East River measurement locations added in this list should reach out to the WFSFA data management team at wfsfa-data@googlegroups.com. Acknowledgements: Please cite this dataset if using any of the location metadata in other publications or derived products. If using the location metadata for the NEON hyperspectral campaign, additionally cite Chadwick et al. (2020). doi:10.15485/1618130.

    Description

    The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The primary legal divisions of most states are termed counties. In Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and for the unorganized area, census areas. The latter are delineated cooperatively for statistical purposes by the State of Alaska and the Census Bureau. In four states (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their states. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation. The District of Columbia and Guam have no primary divisions, and each area is considered an equivalent entity for purposes of data presentation. The Census Bureau treats the following entities as equivalents of counties for purposes of data presentation: Municipios in Puerto Rico, Districts and Islands in American Samoa, Municipalities in the Commonwealth of the Northern Mariana Islands, and Islands in the U.S. Virgin Islands. The entire area of the United States, Puerto Rico, and the Island Areas is covered by counties or equivalent entities. The boundaries for counties and equivalent entities are as of January 1, 2017, primarily as reported through the Census Bureau's Boundary and Annexation Survey (BAS).

    Description

    The dataset is outcome of a paper "Floating Car Data Map-matching Utilizing the Dijkstra Algorithm" accepted for 3rd International Conference on Data Management, Analytics & Innovation held in Kuala Lumpur, Malaysia in 2019.

    The floating car data (FCD representing movement of cars with their position in time) is produced by the traffic simulator software (further referred to as Simulator) published in [1] and can be used as an input for data processing and benchmarking. The dataset contains FCD of various quality levels based on the routing graph of the Czech Republic derived from Open Street Map openstreetmap.org.

    Should the dataset be exploited in scientific or other way, any acknowledgement or references to our paper [1] and dataset are welcomed and highly appreciated.

    Archive contents

    The archive contains following folders.

    city_oneway and city_roadtrip - FCD from the city of Brno, Czech Republic where FCD is based on Origin-Destination in case of oneway and Origin-Destination-Origin in case of a road trip

    intercity_oneway and intercity_roadtrip - FCD from cities of Brno, Ostrava, Olomouc and Zlin, all Czech Republic where FCD is based on Origin-Destination in case of oneway and Origin-Destination-Origin in case of a road trip

    Content explanation

    All four of mentioned folders contain raw FCD as they come from our Simulator, post-processed FCD enriching Simulator FCD, and obfuscated raw FCD (of both low and high obfuscation level). In the both obfuscated data sets, each measured point was moved in a random direction a number of meters given by drawing a number from a Gaussian distribution. We utilized two Gaussian distributions, one for the roads outside the city (N(0,10) for the lower and N(0,20) for the higher obfuscation level) and one for the roads inside the city (N(0,15) and N(0,30) respectively). Then some predefined number of randomly chosen points were removed (3% in our case). This approach should roughly represent real conditions encountered by FCD data as described by El Abbous and Samanta [2].

    In case of post-processed road trip data, there is one extra dataset with "cache" suffix representing the very same dataset limited to a 5-minute session memoization. This folder also contains a picture of processed FCD represented on a map.

    Description

    Summary:

    The files contained herein represent green roof footprints in NYC visible in 2016 high-resolution orthoimagery of NYC (described at https://github.com/CityOfNewYork/nyc-geo-metadata/blob/master/Metadata/Metadata_AerialImagery.md). Previously documented green roofs were aggregated in 2016 from multiple data sources including from NYC Department of Parks and Recreation and the NYC Department of Environmental Protection, greenroofs.com, and greenhomenyc.org. Footprints of the green roof surfaces were manually digitized based on the 2016 imagery, and a sample of other roof types were digitized to create a set of training data for classification of the imagery. A Mahalanobis distance classifier was employed in Google Earth Engine, and results were manually corrected, removing non-green roofs that were classified and adjusting shape/outlines of the classified green roofs to remove significant errors based on visual inspection with imagery across multiple time points. Ultimately, these initial data represent an estimate of where green roofs existed as of the imagery used, in 2016.

    These data are associated with an existing GitHub Repository, https://github.com/tnc-ny-science/NYC_GreenRoofMapping, and as needed and appropriate pending future work, versioned updates will be released here.

Any sale, distribution, loan, or offering for use of these digital data, in whole or in part, is prohibited without the approval of The Nature Conservancy and co-authors. The use of these data to produce other GIS products and services with the intent to sell for a profit is prohibited without the written consent of The Nature Conservancy and co-authors. All parties receiving these data must be informed of these restrictions. Authors of this work shall be acknowledged as data contributors to any reports or other products derived from these data.

    Associated Files:

    As of this release, the specific files included here are:

    • GreenRoofData2016_20180917.geojson is in the human-readable, GeoJSON format, in geographic coordinates (Lat/Long, WGS84; EPSG 4263).
    • GreenRoofData2016_20180917.gpkg is in the GeoPackage format, which is an Open Standard readable by most GIS software including Esri products (tested on ArcMap 10.3.1 and multiple versions of QGIS). This dataset is in the New York State Plan Coordinate System (units in feet) for the Long Island Zone, North American Datum 1983, EPSG 2263.
    • GreenRoofData2016_20180917_Shapefile.zip is a zipped folder containing a Shapefile and associated files. Please note that some field names were truncated due to limitations of Shapefiles, but columns are in the same order as for other files and in the same order as listed below. This dataset is in the New York State Plan Coordinate System (units in feet) for the Long Island Zone, North American Datum 1983, EPSG 2263.
    • GreenRoofData2016_20180917.csv is a comma-separated values file (CSV) with coordinates for centroids for the green roofs stored in the table itself. This allows for easily opening the data in a tool like spreadsheet software (e.g., Microsoft Excel) or a text editor.

    Column Information for the datasets:

    Some, but not all fields were joined to the green roof footprint data based on building footprint and tax lot data; those datasets are embedded as hyperlinks below.

    • fid - Unique identifier
    • bin - NYC Building ID Number based on overlap between green roof areas and a building footprint dataset for NYC from August, 2017. (Newer building footprint datasets do not have linkages to the tax lot identifier (bbl), thus this older dataset was used). The most current building footprint dataset should be available at: https://data.cityofnewyork.us/Housing-Development/Building-Footprints/nqwf-w8eh. Associated metadata for fields from that dataset are available at https://github.com/CityOfNewYork/nyc-geo-metadata/blob/master/Metadata/Metadata_BuildingFootprints.md.
    • bbl - Boro Block and Lot number as a single string. This field is a tax lot identifier for NYC, which can be tied to the Digital Tax Map (http://gis.nyc.gov/taxmap/map.htm) and PLUTO/MapPLUTO (https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page). Metadata for fields pulled from PLUTO/MapPLUTO can be found in the PLUTO Data Dictionary found on the aforementioned page. All joins to this bbl were based on MapPLUTO version 18v1.
    • gr_area - Total area of the footprint of the green roof as per this data layer, in square feet, calculated using the projected coordinate system (EPSG 2263).
    • bldg_area - Total area of the footprint of the associated building, in square feet, calculated using the projected coordinate system (EPSG 2263).
    • prop_gr - Proportion of the building covered by green roof according to this layer (gr_area/bldg_area).
    • cnstrct_yr - Year the building was constructed, pulled from the Building Footprint data.
    • doitt_id - An identifier for the building assigned by the NYC Dept. of Information Technology and Telecommunications, pulled from the Building Footprint Data.
    • heightroof - Height of the roof of the associated building, pulled from the Building Footprint Data.
    • feat_code - Code describing the type of building, pulled from the Building Footprint Data.
    • groundelev - Lowest elevation at the building level, pulled from the Building Footprint Data.
    • qa - Flag indicating a positive QA/QC check (using multiple types of imagery); all data in this dataset should have 'Good'
    • notes - Any notes about the green roof taken during visual inspection of imagery; for example, it was noted if the green roof appeared to be missing in newer imagery, or if there were parts of the roof for which it was unclear whether there was green roof area or potted plants.
    • classified - Flag indicating whether the green roof was detected image classification. (1 for yes, 0 for no)
    • digitized - Flag indicating whether the green roof was digitized prior to image classification and used as training data. (1 for yes, 0 for no)
    • newlyadded - Flag indicating whether the green roof was detected solely by visual inspection after the image classification and added. (1 for yes, 0 for no)
    • original_source - Indication of what the original data source was, whether a specific website, agency such as NYC Dept. of Parks and Recreation (DPR), or NYC Dept. of Environmental Protection (DEP). Multiple sources are separated by a slash.
    • address - Address based on MapPLUTO, joined to the dataset based on bbl.
    • borough - Borough abbreviation pulled from MapPLUTO.
    • ownertype - Owner type field pulled from MapPLUTO.
    • zonedist1 - Zoning District 1 type pulled from MapPLUTO.
    • spdist1 - Special District 1 pulled from MapPLUTO.
    • bbl_fixed - Flag to indicate whether bbl was manually fixed. Since tax lot data may have changed slightly since the release of the building footprint data used in this work, a small percentage of bbl codes had to be manually updated based on overlay between the green roof footprint and the MapPLUTO data, when no join was feasible based on the bbl code from the building footprint data. (1 for yes, 0 for no)

    For GreenRoofData2016_20180917.csv there are two additional columns, representing the coordinates of centroids in geographic coordinates (Lat/Long, WGS84; EPSG 4263):

    • xcoord - Longitude in decimal degrees.
    • ycoord - Latitude in decimal degrees.

    Description

    Microdata of the ANTIELAB Research Data Archive - Mobilization Map

    Field definition (event.csv):

    event-id: an unique event identifier date: date of the event time: hour of a day of the event link: url link(s) to the call for action posts on the Telegram channel type: type of the event district: one of the 18 Hong Kong districts (in Chinese) location1-13: specific locations identified in the post(s) (in Chinese)

    The shape file contains the WSG84 coordinates of each of the identified locations of every event. You can look up the geographical coordinates of the events by matching the field ‘event_id’ in the shape file with that in the CSV file. The coordinates are provided by Google’s Geocoding API and Place API.

    Description

    The dataset contains plant species occurrence records in the upper to mid Tana River Basin, digitized from preserved specimens at the East African Herbarium (EA), Nairobi. The dataset is a subset of the EA BRAHMS database generated over several years through various projects and day-to-day digitization efforts. Specimen records from the Tana River Basin were extracted from the EA BRAHMS dataset then cleaned and formatted in Darwin Core Standard. Data cleaning was done using Open Refine Software as well as the GPS Visualizer tool to generate altitude values from coordinates. Elevation data from GPS Visualizer is controlled from a variety of reputable sources including SRTM, ASTER, USGS and Google Maps. Other cleaning tasks included correcting spellings, filling in missing data, checking the taxonomy, dates, and subnational administrative areas. Records without coordinates were georeferenced using GEOLocate, Google Maps, and Gazetteers. The field altitude (m) was automatically generated from GPS Visualizer (https://www.gpsvisualizer.com/elevation) to generate missing elevation values. The process involved uploading a CSV format file with latitude and longitude values to the website which then sampled these coordinates against inbuilt elevation profile files (Digital Elevation Models) to give altitude values at specified coordinates. Most coordinates were also retrieved from gazetteers as they are legacy data.

    abundance.invertebrates.sweep - number of invertebrates captured by sweep nets. An invertebrate was defined as lacking a structural backbone.

    Methods

    Data was collected across four observers and later compiled into a single digital document. Data collected approximately from 15:00 to 17:00 on October 17, 2016 at the York University's designated "The Pond Area" and "impermeable ground Area". Weather conditions was foggy , mild temperatures and slightly breeze. The process of collecting data was repeated twice. Once by The Pond Area at York U, and then again at the Impermeable Area. All abundances were counted and were clearly visible. Two transects were combined to encompass 50 meters long . Most collection of data used the transects as a reference point. 25 quadrats were placed in each habitat, distanced apart by 2 meters from the last, while also alternating left and right of the transect. An observer would count the abundance of native and exotic plants in the quadrat, as well as the number of flower heads.

    An observer would walk along the transect. Every 2 meters, they would approximate the abundance of trees and flowers, as well as canopy coverage and vegetative ground coverage. Coverages were approximated as percentages.

    The abundance of verterbrates, invertebrates, number of vertebrate species, and abundance of humans were measured along the transect. Vertebrate information was collected on a 50m radius from the transect, and invertebrate information was collected on a 5m radius. Observances were made in a counter-clockwise direction around the transect for 15 minutes. To visualize a 50m observation range, the observer referred to the transect laid out. To cover a 5m observation range, the observer took 5 large steps. Any vertebrate that was more than 0.5m above the observer's view was not collected. Humans in vehicles were not included in the data, nor were humans recounted if they made a double appearance. The humans were counted as long as they were within observation range regardless if they were just passing by.

    An observer placed six pan traps in alternating color order. They were placed at 14:52 at The Pond Area, picked up at 16:20, while placed at 16:25 on the impermeable Area, and picked up at 17:09). The pan traps were distanced along the transect, 3 meters apart from the last. 10 sweep nets traveled 50m along the transect to capture invertebrates. 5 sweep nets on each side of the transect.

    Hypothesis: As the amount of plants increase, the amount of invertebrates will increase as the plants provide them with resources.
    Prediction: 1. Near pond will have a greater abundance of invertebrates than the impermeable ground because there will be a higher abundance of plants resulting in more resources.

    1. As the impermeable ground lacked plants, there would be no observable ground invertebrates.

    Additional Information:

    Hypothesis and Predictions:

    A. It is hypothesized that there will be a negative relationship between the 2 variables, (abundance of native and exotic plants) in the grasslands and disturbed open space, because the plant species will compete with each other for resources (light, space, food.

    It is predicted that as the abundance of native plants increases, the fewer exotic plants you will see present in a habitat.

    B. It was hypothesized that there will be more woody plants in the grassland habitat than in the disturbed open space. In the disturbed area the soil is not favourable for the growth of the large woody plants and flowers, thus the ground coverage will be higher and abundance of woody plants will be close to zero. It was predicted that woody plants will be more abundant in grassland compare to the disturbed area.

    C. It was hypothesized that in the grassland there are more vertebrates and invertebrates than in the disturbed open space.

    It is predicted that more vertebrates will be observed in the grassland than in the disturbed open space after surveying a 50-meter radius for 15 minutes. It is also predicted that more invertebrates will be observed in the grassland than in the disturbed open space after surveying a 5-meter radius for 15 minutes.

    It is predicted that there will be a lot of invertebrates in the sweep nets in the grasslands and little in the sweep nets in the disturbed open space. There will be a lot of invertebrates in the pan traps in the grassland and little in the pan traps in the disturbed open space.

    Time Data Was Collected: Tuesday, October 4, 2016. 3:20-4:35 EST.

    Location of Data: Grassland and adjacent disturbed at York University, near York Boulevard. Latitude and longitude: 43.775, -79.505 (grassland) and 43.775 -79.5055 (disturbed grassland).

    Weather Conditions: 19 degrees Celsius, clear, Sunny and dry conditions.

    Survey Method:

    A. The field experiment was conducted using the quadrat sampling technique. A 50m transect was placed on the ground. An individual would walk along this transect and place a quadrat every 2 meters, alternating left and right along the transect. Each time the quadrats were placed, the total number of exotic and native plants, as well as the total number of flowers within the quadrats were counted and recorded. This sampling technique was repeated for a total of 25 times. Similarly, in the disturbed open space, this method was replicated. However, in order to get an estimation of the exotic plants, the quadrats were visually divided into sections of 16. The abundance of exotic plants was counted for 1 section, which was then used to estimate the abundance in the entire quadrat.

    B. This experiment was completed using transect. 25 replicates were conducted in the grassland and 25 replicates in the disturbed open area. Every two meters along a transect of 50 meters, abundance of woody plants was measured on either side of the transect within 0.5 meters. At these points canopy coverage was observed and recorded by making a square with fingers and holding up and estimating how much of sky you can see. Using the same method the ground coverage was estimated. To measure the ground coverage, a visual area was divided into quadrats, then sum the area covered. At end the total number of flowers was also recorded.

    C. A 50-meter transect was established perpendicular to the periphery of the grassland. Standing at the beginning of the transect, a 50-meter radius was surveyed. The number of vertebrates, the types of vertebrate species, and the number of people (who were not members of the BIOL 2050 Ecology Lab) observed in 15 minutes were recorded. Then, a 5-meter radius from the beginning of the transect was surveyed for 15 minutes. The number of individual invertebrates observed within this 5-meter radius in 15 minutes was recorded.

    The above procedure was repeated in the adjacent disturbed open space.

    D. 12 bowls with a 6cm diameter and 5cm depth were filled with soapy water and placed in 3m intervals, with 6 bowls in the grassland and 6 in the disturbed open space. The bowl colors were alternated between yellow, blue, and white. The bowls were left for 30 minutes and then the number of invertebrates in the bowl was counted. While waiting the 30 minutes for the pan trap bowls, 50 meters were walked while swinging a sweep net with a 32 cm and a depth of 73 cm from side to side. At the end of the 50 meters, the number of invertebrates captured inside was counted and then the invertebrates released. This method was repeated 10 times in the grassland and 10 times in the disturbed open space.

    Equipment Used:

    • transects

    • 12 plastic bowls with a 6cm diameter and 5cm depth. 4 bowls were blue, 4 bowls were white, and 4 bowls were yellow.

    • 1 sweep net with a diameter of 32 cm and a depth of 73 cm was used to conduct all the sweep net trials.

    • quadrats measuring 1 meter by 1 meter

    Additional Information:

    Hypothesis and Predictions:

    A. It was hypothesized that fewer invertebrates and vertebrates will be found in the forest as temperature decreases.

    It is predicted that fewer vertebrates will be observed in the forest on October 25th, 2016 than were observed on September 27th, 2016 after surveying a 50-meter radius for 15 minutes. It is also predicted that fewer invertebrates will be observed in the forest on October 25th, 2016 than were observed on September 27th, 2016 after surveying a 50-meter radius for 15 minutes

    It is predicted that there will be less invertebrates in the pan traps on October 25th, 2016 than there were on September 27th, 2016. It was also predicted that there will be fewer invertebrates in the sweep nets on October 25th, 2016 than there were on September 27th, 2016.

    B. It is hypothesized that there will be a negative relationship between the 2 variables, (abundance of native and exotic plants) in the forest, because the plant species will compete with each other for resources (light, space, food).

    It is predicted that as the abundance of native plants increases, the fewer exotic plants you will see present the forest.

    C. It was hypothesized that there is a negative correlation between number of the woody plants and total number of the flowers in the forest. It was predicted that number woody plants will be higher than number of the flowers. The reason is that the percentage of the canopy coverage is higher near the woody plants, therefore blocking the sunlight for the growth of the vegetation and flowers below the trees. Sunlight is an essential source for the growth and photosynthesis of the flowers, less exposure will result in less growth of the small plants.

    Time Data Was Collected: Tuesday, October 25, 2016. 2:45-3:15 EST.

    Location of Data: Forest at York University. Latitude and longitude: 43.768756, -79.5079 and 126.30201.

    Weather Conditions: 9 degrees Celsius, sunny, clear conditions.

    Survey Method:

    A. The field experiment was conducted using the quadrat sampling technique. A 50m transect was placed on the ground in the forest. An individual would walk along this transect and place a quadrat every 2 meters, alternating left and right along the transect. Each time the quadrats were placed, the total number of exotic and native plants, as well as the total number of flowers within the quadrats were counted and recorded. This sampling technique was repeated for a total of 25 times.

    B. This experiment was completed using transects. 25 replicates were conducted in the forest. Every two meters along a transect of 50 meters, abundance of woody plants was measured on either side of the transect within 0.5 meters. At these points canopy coverage was observed and recorded by making a square with fingers and holding up and estimating how much of sky you can see. Using the same method the ground coverage was estimated. To measure the ground coverage, a visual area was divided into quadrats, then sum the area covered. At end the total number of flowers was also recorded.

    C. A 50-meter transect was established perpendicular to the periphery of the forest. Standing at the beginning of the transect, a 50-meter radius was surveyed. The number of vertebrates, the types of vertebrate species, and the number of people (who were not members of the BIOL 2050 Ecology Lab) observed in 15 minutes were recorded. Then, a 5-meter radius from the beginning of the transect was surveyed for 15 minutes. The number of individual invertebrates observed within this 5-meter radius in 15 minutes was recorded.

    D. 12 bowls with a 6cm diameter and 5cm depth were filled with soapy water and placed in 3m intervals in the forest. The bowl colors were alternated between yellow, blue, and white. The bowls were left for 30 minutes and then the number of invertebrates in the bowl was counted. While waiting the 30 minutes for the pan trap bowls, 50 meters were walked while swinging a sweep net with a 32 cm and a depth of 73 cm from side to side. At the end of the 50 meters, the number of invertebrates captured inside was counted and then the invertebrates released back to the forest.

    Equipment Used:

    • transects

    • 12 plastic bowls with a 6cm diameter and 5cm depth. 4 bowls were blue, 4 bowls were white, and 4 bowls were yellow.

    • 1 sweep net with a diameter of 32 cm and a depth of 73 cm was used to conduct all the sweep net trials.

    • quadrats measuring 1 meter by 1 meter

Description

This data package contains identifiers, metadata, and a map of the locations where field measurements have been conducted at the East River Community Observatory located in the Upper Colorado River Basin, United States. The East River is the primary field site of the Watershed Function Scientific Focus Area (WFSFA) and the Rocky Mountain Biological Laboratory. Researchers from over 30 institutions generate highly diverse hydrological, biogeochemical, climate, vegetation, geological, remote sensing, and model data at the East River in collaboration with the WFSFA. Thus, the purpose of this data package is to maintain an inventory of the field locations and instrumentation to provide information on the field activities in the East River and coordinate data collected across different locations, researchers, and institutions. The data package contains (1) a README file with information on the various files, (2) three csv files describing the metadata collected for each surface point location, plot and region registered with the WF SFA, (3) csv files with metadata and contact information for each surface point location registered with the WF SFA, (4) a csv file with with metadata and contact information for plots, (5) a csv file with metadata for geographic regions and sub-regions within the watershed, (6) a compiled xlsx file with all the data and metadata which can be opened in Microsoft Excel, and (7) a kmz map of the locations plotted in the watershed which can be opened in Google Earth. Persistent location identifiers are determined by the WFSFA data management team and are used to track data and samples across locations. Researchers interested in having their East River measurement locations added in this list should reach out to the WFSFA data management team at wfsfa-data@googlegroups.com.
