This project was a cooperative effort between the National Ocean Service and the Florida Department of Environmental Protection's Florida Marine Research Institute (now called the Fish and Wildlife Research Institute). The goal of the effort was to produce shallow-water (from 0 to approximately 30 m water depth) benthic habitat maps of the Florida Keys and adjacent waters. The maps were generated by expert visual interpretation of 1:48,000 scale color aerial photography and subsequent photogrammetric, stereo, digital compilation of interpreted habitat polygon boundaries from aerial photography. The Minimum mapping unit = 0.4 hectare (4,047 sq m; 1 acre) for all habitat. Patch reefs may be <0.5 ha. The aerial photography was acquired using a NOAA jet from December 1991 through March 1992. The photography was acquired with 60% side and 80% forward overlap to facilitate stereo compilation. Approximately 450 aerial photographs were acquired and used for the mapping project. Ground validation of interpreted habitat polygons was performed by visual verification at actual field sites prior to compilation. Aircraft Inertial Measurement Unit data were used to correct photography positioning in photogrammetric analytical plotters. The analytical solution used in the photogrammetric plotter for positioning was applied to bundles of 30-40 adjacent, overlapping aerial photographs. The stereo positioning of the photography was < 1 m. Digital data for bundles of compiled aerial photographs from the photogrammetric stereo plotter was imported into the ESRI ArcInfo GIS. The GIS was used to merge and edit the vector and attribute features of the 15 bundles to generate a mosaic benthic habitat map of the Florida Keys and adjacent areas covered by the aerial photography. Field validation of digitized habitat features visible in the aerial photography mosaics was performed to ensure correct interpretation. An assessment of the correctness of the interpreted digital map was performed by experts familiar with the the seafloor habitat found in the Florida Keys.

These data serve as documentation for seagrass coverage in the Indian River Lagoon in 1974. Seagrass coverage was photointerpreted from 1974 aerials at 1:23,000 scale black and white transparencies. Features were classified according to SFWMD/SJRWMD modified FLUCCS using photogrammetric techniques; ground control obtained from GPS survey and USGS DOQQs, aerotriangulation of aerial photography, and stereo compilation using analytical stereoplotters using a minimum mapping unit of 0.25 acres (=0.1 hectares).These data document and inventory seagrasses for the management of the resource, identify "healthy" areas that may deserve special protection efforts, and identify potential "problem" areas that require further investigation. These data are intended for use in documenting large-scale trends in the status of this resource.

Produced by Teagasc (Kinsealy), EPA and GSI.The dataset was created using a compilation of existing data, photogrammetric mapping, field studies. Soil survey maps, Quaternary maps and published and unpublished reports were complied and boundaries between sediment types are interpreted and mapped using photo-interpretation in a soft copy photogrammetric workstation with digital stereo-pairs of black and white photography acquired at a scale of 1:40,000. Fieldwork was carried out, around the flanks of large bogs delineate the exact boundary between peat and mineral soils but predominantly within the boundary zones of differencing subsoils. Areas mapped during the photogrammetric analysis were also checked during the fieldwork. Methods adopted during field mapping include reconnaissance mapping, auger sampling, trenching, digital photography and GPS data recording. Aerial photography datasets involved in mapping were acquired in 1995 while field data collected was collected during 1998-2005.The classification of subsoils is based on the classification used by the Geological Survey of Ireland Quaternary Section in mapping Quaternary sediment types.This classification has been altered only to ensure utility specific to the requirements of the EPA Soil and Subsoil Mapping Project.

The U.S. Geological Survey (USGS) Aerial Photography data set includes over 2.5 million film transparencies. Beginning in 1937, photographs were acquired for mapping purposes at different altitudes using various focal lengths and film types. The resultant black-and-white photographs contain less than 5 percent cloud cover and were acquired under rigid quality control and project specifications (e.g., stereo coverage, continuous area coverage of map or administrative units). Prior to the initiation of the National High Altitude Photography (NHAP) program in 1980, the USGS photography collection was one of the major sources of aerial photographs used for mapping the United States. Since 1980, the USGS has acquired photographs over project areas that require photographs at a larger scale than the photographs in the NHAP and National Aerial Photography Program collections.

Description

Urbansas is a dataset for the development and evaluation of machine listening systems for audiovisual spatial urban understanding. One of the main challenges to this field of study is a lack of realistic, labeled data to train and evaluate models on their ability to localize using a combination of audio and video.
We set four main goals for creating this dataset:
1. To compile a set of real-field audio-visual recordings;
2. The recordings should be stereo to allow exploring sound localization in the wild;
3. The compilation should be varied in terms of scenes and recording conditions to be meaningful for training and evaluation of machine learning models;
4. The labeled collection should be accompanied by a bigger unlabeled collection with similar characteristics to allow exploring self-supervised learning in urban contexts.
Audiovisual data
We have compiled and manually annotated Urbansas from two publicly available datasets, plus the addition of unreleased material. The public datasets are the TAU Urban Audio-Visual Scenes 2021 Development dataset (street-traffic subset) and the Montevideo Audio-Visual Dataset (MAVD):

Wang, Shanshan, et al. "A curated dataset of urban scenes for audio-visual scene analysis." ICASSP 2021-2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP). IEEE, 2021.

Zinemanas, Pablo, Pablo Cancela, and Martín Rocamora. "MAVD: A dataset for sound event detection in urban environments." Detection and Classification of Acoustic Scenes and Events, DCASE 2019, New York, NY, USA, 25–26 oct, page 263--267 (2019).

The TAU dataset consists of 10-second segments of audio and video from different scenes across European cities, traffic being one of the scenes. Only the scenes labeled as traffic were included in Urbansas. MAVD is an audio-visual traffic dataset curated in different locations of Montevideo, Uruguay, with annotations of vehicles and vehicle components sounds (e.g. engine, brakes) for sound event detection. Besides the published datasets, we include a total of 9.5 hours of unpublished material recorded in Montevideo, with the same recording devices of MAVD but including new locations and scenes.

Recordings for TAU were acquired using a GoPro Hero 5 (30fps, 1280x720) and a Soundman OKM II Klassik/studio A3 electret binaural in-ear microphone with a Zoom F8 audio recorder (48kHz, 24 bits, stereo). Recordings for MAVD were collected using a GoPro Hero 3 (24fps, 1920x1080) and a SONY PCM-D50 recorder (48kHz, 24 bits, stereo).

When compiled in Urbansas, it includes 15 hours of stereo audio and video, stored in separate 10 second MPEG4 (1280x720, 24fps) and WAV (48kHz, 24 bit, 2 channel) files. Both released video datasets are already anonymized to obscure people and license plates, the unpublished MAVD data was anonymized similarly using this anonymizer. We also distribute the 2fps video used for producing the annotations.

The audio and video files both share the same filename stem, meaning that they can be associated after removing the parent directory and extension.

Annotations

Of the 15 hours of audio and video, 3 hours of data (1.5 hours TAU, 1.5 hours MAVD) are manually annotated by our team both in audio and image, along with 12 hours of unlabeled data (2.5 hours TAU, 9.5 hours of unpublished material) for the benefit of unsupervised models. The distribution of clips across locations was selected to maximize variance across different scenes. The annotations were collected at 2 frames per second (FPS) as it provided a balance between temporal granularity and clip coverage.

The annotation data is contained in video_annotations.csv and audio_annotations.csv.

Video Annotations

Each row in the video annotations represents a single object in a single frame of the video. The annotation schema is as follows:

• frame_id: The index of the frame within the clip the annotation is associated with. This index is 0-based and goes up to 19 (assuming 10-second clips with annotations at 2 FPS)
• track_id: The ID of the detected instance that identifies the same object across different frames. These IDs are guaranteed to be unique within a clip.
• x, y, w, h: The top-left corner and width and height of the object’s bounding box in the video. The values are given in absolute coordinates with respect to the image size (1280x720).
• class_id: The index of the class corresponding to: [0, 1, 2, 3, -1] — see label for the index mapping. The -1 value corresponds to the case where there are no events, but still clip-level annotations, like night and city. When operating on bounding boxes, class_id of -1 should be filtered.
• label: The label text. This is equivalent to LABELS[class_id], where LABELS=[car, bus, motorbike, truck, -1]. The label -1 has the same role as above.
• visibility: The visibility of the object. This is 1 unless the object becomes obstructed, where it changes to 0.
• filename: The file ID of the associated file. This is the file’s path minus the parent directory and extension.
• city: The city where the clip was collected in.
• location_id: The specific name of the location. This may include an integer ID following the city name for cases where there are multiple collection points.
• time: The time (in seconds) of the annotation, relative to the start of the file. Equivalent to frame_id / fps .
• night: Whether the clip takes place during the day or at night. This value is singular per clip.
• subset: Which data source the data originally belongs to (TAU or MAVD).

Audio Annotations

Each row represents a single object instance, along with the time range that it exists within the clip. The annotation schema is as follows:

• filename: The file ID odd the associated audio file. See filename above.
• class_id, label: See above. Audio has an additional class_id of 4 (label=offscreen) which indicates an off-screen vehicle - meaning a vehicle that is heard but not seen. A class_id of -1 indicates a clip-level annotation for a clip that has no object annotations (an empty scene).
• non_identifiable_vehicle_sound: True if the region contains the sound of vehicles where individual instances cannot be uniquely identified.
• start, end: The start and end times (in seconds) of the annotation relative to the file.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The vegetation classification and mapping processes were conducted essentially in tandem. Mappers and ecologists conferred to review the list of potential associations, as well as the appropriate scale for mapping. Photos were viewed in stereo and preliminary polygon boundaries were delineated with a .30-mm rapidograph pen on polypropylene sleeves placed over the aerial photos. Preliminary polygons were classified and labeled with their appropriate USNVC association using the aerial photograph interpretation key and USNVC descriptions, and by conferring with NatureServe ecologists. The initial line work was also used to determine a sampling scheme for plot and observation data collection, and the USNVC association list resulting from the field work was used to aid polygon classification. Once delineations were groundtruthed and rectified, USNVC association-level polygon line work was transferred to GIS shapefiles via onscreen digitizing in ArcView v.3.2a (ESRI 1992–2000). USNVC association and Anderson Level II (modified) land use names and codes were added to the attribute table of the vegetation shapefile. A separate wetland map for the park was created from the vegetation map polygons belonging to the Saturated Cold-deciduous Forest and Saturated Temperate Perennial Forb Vegetation formations.

These data serve as documentation for seagrass coverage in the Indian River Lagoon in 2005. Seagrass coverage was photointerpreted from 2005 1:24,000 scale natural color aerial photography. Features were classified according to SFWMD/SJRWMD modified FLUCCS using photogrammetric techniques; ground control obtained from GPS survey and USGS DOQQs, aerotriangulation of aerial photography, and stereo compilation using analytical stereoplotters using a minimum mapping unit of 0.25 acres (=0.1 hectares). The horizontal accuracy of the data meets national map accuracy standards (NMAS) for 1:24,000 scale maps (+/- 40 feet). A thematic accuracy assessment was performed on the data.These data document and inventory seagrasses for the management of the resource, identify "healthy" areas that may deserve special protection efforts, and identify potential "problem" areas that require further investigation. These data are intended for use in documenting large-scale trends in the status of this resource. The Indian River Lagoon (IRL) Surface Water Improvement and Management (SWIM) Plan directs the South Florida and St. Johns River Water Management Districts to map seagrasses in the Indian River Lagoon at two to three-year intervals.For reference access the following documents:Aerial Triangulation ReportFinal ReportPIKeyMapping MethodsSegments Map LocationSWIM Plan Update
