Advances in technology enable CSA’s analysts to integrate digital video with geospatial information (latitude, longitude, and metadata), resulting in videospatial data that enables more powerful analysis of digital imagery.
CSA specializes in the collection, processing, and analysis of videospatial data, integrating video with spatial attributes such as bathymetry, elevation, environmental data, habitat maps, and infrastructure locations.
The result is a powerful tool for capturing geospatially articulated information from within the video image and rendering that information into a GIS for further analysis.
CSA’s Videospatial Services include:
- Designing videospatial imaging surveys with an understanding of Motion Industry Standards Board (MISB) metadata requirements
- Collecting imagery using any platform (underwater ROVs, UAVs/drones, diver-held video, helicopter, fixed-wing aircraft, and others)
- Integrating video imagery, navigational data, and metadata
- Conducting desktop analysis to extract points, lines, and polygons directly from video using Esri’s Full Motion Video (FMV) add-in
- Providing a web-based platform customized for managing, viewing, and delivering video in a geospatial context
Watch the movie below to see an example of how videospatial data are analyzed on the desktop, to extract points, lines and polygons directly from the video frame.
The video to the above shows an example of FMV-compliant imagery collected from an aerial platform and analyzed using ESRI’s ArcMap software and Full Motion Video add-in. It illustrates how the user can extract geospatial information from the video by digitizing points, lines, or polygons directly on the imagery. In this example, beachgoers on Jupiter Island, Florida, are digitized as points, which are then saved as a shapefile.
Applications of videospatial data analysis include:
- Nearshore hardbottom mapping
- Protected species observation
- Fish counts
- Seafloor surveys
- Oil spill and disaster response
- Coral and seagrass habitat mapping
- Coastal feature mapping
- Archaeological surveys
- Debris surveys
- Pipeline inspection
- Search and rescue
- Human and wildlife use activities
CSA’s web-based EDGSonline application virtually centralizes data, documents, and video in a secure geospatial map interface. Cloud-based hosting in EDGSonline allows users to view, manage, and download a library of video files, extract the latitude and longitude position of observations in video, and create annotations.
In the example below, a screen capture from EDGSonline shows video imagery of grazing manatees (left panel), the spatial location of the image collection platform (helicopter icon, right panel), and the spatial extent of camera’s field of view (rectangle, right panel).
