Open Source Heads Up Pilots Display for Oblique Image Acquisition
To support our oblique imagery acquisition, we have developed an open-source heads up display for our pilots. The system utilizes a number of open tools and data such as: GPSD, PHP, OSSIM, MapBox GL JS API, TileServer, USGS National Map and Open Street Map. The system takes a realtime GPS stream and image collection information from the cameras to generate vector overlays the pilots can use to navigate and tracks progress to ensure full coverage of the survey area. This strategy has vastly improved the the efficiency with which we can collect imagery.
NOAA’s National Geodetic Survey supports homeland security and emergency response geospatial requirements by acquiring and rapidly disseminating spatially-referenced remote sensing datasets. Recently we have begun collecting oblique imagery immediately following an event to quickly provide situational awareness to emergency managers to assist in developing recovery strategies, to assess damage by comparing pre and post event imagery and to allow displaced residents to see images of their neighborhoods and homes.
