7.5.3 Elevation Data
The elevation maps used in this app are from the Shuttle Radar Topography Mission
(SRTM), which collected elevation data of the Earth’s surface between 60 degrees north and
56 degrees south latitudes in February of 2000. The data points are posted every 1
arc-second (approximately 30 meters), with 1 meter of height resolution. Areas above 50
degrees north and below 50 degrees south are sampled at a resolution of 2 arc-second by 1
arc-second. Some map tiles may contain voids. For more information, see
Additional data sets may be incorporated in the future.
7.6 Map Overlays
PDF files with georeferenced maps (such as those created by Esri ArcMap), KMZ files,
KML files, and CSV files with latitude and longitude columns can be displayed as an overlay
on the map while flying.
