GIS background maps:
AirWare uses minimally two basic background maps:
- Satellite background map, derived from LANDSAT 7 panchromatic
band at 15 m resolution.
- DEM at 1 km resolution, derived from the USGS
global 30 arc second
GTOPO30 data set;
While the satellite image is primarily used as a geographical background
and reference for all georeferenced data and model results,
the DEM is used in the calculations (both meteorology and air quality)
as input data set.
