Equal Arc-Second Raster Chart/Map: The ARC system divides the surface of the earth ellipsoid into 9 latitudinal bands per hemisphere called zones. The (2) polar zones use the Azimuthal Equidistant projection. Each of the (16) non-polar zones use an Equirectangular projection with the standard parallel being the midpoint latitude for the zone. The ARC system is described in MIL-A-89007 (the ADRG specification) and is used by CADRG, ECRG, CIB and ECIB.
In the Polar Azimuthal Equidistant projections used in the ARC system, all points on the map are at the correct azimuth (direction) and proportionally correct distance from the respective pole. Meridians (lines of longitude) are straight. Parallels (lines of latitude) are circles centered at the respective pole.
In the Equirectangular projections used in the ARC system, meridians and parallels are straight lines of constant spacing, and meridians and parallels intersect at right angles. The projection distorts both area and angles, that is, it is neither equal area nor conformal. In each zone the image is stretched (on the poleward side of the midpoint latitude) and squashed (on the equatorward side of the midpoint latitude) in the East-West direction.
When FalconView displays an Equal Arc map it uses the latitude at the center of the map as the standard parallel, rather than using ARC zone midpoint latitudes, so the line of least distortion is always in view.

|Digital Terrain Elevation Data: a sampling of earth surface elevation values with respect to Mean Sea Level. The nominal sampling density for NGA Level 1 DTED is one sample every 3-arc-seconds in each direction (1 arc second is approximately 31 meters at the equator). The nominal sampling density for NGA Level 2 DTED is one sample every arc second in each direction. DTED has a nominal scale of 1:250 K. The DTED map category of FalconView consists of a rendered image based on elevation data.

|Enhanced Controlled Image Base: digital imagery that has been orthorectified and projected into the ARC system. ECIB imagery can be color (RGB) or panchromatic and is commonly available at 5, 1 and 0.5 meter resolutions. ECIB is compressed using JPEG 2000.
|Enhanced Compressed Raster Graphics: a set of digitized maps and chart images derived from ADRG or other sources though filtering, compression and reformatting. ECRG uses the ARC system like ADRG. ECRG has a minimum resolution of 254 DPI, the resolution used by ADRG; however, ECRG is compressed using JPEG 2000.
