Screenshot of NLCD in use on radio frequency signal software

The map portion of this Softwright TAP Analysis screenshot indicates the National Land Cover Database land cover classifications along a radio frequency signal path along and north of Colorado Springs, Colorado, with the various colors representing land cover types (legend on the left). On the graphic below the map, the Y-axis (on the left) is showing the elevation of the signal path in meters.  The X-axis (along the bottom) is showing distance in kilometers.  The red line slanting across the top is the line of sight. The slanted blue line is the Fresnel Zone, which is a 3-dimensional elliptical area between a wireless transmitter and receiver. Obstructions within the Fresnel Zone would typically cause signal loss. Image courtesy of Softwright LLC
