## DESCRIPTION

This program outputs, in ASCII, the values in a raster map which lie along one or more user-defined transect lines. The transects are described by their starting coordinates, azimuth, and distance.

The line parameter is a definition of (each) transect line, specified by the geographic coordinates of its starting point (easting, northing), the angle and direction of its travel (azimuth), and its distance (distance).

The azimuth is an angle, in degrees, measured to the east of north. The distance is in map units (meters for a metered database, like UTM).

The null parameter can optionally be set to change the character string representing null values.

## NOTES

This program is a front-end to the r.profile program. It simply converts the azimuth and distance to an ending coordinate and then runs r.profile. There once were width= and result=raw|median|average options which are not currently implemented.
