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.
