RSL_get_linear_value
Synopsis
#include "rsl.h"
float RSL_get_linear_value(Volume *v, float srange, float azimuth, float elev, float limit);
Description
Find a linearly interpolated value in the Volume, v, at the polar coordinate specification (srange, azimuth, elev). The four surrounding data values that are azimuthally within +/- limit degrees are used for the interpolation. Limit is measured in degrees. Srange is the slant range in KM. Azimuth and elev are measured in degrees.
Return value
Upon successful completion, a valid floating point number is returned. Note, the value could be BADVAL.
