◆ rt_raster_overlaps()

rt_errorstate rt_raster_overlaps ( rt_raster  rast1,
int  nband1,
rt_raster  rast2,
int  nband2,
int *  overlaps 
)

Return ES_ERROR if error occurred in function.

Parameter overlaps returns non-zero if two rasters overlap

Parameters
rast1: the first raster whose band will be tested
nband1: the 0-based band of raster rast1 to use if value is less than zero, bands are ignored. if nband1 gte zero, nband2 must be gte zero
rast2: the second raster whose band will be tested
nband2: the 0-based band of raster rast2 to use if value is less than zero, bands are ignored if nband2 gte zero, nband1 must be gte zero
overlaps: non-zero value if the two rasters' bands overlaps
Returns
ES_NONE if success, ES_ERROR if error
