-I/O
Given:
path MISR path
res resolution in meters
block block number (1-based)
line block fractional line (x.0 represents pixel center)
sample block fractional sample (x.0 represents pixel center)
the call:
status = MTK_BLS_TO_LATLON( path, res, block, line, sample, lat, lon )
returns:
status 0 on success; otherwise failure
lat latitude in decimal degrees
lon longitude in decimal degrees
