How To Read Binary YINSAR Backscatter Data and MAP Files
The YINSAR data (image) files are saved in raw binary format, using single precision
floating point decimal (i.e. 4 bytes per float), row ordered. The image sets are size x (row) by
y (col), as specified, with one float per pixel. The map sets are of size x by y,
as specified, with three floats per location: UTM Easting, Northing, and
Altitude using UTM Zone 13 S. The map files are in general a few lines longer
than the images because the GPS units collect data for a few moments longer
than the radar. This can be resolved, however, by simple trunction of the extra
lines, if desired. Images are scaled backscatter (arbitrary units) while maps are height in meters UTM. Note: Image backscatter has not been corrected for aircraft roll.
