Software readers and utilities for the BYU-MERS "SIR" image format in various languages. The BYU-MERS "sir" image file format was developed by the Brigham Young University (BYU) Microwave Earth Remote Sensing (MERS) research group in the 1990's to store scatterometer images of the earth along with the information required to earth-locate the image pixels. Note that in standard BYU sir files the pixel addresses run from 1 to N rather than than from 0 to N-1. Pixel (1,1) is in the lower left of the image. For an input (1,1) the Lat,Lon values for correspond to the lower-left corner of the (1,1) pixel. In a standard BYU sir file, the file header (first 512 bytes) store meta information about the file, including the projection and transformation information. The readers in the subdirectories are designed to implement pixel to lat/lon and the reverse as well as read and write sir files. Source code for read/writing and analyzing sir files is available in c, fortran (several flavors), c++, matlab, idl, and python. On standard linux machines, use "make" to create library and compile test programs. =========================================================================== Dr. David G.
