This gzipped tar achive contains Matlab utilies for manipulaing SIR file format image files. The SIR file format is used by the NASA Scatterometer Climate Record Pathfinder (SCP) project to distribute scientific data.
The BYU-MERS "sir" image format was developed by the Brigham Young University (BYU) Microwave Earth Remote Sensing (MERS)research group as part of the NASA Scatterometer Climate Record Pathfinder (SCP) project to store remotely sensed images of the earth used for climate studies, among other purposes. The file format stores an image array of floating point values along with the information required to earth-locate the image pixels. The SIR file header contains the transformation information to convert from pixel location to lat/lon and visa versa. Additional information on the applications, file format,and available data can be obtained from the NASA-sponsored Scatterometer Climate Record Pathfinder web site http://www.scp.byu.edu/ and/or the NASA/JPL PO.DAAC http://podaac.jpl.nasa.gov/
Files in this tar arhive are useful for reading SIR files into MATLAB and locating pixels. Use loadsir.m to load the file into memory. The routine pix2latlon.m computes the lat/lon position given a list of x,y pixel locations. latlong2pix does the reverse. showsir and viewsir are utilities to display SIR images.
