-Abstract MTK_SOMXY_TO_LATLON converts from Space Oblique Mercator (SOM) X and Y coordinates to decimal latitude and longitude or a given MISR path. -Copyright Copyright (2005), California Institute of Technology. U.S. Government sponsorship acknowledged. -I/O Given: path MISR path somx SOM X in meters somy SOM Y in meters the call: status = MTK_SOMXY_TO_LATLON( path, somx, somy, lat, lon ) returns: status 0 on success; otherwise failure lat decimal latitude lon decimal longitude -Examples ;; ;; Set up input parameters ;; path = 230 somx = 17145920.0 somy = 222090.0 status = MTK_SOMXY_TO_LATLON( path, somx, somy, lat, lon ) ;; ;; Output... ;; print, 'path : ', path print, 'SOM X : ', somx print, 'SOM Y : ', somy print, '=================================================' print, 'LATITUDE : ', lat print, 'LONGITUDE : ', lon IDL outputs: path : 230 SOM X : 1.71459e+07 SOM Y : 222090. ================================================= LATITUDE : 26.737612 LONGITUDE : -54.149627 -Particulars None. -Required Reading For important details concerning this module's function, please refer to the MTK routine MtkSomXYToLatLon.c. -Version -IDL-MTK Version 1.2.0
