Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.
I am attempting to use the mcidas meteosat navigation module The documentation is obscure. 1. Sometimes Mcidas lists longitude positive to the west. 2. line and elemement numbers are interchangable in some sence since the Meteosat 7 satellite is at 0 longitude. 3. Line numbers could count from south to north or north to south. Similarly element numbers could count either increasing to the west (as the satellite scans) or increasing to the east (as a picture would show). Has anyone used edu.wisc.ssec.mcidas.MSATnav? What convention do you use for latitude and longitude/ line and element in the routines calls to toLatLon and toLinEle. G. Garrett Campbell Ph. D.
