Dear all:
I am using the L3 soil moisture products (CATDS) in .nc format, and I opened one file in SNAP.
The projection of the file is EPSG:6933.
The “proj4text” of the file is “+proj=cea +lon_0=0 +lat_ts=30 +x_0=0 +y_0=0 +ellps=WGS84 +units=m +no_defs”
It displayed well in SNAP, but after exported the file to BEAM-DIMAP format, the projection in the head file of the image changed to “WGS84(DD)”, which was as follows.
map info = {Geographic Lat/Lon,15.5,18.0,116.02222736244616,27.335476458072662,0.22055327892303467,0.22055327892303467,WGS84,units=Degrees}
coordinate system string = {GEOGCS[“WGS84(DD)”, DATUM[“WGS84”, SPHEROID[“WGS84”, 6378137.0, 298.257223563]], PRIMEM[“Greenwich”, 0.0], UNIT[“degree”, 0.017453292519943295], AXIS[“Geodetic longitude”, EAST], AXIS[“Geodetic latitude”, NORTH]]}
I opened the exported file in Arcgis, the longitude and latitude of the image is wrong.
can anyone help me?
Thanks in advance!
