EPSG projection can't be recognized by SNAP?

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!


it is true. The data is not correctly read. I’ve created an issue for this and we will take for this in the future. But I can’t promise that it will be solved any time soon.

Maybe it is possible to convert the data somehow with, maybe GDAL or similar software.
