WebApr 14, 2024 · GRS80 is an ellipsoid/spheroid, not a true geodetic datum / geographic coordinate system. If that's all that is listed (particularly for GRIDs or coverages), the software will create a "GRS80-based" geographic coordinate system. Because it's not a true GCS, we have no transformations to or from GRS80.

WebUTM (Universal Transverse Mercator) is a coordinate system that is based on the WGS84 ellipsoid. The UTM system divides the Earth into 60 zones, each 6° of longitude in width. The grid zones UTM 31N to 37N differ from the standard zone for the Northern Hemisphere, in part to accommodate the southern half of the Kingdom of Norway. WebWhat you said is usage for QGIS Desktop software. however I'm using QGIS API, and the CRS is WGS84, but there are some points that came from CGCS2000, how could I … WebOne simpler way would be to use the GDAL command line tools: gdalwarp infile.tif outfile.tif -t_srs "+proj=longlat +ellps=WGS84" That can be invoked easily enough via scripting for batch jobs. fisyuo
