Metashape EPSG:3857 not recognized by gdal2tiles
« on: February 17, 2022, 04:01:19 PM »
Dear,

When trying to tile a raster exported by Metashape in EPSG::3857 (WGS 84 / Pseudo-Mercator), gdal2tiles (https://gdal.org/programs/gdal2tiles.html) errors because of the included CRS information is unexpected.

ERROR 6: Cannot find coordinate operations from `ENGCRS["WGS 84 / Pseudo-Mercator",EDATUM[""],CS[Cartesian,2],AXIS["easting",east,ORDER[1],LENGTHUNIT["metre",1]],AXIS["northing",north,ORDER[2],LENGTHUNIT["metre",1]],ID["EPSG",3857]]' to `EPSG:3857'

Do you have any idea why the CRS info in the metashape tif is not read as EPSG:3857 (https://epsg.io/3857) but as a ENGCRS which seems weird?

Thank you in advance
Feel free to let me know if this is a gdal issue

Hello EE,

Do you perform the export via Metashape GUI or using the script? Or any of these approaches rises the similar problem with gdal?

Dear Alexey,

I noticed the issue when exporting from a script, but I also tried it through the GUI and it gives the same problem.
I also tried adding the EPSG:3857 WKT as prj file and adding it to Metashape, same result.

Thank you for your answer
