Facing problemas with "Clip DEM with polygon layer" tool #264

Closed GeoPontes closed 2 years ago

GeoPontes commented 2 years ago

Hey guys!

First, thanks creating and maintaning this amazing tool. Secondly, I'd like to report an strange behaviour that I'm experiencing in QGIS 3.16. I have a raster layer obtained through processing of a considerable number of SRTM files (30m of spacial resolution). Also, I have a .shp which delimites the catchment area of a brazillian basin. Both files match in extent and coordinate system. (figure 1)

Whenever I try to utilize the "Clip DEM with polygon layer" tool, within "Layer Properties" Menu, the plugin screen frozes (figure 2). I also get an error on QGIS. Actually a yellow bar appears suggesting me to check for erros on the log file (figure 3). The errors, both from Python and Qgis2threejs are shown below. Other presentation set ups work fine.

Could anyone have a hint on what may be the cause of the problem I’m facing?

Thanks!

Hi! I keep getting the same error, did you find a solution to this?

Hi! I keep getting the same error, did you find a solution to this?

I managed to solve it by simplifying the vector layer that i was using to crop the raster layer in QGIS2ThreeJS.

QGIS can perform this vector layer simplification in: Vector -> Geometry -> Simplify (you should test configurations that are suited for your vector layer, but is easir to oversimplify and calibrate from it).

Best of luck!
