I'm attempting to crop a raster with gdal warp using python bindings, the code works fine as I use it to crop a raster approximately 3k times, of which a couple fail with the following error and produce no outputs:

gdal warp cutline invalid

So following some online suggestions I added the following line of code:

gdal.SetConfigOption("GDALWARP_IGNORE_BAD_CUTLINE", "YES")

which then changes the error I get to the following: 

gdal Points of LinearRing do not form a closed linestring

So from this I can see that the polygons that I generated from a linestring then buffered using ogr aren't correct. I've then gone and extracted the geometry as a WkT so I can check them, I've included the full list at this URL: https://pastebin.com/d60L3nni .

Now I'm still stuck because the first and last point are at exactly the same coordinates: 

-1406502.73228006 6411785.18363632

and 

-1406502.73228006 6411785.18363632

Sure because the first and last points are on the same coordinates then it should be a valid polygon? I've tried passing this throught ArcMap Repair Geometry and it also passes the geometry.IsValid() check in ogr.

  • The geometry is valid but it is quite large. How do you pass it to GDAL? Could it be possible that the input gets truncated because of too long string?

  • It's a two step process, first the linestring is buffered into a polygon and saved to a shapefile, this shapefile is then passed directly to gdal warp.

  • I put your coordinates into WKT POLYGON, converted it into shapefile and used it as cutline for gdalwarp. gdalwarp test.tif out.tif -cutline cutline.shp. I did not get any errors. GDAL version is 3.0.2.

  • I've upgraded to 3.0.2 as well and I can confirm that has fixed it for me! If you want to add that as an answer I'd be happy to accept it. Unfortunately I have other issues with 3.0.2 and pyinstaller at the moment so I'll have to ask another question as well.

With GDAL 3.0.2 gdalwarp works for me with command

gdalwarp test.tif out.tif -cutline cutline.shp

where cutline.shp contains your polygon
