Extract by mask issue

catcrawo — Wed, 18 Oct 2023 08:05:11 GMT

I want to cut .tiff by .shp and chose to use extract by mask. However, the result contains several white stripes as shown in picture. The value in these area are "Nodata", but the original .tiff does have values in these area. I would like to ask how could I solve this problem. Thanks in advance.

Try converting the shapefile to a local file geodatabase featureclass. Ensure that the coordinate system of the featureclass matches that of the raster.

Any difference when this is followed?

Alternately, convert the shapefile to a raster mask using the procedure outlined here

Thank you for your replay, but

When I converted .shp into .gdb and used Extract by Mask, the white stripes become even more.

When I only converted .shp into .tif without Extract by Mask, as shown in the picture, the .tif itself has included white stripes.

the shape file has issues then if it has those stripes, get the shapefile into edit mode and remove any spurious vertices that are in the interior

The shapefile does have issues. Thank you very much!

Excuse me, there is another question.

How could I remove those vertices after getting into the edit mode? I can't find the right tool.
