GDAL 2.1.1: gdalwarp to VRT produces large output file if cropping to cutline
|Reported by:||cxcandid||Owned by:||warmerdam|
During some tests with gdalwarp, i recognized a change between GDAL 1.11.4 and GDAL 2.1.1 regarding the creation of VRT files.
When cropping to a rectangular cutline, the output VRT file is much larger in GDAL 2.1.1 than in GDAL 1.11.4. The larger size results from an automatic segmentation of the cutline, which produces a lot of additional vertex points. Using GDAL 1.11.4 the resulting VRT files are much smaller, because there is no cutline segmentation.
Is this behavior intended?
Are there any settings or flags to disable the automatic segmentation?
Best regards and my thanks for your efforts!
