This makes sense and have confirmed in testing that adding vertices along the contour prior to reprojection lead to a relatively significant 0.6 meter offset in my case than not having done so. On that note, when using a polygon as a cutline, the determination of the cut is done according to which side the center of the pixel is on? -- Sent from: http://osgeo-org.1560.x6.nabble.com/GDAL-Dev-f3742093.html _______________________________________________ gdal-dev mailing list [email protected] https://lists.osgeo.org/mailman/listinfo/gdal-dev
