Description

In the gdal-16 version of OSGeo4W, multi-part polygons are not supported in gdalwarp for use as cutlines. When this is attempted, the message "ERROR: Did not get any cutline features" is displayed.

As an example, the following command was used with the attached files: 

  
C:\apps\OSGEO4W\apps\gdal-16\bin\gdalwarp -order 1 -r near -cutline E:/POPS/temp/req29244_aoi.shp -cblend 0 E:\POPS\temp\piece1411016_temp0.tif E:\POPS\temp\piece1411016_temp1.tif

Actually, the attachment was too large. It can be found here:

  • status changed from new to closed
  • component changed from default to Utilities
  • version changed from unspecified to 1.6.0
  • milestone set to 1.6.1
  • keywords gdalwarp cutline added
  • resolution set to fixed

It turns out that the underlying mechanisms supported multipolygons, but that gdalwarp's logic for accumulating polygons and multipolygons into one big multipolygon was not correct and was discarding the multipolygons.

Corrected in trunk (r16939) and 1.6 branch (r16940).

I have uploaded a new OSGeo4W gdal16 package (gdal-1.6.0-9).
