Bug report #9413
Misalignment after raster clipping
|Affected QGIS version:||2.0.1||Regression?:||No|
|Operating System:||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||worksforme|
|Crashes QGIS or corrupts data:||No||Copied to github as #:||18008|
After clipping of a raster with a vector mask layer using the "gdalwarp -q -cutline" function, the clipped raster shows a misalignment with regard to the original raster. Using the same coordinate systems for all involved datasets (EPSG 4326: WGS84), the observed misalignment is around a quarter of the raster cell size. The same procedure with the same datasets in ArcGIS does not result in such a misalignment. The bug has been observed on the current version of QGIS Desktop 2.0.1 with GDAL/OGR 1.10.0

Does it happens if you launch the command (that shows in the bottom of the clip tool dialog) from the command line?
If yes then it can be a gdal issue, not a qgis one, or maybe it is just matter of tuning/adding a parameter.
Please try and report back.

Probably needs an argument like -tap
interesting, what others tools (if any) would benefit from this parameter?
Anyway I just tested on qgis master with a raster and a mask both in WGS84 and the result has no shift.
So... can you teste qgis master and/or attach your data? Thanks.
