gdal_warp produce wrong (unequal) cell size
|Reported by:||miro||Owned by:||warmerdam|
When I clip raster to polygon shapefile (both in GDA94 Z56 - EPSG:28356) the result has unequal cell size like:
Example for big raster about 10000x10000 cells and 5x5m cell size:
Pixel Size = (4.999893471194129,-5.000074452387987)
Example with 75x75m pixels and significantly smaller clip areas - rectangles:
Pixel Size = (75.156717048047454,-75.009639323886461) Pixel Size = (75.096859834735284,-75.241627899123372)
It might seem like nothing but some tools needs exact square dimensions which makes in these cases clipped grids useless...
