pixel block from IPixelFilter

Discussion created by yacc on Jan 28, 2011
Hi All,

I have a shapefile with various polygons and need to query several temporal rasters (eg. Maximum temperature) for a selected shape and extract pixel values for the extent of the polygon.

I used the clipfilter method (after clipping and resampling) as described in


However, the method creates a raster with values in the extent of polygon shape and nodata values in all other places.

Is there any method to access the pixel blocks using the filter and get the pixel values? I tried looking for it and haven't found any info.
