I have a series of raster files of infrared aerial imagery. I would like to intersect them with a set of polygons in a shapefile and return the average (or frequency) of the RGB channels in the rasters. Could anyone advise if this is possible please?

 

Thanks

Rob

If I understand what you need, yes this is possible.

  • Readers for the raster and the shape.
  • Clipper to clip the raster.
  • RasterStatisticsCalculator to return the values you need.
  • Writer to output your result.
