Good day FME'ers
I am trying to calculate the percentage green/grey from an single band NDVI raster image, i.e. the percentage of the raster that have cell values >= and < -0.1.
Can anybody help?
Thanks,
David McDermott

Without dropping into python, I would suggest PointCloudCombiner to turn your raster into a point cloud, PointCloudSplitter (using the range you identify as green/grey) and then a PointCloudPropertyExtractor (don't extract any of the components) to get the number of points as an attribute.
Alternatively you could use the PointCloudFilter instead of the Splitter.
