Hi!

I'm trying to create a raster
based on high density point features (bathymetry data) from ArcSDE. The thing
is that I want to control which features enters the
NumericRasterrizer/RasterDEMGenerator (or some other suitable transformer) and gets assigned a cell
value. The problem is that the point data is much denser than what I want the
resolution of the raster to be. In this case I want FME to pick the point
feature with the minimum z-value of all the in-going point features and assign
it to the cell and ignore the others. Much like you have in ArcMap where you can can choose the "Cell assignment type" in the "Point to Raster" tool.

Is there a way in FME to solve this?

Thanks!

Hi @poseiron, this seems to be a case where the PointCloudStatsRasterizer (Statistics Calculation Mode: minimum) from FME Hub could be applied to. See this similar question.

How to keep maximum values when resampling a raster?

Thanks for the quick response! I will check it out

It worked! I also had to add a PointCloudCombiner and RasterBandInterpretationCoercer, but now i runs perfectly 🙂 Thanks for your help!
