How would You make a workspace that does this?
If it is fast and can do very large datsets it is definitely a big plus...

Hi @vgurra, there seems not to be an efficient way to do that in the current FME, but the PointCloudStatsRasterizer from FME Hub with a preceding PointCloudCombiner could be a workaround in the interim. Assuming the source raster has a single band representing a terrain model, after transforming the raster into a point cloud with a PointCloudCombiner, apply the PointCloudStatsRasterizer with these parameters.
- Component to Rasterize: z
- Statistics Calculation Mode: maximum
- X Cell Spacing: <x cell spacing for resampling>
- Y Cell Spacing: <y cell spacing for resampling>
Hope this helps.

Thanks a lot! I would not have found that solution myself.
