Point Cloud - DEM raster generator from highest point - problem with holes


Dear all,

Task: create DSM raster from point cloud with highest points in each cell 0.5 x 0.5m

 

I tried with RasterDEMGenerator - but it's not taking the highest point in each cell.

 

PointCloudStatsRasterizer receives good values, but i got holes. Is any tool to close gaps in raster, like SAGA GIS - close gaps?

 

From LASTOOLS.lasgrid i received also holes:

 

Or maybe any idea more?

 

Thanks for help in advance

Hi @marekszczepan, how about applying the RasterDEMGenerator to the resulting raster output from the PointCloudStatsRasterizer (Mode: maximum)?

Hi @takashi,

 

 

of course You are right. It helps

1) PointCloudStatsRasterizer (mode:maximum)

2) RasterDEMGenerator

I tried too many things.. my mistake

 

 

Thank You for help :)
