Poisson Surface Reconstruction Vs Rasterizing

[LiDoom]

Hello,

I am trying to understand the difference between using the poisson reconstruction tool and the raster tool. I have generated two separate point clouds (ground and non-ground points) using the CSF filter and my goal is to create a bare earth model using the ground only point cloud points. Which is the best tool to use to do this?

Well, the Rasterize tool is to create rasters (geotiff), which is quite different from a TIN/DTM represented as a triangular mesh (what you would get with the PoissonRecon or more simply with the Delaunay 2.5D meshing tool).

Also, most of the mesh formats don't handle large coordinates (contrarily to geotiff rasters). So if you have a georeferenced cloud as input, you'd better choose the raster.

So in the end it all depend on where you will import this data?
