Rasterize - best fit plane

Post by Vit »

Hi, would it be possible for the Rasterize tool to calculate the cell height from the best fit plane? In the case of resampling the input cloud, the height would correspond to the position of the point on this plane. Or there is another trick for that. Thanks. Vit.

You can export the raster as a cloud, and then fit a plane on it, and eventually compute the distances to this plane?

Hi, thanks for the reply. I need to calculate the best fit plane for each cell in the raster separately and derive the height of the raster point from it. Simply add the best fit plane option to the cell height options: maximum, minimum, average, median. It would be beneficial for decimation of ground surfaces. The mean or median is skewed by the distribution of points in the original cloud. Especially with sparse clouds or at the edges.
Thanks.

Ah ok, understood.

Someone would need to add that to the code.
