Resolution of raster builders
« on: May 18, 2021, 12:43:36 PM »
Hello !

We are struggling with resolution when building raster, starting with DEM.

Indeed, we are not able to set the resolution taken into account while building DEM.

Could you help us ?
Regards

Input :
Code: [Select]
chunk.buildDem([some_parameters], resolution=0.01)

Executed :
Code: [Select]
BuildDem: source data = Dense cloud, interpolation = Enabled, resolution = 0.01
generating 34799x33343 dem (10 levels, 0.0155608 resolution)

Hello Yoann,

resolution parameter is only considered, if mesh or tiled model is used as source.

If you are using dense cloud as a source, the default resolution will be used. After that you can transform DEM to the desired resolution or just use custom export resolution.
