Tools for handling large topography data sets

I’m working with large topography data sets and need to generate a fitted surface across a point cloud. The first challenge we face is decimating the data while retaining critical features. The number of points is just too large for a surface fit (processing time very long)

Are there any toolboxes, addons, or script toolsets available within Rhino aimed at working with topography data? I understand this is a very broad question, so I’m thankful for any first hints you can give me to start reading up on existing capabilities before re-inventing the wheel.


Hi @srechenb

is quite good.

or use geotiffs in combination with the Heron plugin (package manager)
