Extract Roof Form Error 3d Solution

CliftonGreene — Mon, 16 Dec 2024 15:08:59 GMT

Hello,

I'm working on a project for school where I need to recreate a coloroized LiDAR point cloud and am using the Solution walk through. I have created the DEM, DSM, and nDSM but once I attempt to create buildings at the first step it fails after a few seconds and I cant figure out why. I think there may be a coding error that it keeps running into but I'm not sure how to soleve it.

Clifton,

We are glad you are exploring using this tool. From the error log it looks like you have an issue: "Shapefiles are not supported. Please copy to a geodatabase."

All of your data must be contained within a GeoDatabase for the tool to function properly. By default the paths are always set to create the data in a local geodatabase on your computer. Did you download the sample dataset and run the tools? That would give you an example of what the geodatabase would look like.

Let us know if this fixes your issues.

Thanks

Nick
