Yes, so you can see that the bounding box along X and Y is super small (<0.02) and super large along Z (> 420).

This is once again typical from a geographical coordinate system. You can try to rescale X and Y with the 'Edit > Multiply / scale' tool (by using a factor of 100 for instance for X and ...

Oops sorry, here you are. Thanks.

There's good chances that Quick Terrain Modeler does manage properly geographic coordinate systems...

Looks like this.

here's what I see when importing. For some reason I don't have an issue when opening up this point cloud in Quick Terrain Modeler.

Hello, I'm not exactly sure what type of files you are using, but to give you a hint, I have encountered this type of issue before with files where the X, Y, and Z columns were not properly aligned. Make sure that the XYZ coordinates are correctly pointing to the appropriate columns in the table ...

Thank you. How can I check or edit this upon import?

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 ...

Hello,

Is there anyway to export my rasterized point cloud as an ESRI ACII Z Grid text file? It has the format of the attached screenshot.

Thanks.

Well just an idea,

1. Export the two cloud Z coordinate to SF
2. Flatten the two cloud by setting Z coord to zero (create a new SF with static zero, then set coordinate from sf
3. Interpolate one of the cloud Z sf to the other one ( do not overwrite original.
4. Interpolate one of the cloud Z SF ...
