Generating a DTM from LiDAR

GISOffice — Mon, 09 Apr 2018 19:47:34 GMT

I am using ArcGIS Pro to generate a DTM from LiDAR and the I am getting the following result. I verified the projection and ran statistics while creating the LAS dataset. When exporting my ground points to raster, the process appears to run, but my elevations do not look right and the data is not displaying in the map. I do not have any ideas as to why this might be occurring. I've performed the same process in Pro and in ArcMap 10.5.1.

Which geo-processing tool you are using for DTM creation from LAS? The snap you attached is showing a no data raster, means the raster created with no value.

Following are the steps that I follow:

- Verify the LAS dataset has the ground class with proper classification.

- Make a LAS dataset layer to only select the ground points.

- Run the LAS Dataset to raster tool and specify a 'value field' as 'Elevation'. Also use the 'Sampling Type' as 'Cell size' and specify the 'Sampling value' as the DTM resolution need to be used.

This should make you DTM. Please let me know the outcome.

Thanks & Regards
