Problem to include attribute names when doing LAS to multipoints

NinaMichael — Sat, 25 May 2024 09:56:41 GMT

Hello, I have a proble when I use the tool LAS to multipoints. I want that my final multipoints layer keeps the attribute names "Classification" in order to be able to filter the layer and make appear only the vegetation. But even if I precise the attribute I want to keep when using the tool, the final layer doesn't have any field with the classification, so the attribute wasn't taken in account during the process I think. Do you have a solution? Or do you know another way to export the layer in my geodatabase with all the attrivutes conserved?

Best regards,

One workflow you could try is to extract each class individually from the las dataset and create multiple multipoint datasets by class: Filter las (one class at a time)>extract las (extracts a new las file with only one class)>las to multipoint. You will end up with one multipoint feature class per lidar classification. If you need the multipoints all in the same dataset, you can add a field in the multipoint datasets and populate it with the classification, then merge/append all the data back together.
