Hello,
I want to extract the roof forms of buildings using Lidar data and buildings of Amsterdam.
I followed all the steps of the Esri tutorial for extracting rooftops from Lidar data.
I created a all the elevations layers (DSM, DTM, and nDSM) following all the steps of the tasks.
After running the extract roof form I get an error
The parameters are as following:
- minimum flat roof area: 250
- minimum slope roof area: 75
- minimum roof height: 8
First, after running I got the error 000735 that said that the parameters are invalid.
After playing with the parameters and using other building data I got the error 010423.
Who can help me out?
Greetings,
Rens
Solved! Go to Solution.
The lesson Extract Roof Forms for Municipal Development has been fixed and updated for the latest software versions.
I am still getting the same error detailed in the original question while using the current Solution for extracting roof forms in my local area. Any suggestions?
Hi,
Could you share some of the data so I can debug?
Gert
Sure thing, and thank you for the quick response. It's 3 rasters (DSM,DEM,nDSM) and the building footprint. How would you like me to share them with you?
Hello,
Could you please tell me how you'd like me to share the files with you?
It's 3 Rasters and the footprint shp.
Thank you
Odysseas

Can you please send me an email on gvanmaren at esri dot com? Then I can send you an upload location.
Thanks Gert
Hi Odysseas,
I checked out your data. Couple of things:
Once you change that, it works. I will put some comments in the doc.
