I have LAS data obtained from 2014 NCFMP Lidar: Statewide North Carolina (Phase 2). I've created LAS dataset in ArcGIS and was trying to extract building footprints using LAS to Raster tool (I filtered classification codes first). However, when I ran the tool it displayed an error 'ERROR 999999: Error executing function. No spatial reference exists.' I've looked at metadata and horizontal coordinate system seems to be correct while vertical should be NAD83(2011) Ellipsoid (meters) and in properties of my LAS dataset it displays as Custom NAVD88 height. I reassigned to NAD83, but it didn't change anything and I'm not sure how to fix it otherwise.
I also opened my data in ERDAS Imagine to double check, and, indeed, elevation information was shown as undefined.
I'm new to LiDAR.
I've attached screenshots in case it'll be helpful.
Process Description: Data were received by the NOAA Office for Coastal Management from the North Carolina Flood Mapping Program in the form described above. It was ingested into the Digital Coast Data Access Viewer system for distribution by:
1) reprojecting to geographic coordinates with vertical meters
2) transforming the vertical datum to NAD83 ellipsoid heights using the NGS GEOID12a model
3) compressing the data using laszip (LAStools version 150828) to LAZ format.
