LiDAR in ArcGIS: The big Picture
• Visualisation- Las Dataset & Las Dataset Toolbar
• Analysis- Surface creation- Line of Site & Profile views
• Management- Mosaic Dataset
• Sharing- Via Image Service
Management and sharing
• Manage LiDAR like imagery via Mosaic Datasets
- Add / remove LAS files- Add / remove LAS datasets
• Share the data as Image services- Easy for others to see available LiDAR- Easy to download for project work
Best Practices for working with LAS in ArcGIS
• LAS Data- Tiled LAS, v1.1 or higher- If no .lasx present
- 200 mb file size limit (preferably around 50mb)- Keep file I/O local, avoid network
- If .lasx present- File size and network location considerations mitigated
- Projected coordinate system
• Airborne- Classified (bare earth, non-ground)- Breaklines for hydro enforcement- Study area boundary included as constraint
• Terrestrial- RGB, intensity
