3D Building Reconstruction

Extract more from your airborne LiDAR

Traditionally used for forestry, coastal management and the mining industries, today LiDAR is rapidly gaining more prevalence in the geospatial industry as a fast and cost-effection solution for capturing and creating 3D building models for urban planning and environmental simulation modelling.

LiDAR as a technology has advanced significantly in the last years and as a result the price for data capture is more affordable than ever. Read below to find out how virtualcitySYSTEMS can help you better leverage your LiDAR data; for more information consult our FAQ.

Best Practices for LiDAR data acquisition

3D building extraction

Advantage

1/10 of the processing time required by photogrammetric methods for feature extraction (3D buildings)

Automatic creation and file export of building topology (link to topology jpg as pop-up) from LiDAR data: roof, wall, ridge and eaves heights

Creation of LoD2 buildings with roof forms for large-scale projects (link zu case studies)

BuildingReconstruction vs. Photogrammetry for 3D Building Geometry: A Comparison

Photogrammetry		airborne LiDAR
1. Lower data capture costs, higher production costs		1. Higher data capture costs lower extraction costs
2. Automatic & semi-automatic processes		2. Automatic feature extraction, manual editing
3. Slow production cycle		3. Faster project completion
4. Delivers only building geometry		4. Geometry + building attributes (3D topology)
5. Average 10-15cm accuracy		5. Within 1 meter accuracy

Value Added: More Services and Deliverables

• Building footprint/cadastre map creation upon request

• Attributed building topology for roof slope and orientation

• Optional building model delivery in CityGML
