Data Mappings: Buildings and Obstacles
Special Case: <Geometry Models>
- No attribution required
- Building Algorithm:
- Computes a roofline by finding all vertical or near vertical polygons (within ±15 degrees) and attempting to find a path that traverses along them to create a roofline.
- Obstacle Algorithm:
- Computes a simple bounding box by finding the x,y, and z extents, and encodes the top of the bounding box as the roofline. Useful for small obstacles (fire hydrants, signs, vehicles) and unusually shaped buildings that fail the building algorithm.
- When <Geometry Model> is associated to a <Point Feature> or <Areal Feature>, the feature is considered an alternate representation and processed instead.
