Abstract
Systems and methods are described for adjusting planar geometry derived from point cloud data associated with a building object by identifying major aspects like vertices and edges of the underlying structure within the point cloud and adjusting an average planar fit for simplified geometries created from the point cloud. Combining the planar geometry or point cloud with orthogonal or street level views improves accuracy and use cases of the planar geometry.

A method of modeling planar surfaces, the method comprising:
- receiving a three dimensional point cloud of data points associated with a building object;
- identifying a plurality of vertices defining edges of at least one single planar surface of the building object within the point cloud;
- outlining the at least one single planar surface based on the identified plurality of vertices;
- creating a simplified façade geometry for the at least one single planar surface based on the outlined single planar surface;
- correlating data points within the point cloud to the outlined single planar surface;
- averaging a planar fit for the outlined single planar surface based on the correlated data points;
- and
- adjusting a position of the simplified façade geometry based on the average planar fit.
