A system includes a database and a representation engine. The database stores point cloud data including an indication of elevation of terrain. The representation engine is configured to determine a plurality of regions associated with the point cloud data. The representation engine is configured to identify, for each of the plurality of regions, a first point cloud data point having an elevation that is a local maximum for the corresponding region. The representation engine is configured to calculate, for a plurality of viewpoints corresponding to the point cloud data, a series of vectors connecting first point cloud data points located within a distance threshold of a search distance from each viewpoint. The representation engine is configured to output a terrain database storing the plurality of viewpoints associated with the corresponding series of vectors.
