TOPOLOGICAL MODELING

BNB can recognize and analyze the spatial relationships that exist within digitally stored spatial data. These topological relationships allow complex spatial modelling and analysis to be performed. Topological relationships between geometric entities traditionally include adjacency (what adjoins what), containment (what encloses what), and proximity (how close something is to something else).

• Reconstitute a sight in synthesized images of the ground
• Determine a trajectory of over-flight of the ground
• Calculate surfaces or volumes
• Trace topographic profiles
