TSC has developed a tool that automatically extracts buildings and trees, from high-density elevation data. This tool has the capability to automatically extract building footprints and heights from a Digital Elevation Map (DEM), and draw 3-D building models in OpenFlight® format (other formats such as shapefiles are available).

Using TSC’s Automated Feature Extraction Tool a database builder can expect:

· An accurate height associated with each building model
· Automatic drawing of complex shaped buildings
· Feature extraction on sloped areas
· A “confidence” attribute with every building drawn
· Automatic extraction of trees
· Output of a bare Earth DEM

Using a tool to automatically determine building footprint and height can save time and money when creating large-scale databases. The Automated Feature Extraction Tool can be packaged as a stand-alone application or as a plugin to existing database creation software.
