Classified Tiles Metadata. The raw project LiDAR data was imported, processed, and outputs were created using the TerraScan software suite. Automated ground filters were run on the raw las data. These filters include factors and settings such as max building size, terrain angle, iteration angle degrees to plane, iteration distance to plane, reduce iteration angle when edge length is less than, and stop triangulation when edge length is less than. After the automated ground filter is run each tile is than checked for spikes and anomalies. Manual edits are applied to any areas that the analysts interpreted the ground doing something other than what the automatic ground filter interpreted. An analyst also classifies and edits any other las point to needed feature classes at this time. Only the LAS inside the provided map limit was classified and checked by analysts. Any points that were relevant to the classification were classified to the SOW requirements and placed using the classes provided in the SOW. Class |
