I have been generating content for the World Topo Map Basemaps including the Contours, Spot Elevations, Vegetation and even buildings from Lidar. This blog will be dedicated to feature extraction from raster or point clouds to vector. : Issue found with Clean Extracted Buildings Using Regularize Building Footprint Tool not working if there are no large buildings (over 25,000 sq. : Corrected error in models for Clean Extracted Buildings Using Regularize Building Footprint Tool due to bug in Regularize Building Footprint tool (inputting empty featureclass). : Added Clean Extracted Buildings Using Regularize Building Footprint Tool : Changed 1200 to 12000 in the Regularize Building Footprint tool suggestions. : Added extensively to the Regularize Building Footprint tool suggestions.
This replaces the methodology with Geoff Taylor showed in Extracting Building Footprints from Classified LiDAR using some of my older techniques. This covers Extracting Building Footprints from Classified Lidar for buildings, Extracting Building Footprints from Unclassified Lidar for Buildings, and the 3D Basemaps for taking the footprints to 3D and adding trees. : Please see 3D mapping with Lidar Point Clouds, this are ArcGIS Pro Tools, example data and workshop exercises from the IMF workshop we developed for this year's Imagery and Mapping Forum before the ESRI UC. For creating 3D buildings from the extracted 2D building footprints, please use the latest version of the Local Government 3D Basemaps solution. These updates will eventually be applied to the 3D mapping with Lidar Point Clouds.
These tools are improvements that I have tested with many cities/counties for building extraction. This fixes issues with the Unclassified approach to building collection from lidar, a tool to clip buildings extracted to parcels, and Jagged tool which help to identify jagged buildings that come as a result of regularization. : Added an update to the tools in the 3D mapping with Lidar Point Clouds below called ArthursLidarBuildingExtractionTools_10_04_2018.zip. : Added link and instructions to create 3D buildings using lidar from Microsoft Building Footprints US. : Added how to make a tree inventory 3D without lidar or height (hint DBH).
