Toolbox location Placed under Toolboxes in ArcCatalog

LAS File Information LAS file version, point format Num points XYZ extent Spatial reference Returns Class codes Etc. Written to text file next to LAS

Create PRJ For LAS Add or override spatial reference for LAS files Creates sidecar PRJ Similar to shapefile or image Easily create multiple PRJ for folder full of LAS

Classify LAS Overlap Points Finds points in overlap areas of flightline swaths in aerial lidar Requires Point Source ID, representing flightline number, to have been set by the data provider Points with larger scan angles in areas of overlap will be classified as overlap. Thus higher accuracy points are preserved.

LAS Building Polygon Works on lidar with building/rooftop points classified Finds ‘clusters’ of building points and aggregates them into polygons

Canopy Peaks Uses a raster Canopy Height Model (CHM) as input. This is same as a normalized DEM (nDEM). Finds local highs based on areas that vary in size based on height. Assumption is the taller the tree, the wider its crown. Works best for coniferous forest where trees have more clearly defined peaks

Updates in Pro and other ArcGIS Apps Create PRJ For LAS is option on Create LAS Dataset tool LAS To LAS is available as Extract LAS Enhanced to support irregular clip boundary polygon Rearrange LAS is option on Extract LAS tool Classify LAS By Height, Locate LAS By Proximity, LAS Point Statistics By Area added to Pro 1.0 and ArcGIS 10.3.1 Classify LAS Ground in Pro 1.2 and ArcGIS 10.4
