Name: Tree Canopy
Display Field: Value
Type: Raster Layer
Geometry Type: null
Description: This 1 meter raster is derived from PAG's 2008 LiDAR based ndsm and from a NDVI extracted from the 1 meter 2007 NAIP imagery. A threshold was identified for the ndvi surface to reclassify the surface to only represent vegetation with a value of 1 and non-vegetation was not classified. The ndsm is generated by subtracting the LiDAR based bare earth surface from the first return surface to get a "height above ground" surface. These surfaces were multiplied against each other to assign a height above ground to the vegetation cells. This surface was then reclassified into the following height category groupings: 1: 0ft-2ft above ground, 2: 2ft - 6ft above ground; 3: +6ft above ground.
