I am using ArcGIS and have access to Spatial and 3D Analyst extensions.
I've attached a link to a picture of a 1m raster “canopy height model” which was derived from LiDAR and displays tree heights (in 5m intervals but can obviously be adjusted). I do 3d models w/ a program that uses polygon inputs to derive height classes.
How can I convert this raster to a polygon and capture broad polygon classes?
(I can’t use raster to polygon as I work with 100’s of hectares at a time and an individual polygon for each raster cell would be far too much detail and slow the program down.)
I’m thinking of a heat map (?) type exercise which captures general trends as polygons. I’ve circled several polygons in blue that would be the ideal type of polygons I would like to capture…but ultimately I do need 100% polygon coverage.
I have access to SA and 3D analyst if that helps! In terms of accuracy, I'm not sure. As accurate as I can be without having 1m polygons or anything too small.
