I have vector data representing forests/trees/buildings that have been automatically extracted from LiDAR data. I am looking for specification/guidance for LiDAR derived products, or any standard for defining these features. For example, a forest is only a forest if it is larger than x square meters, or a tree is not a tree unless it is x meters tall, etc. The automatic process has created detailed features, and as a result very large datasets. I would like to find a standard definition so that I can thin the datasets. Ideally, I would like to know if there are standards developed/adhered to by the USGS, USDA, NGA, NFS, etc. Does anyone know of such standards/specifications? Thanks in advance.
EDIT: Process is similar to this.
