This is a survey package which can incorporate and mix most type of surveying used to determine boundaries for forest service units, or to navigate to sample plots associated with the units. The Forest Management Service Center, Forest Products Measurement Group, has successfully used this package in several forests exercises, experimental site tests, and academia arenas. This is a freeware survey package supporting NFS timber cruisers. Consult with your regional measurement specialist before using this program in production activities.
