Abstract

Using an IKONOS 1-m panchromatic image covering a range of forest ages, points representing individual trees were extracted via local maximum filtering. Nearest neighbour statistics were applied to the local maximum points and metrics representing forest structure developed. Point attributes, based on forest structure metrics, were then generated and used to aggregate the points into polygons. The resultant forest structure polygons show a meaningful association with nine age classes used by the British Columbia Ministry of Forest for forest inventory.
