The forest forecast map based on system yield table : Spatial retrieval and forecast

Abstract

This paper introduces a system which can provide more practical spatial information by using system yield tables and GIS (geographic information system) for forest resources management. This system utilizes functions of growth and yield forecast in the system yield table and spatial retrieval in GIS, to realize the generation, search and output of forest forecast maps. In addition, the procedure for generating forest maps on the basis of system yield tables and GIS is provided. The method introduced in this paper may be useful for strengthening the function of system yield tables in forest management.
