US Patent 7610311 Method for quantifying plant resources using GIS

A method for quantifying plant resource using a GIS is disclosed, in which it is possible to more efficiently quantify plant resources with less manpower, time and cost using a GIS when quantifying plant resources in a certain region. In the method, a sample group is extracted from mother groups having a plurality of distribution maps having a plurality of environment factors including IMI as attribute data, the IMI being obtained through a GIS preprocess. A relative model formula is obtained between a plant resource real measurement value of the sample group and an environment factor real measurement value and is related with the distribution map of the mother group, and the distribution maps are overlapped for thereby forming a plant resource estimation distribution map of the mother group.
