Description

Reseach on the land use investigation using satellite data is being carried out very actively. We have developed “Latency Factor (LF) model” for the land use capability classification and evaluation. Points to which special attention should be paid are that satellite data and geographical information are defined as latency factors in the land. LF model doesn't evaluate a value in use of the land but a potential value or a value of existence in the land. The analysis processes are as follows: 1) Quantification Method Type III are used to analyze the causality between latency factors. 2) The land use capability classification map is made by Quantification Method Type II and the min-max method distinguishing areas resembled training data.<br>Furthermore. LF Model has the three evaluation processes called “Present situation type”, “Normative type” and “Hypothetical type”. By comparison of classification maps of the farm land made by LF model and the former grading method. LF Model is very useful for extracting appropriate areas.
