2.4 Characteristics of Information 
Main purpose of establishment regional land information 
land is to investigate trend of housing area at the largest 
urbanized regions so that it is necessary to take care for its 
data classification standard, details and accuracy. 
It is more effective for the larger area than local city, 
town, village unit. 
As the result of this examination, obvious data error was 
recognized in some part and noises were found in other 
part. However almost of these data errors was proved to be 
no effective for its data analysis.

4.Land Use Trend Analysis 
The land use ratio, mixture and continuity with unit of 1km 
mesh area in each sub-test site were used for investigating 
of the regional land use trend. 
4.1 Land Use Ratio 
The land use ratio was used for understanding the resent 
status for mentioned four target areas. 
Fig.1 shows the land use ratio in each sub-test site. Area-A 
Ratio of natural land use such as forest, paddy, etc., is 
extremely low because of existing urbanized area. On the 
other hand, the ratio of residential and commercial items is 
comparably high. Trunk road network is not completed 
because of low road ratio. 
In Area-B, Agricultural residential, commercial items have 
the same ratio as each together other land use area was 
equally occupied because there are many housing 
developments in agricultural area. 
In Area-C, under constructing trunk road networks as the 
typical planned development area. 
The residential items, park, public utilities are mostly 
occupied.
