5.3. Correspondence of GIS 
and IKONOS analysis 
Figure 9 shows the extraction result of the 
overcrowdedness urban area by the GIS analysis on the 
town even number eyes and the overcrowdedness urban 
areas by the IKONOS analysis. Judging from the thing 
which came in succession roughly, it was able to be 
understood as the overcrowdedness urban area which had 
been obtained by the land coating classification of the 
overcrowdedness urban area extracted by the GIS 8 item 
with the town even number eyes in Figure 9 and the 
IKONOS image that the understanding with each town 
even number eyes was possible from this figure. As for a 
part within the range judged to be an overcrowdedness 
urban area from the IKONOS analysis, the value of the 
eternal resident population density is low in the factory 
area and the warehouse street. On the other hand, it is 
guessed that it did not agree because the district judged to 
be an overcrowdedness urban area from GIS is along the 
river, and the waters part influenced pixel ratio.

Moreover, the correlation analysis with the GIS item was 
done in the IKONOS analysis as well as analyzing TM 
(Table 5). A high correlation for the correlation coefficient 
to exceed 0.7 compared with the TM data was not able to 
be obtained in Table 5. However, because the IKONOS 
image is a high resolution in this, it is thought that the 
purpose is to have received the influence of the shadow of 
the structure. It will be able to be said that a high in some 
degree correlation is obtained if that is taken into 
consideration.

Nekozane , Horie , and 
urban areas in the Uraya 
IKONOS analysis as having already described. Figure 10 
is an aerophotograph which compares Nekozane Horie 
district and Kairaku district in the Urayasu City. As for the 
left Nekozane [1 Horie district made an overcrowdedness 
urban area, the town district shape can be also more 
complex than a right Kairaku district and the situation of 
the overcrowdedness urban area be understood well. On the 
other hand, right Kairaku district does by the readjustment 
of town lots by the shape of the town district in an orderly 
manner, and is not judged from which result of GIS and 
IKONOS as an overcrowdedness urban area though is an 
overcrowdedness ratio in a similar building.

6. Result and View in the future 
In this research, each of the utilities were examined aiming 
to make out the situation of the overcrowdedness urban 
area in the Tokyo Bay area in the pattern by using the TM 
image and the IKONOS image by an analytical technique 
Which centered on the land coating classification. The 
population, the home, and the situation of the open space in 
the forest etc. as city information were able to be 
understood by understanding pixel density of the urban 
area and the green tract of land in each municipal district in 
the TM image analysis. 
Moreover, the finding that situations of the fire breaking 
out number etc. were able to be guessed was obtained from 
the relation of GIS. Moreover, the method of understanding 
the situation of the overcrowdedness urban area in the 
outline in each municipal district was able to be obtained 
by measuring the distribution situation of these pixels. 
Moreover, because it was a high resolution, the road and 
the town district shape, etc. were able to be understood
