1. Background and purpose of research 
It becomes an age when a continuous measurement and 
the watch of the city environment intended for the large 
range are necessary along with the diversification and 
extending the city environment. It is necessary to consider 
a lot of problems that the city has in doing the urban 
renéwal enough. Properties of the city environment are

n In this research, to understand the district 
characteristic of the city in pixel distribution situation by 
the remote sensing analysis and the relation to the GIS data, 
the following research developments were done. 
2 Selection of district for investigation | 
In the selection of the district for the research, 1 capital 
and 3 prefectures (Tokyo, Saitama Prefecture, Chiba 
Prefecture, and Kanagawa Prefecture) in the 
overcrowdedness urban area which it was a lot of regions, 
and was the populous districts were in the Tokyo Bay area 
were paid to attention, Mainly the central area of Tokyo, 
the region where the development act was remarkably done, 
and the following 57 municipal districts were selected in 
that in consideration of the influence on the city to the flow 
of the change in the city environment and the population.
