First of all, the method for estimating the detailed population distribution data was developed for that. The residential area was selected by using the detailed digital information (10m grid land use data). And, the population of each small region unit was divided in proportion by the residential area, and population distribution data of 10m mesh cell was presumed. The distributed population was estimated from three kinds of residential areas by multipul regression analysis, and the value was corrected by the total population of each small region units.
Next, the population distribution map was used to estimate for the amount of resident in the area where water is recognized. And, the section of the waterway where the waterside function was high was clarified according to the totaled area population putting weight on the distance from the waterside. These values can be used to plan the waterside as an index when the necessity and the effect of the waterside improvement are evaluated.
