Theoretical Research And Application Of Urban Infrastructure Information Managing System

Roadway and kinds of undempund pipes are important Infrastructure ofa city and are material foundation on Which the living and development of acity depends. But the datum on foundmaintain of city is not dependable,which cause lots of problems. This article aimed at solving this problembased on the technology of GIS, which has developed to a higher level thanpast.This article introduced the researching actuality. technique background.characteristic and aPplication of GIS firstly. Secondly it introduced thedesigning frame of UIIMS, achieving of the sub--function and the pattem ofthe application. It emphasizes on the principle of the map digitizing, thefoundation of the data model and encoding means, the construction of thetopology data structure, the theory of different fOrmat data convertion.We impolder Fuxin Infrastructure InfOrmation Managing System basedon the GIS theory. This system has the following functions f digitizing map,Editing map; Space querying; Space analyzing, Arbitrary map output,Section analyzing.This system not only the first in Fuxin, but also can avoid unwantedeconomic loss and provide gist for the building of city. Therefore it can bringgreat benefit on economy and soviet. It also the first step of Fuxin towards"Digital City".At last of the thesis the sumrnarize and prospect are made on FIIMS.
