Study Of The Provincial Basic Geographic Information Updating Platform

Full use of the existing basis GIS data resources, combined with digital maps, GIS mapping technology, to build the basic geographical information updating platform. not only meet the needs of topographic maps production, but also provide the basis spatial data for GIS. facilitate being used in the future for planning, resources management, environment for investment analysis, commercial distribution, and other areas.The purpose of this research is the integral production of the graphics data and the space data.how to make the production and the expression of the space data together, to realise the geography update and the DLG data at the same time.by one data collected process, get two kinds of data at the same time.the same set of data produced by the same workflow,we can get two sets of different data products at the same time, a set of geography data product that used for map graphics, the other set of DLG product used for GIS.Overview of the current development status and trends of cartographic technology and geographic information technology, pointing out the existent problem of the technique process in the traditional space data produces . Compare the differences between data mapping and geographic information, on the basis of studying spatial data, classification, coding, and other characteristics, Proposes a thought that the mapping data and the spatial data integrated production.This paper make a over-all design of the basic geographic information updating platform. elaborate the localization of the system, the demand analysis as well as the development way. From aspects of layer, attribute structure, essential object classification code and map, explain the data organization and the management of the basic geographic information updating platform. study the building of symbol library of the geographic information updating platform, designed and realizes the functional module of the basic geographic information updating platform.
