The Design And Realization Of Data Editing And Updating Basing On Mapinfo

In recent years, uith the extension and popularization of system data making, the usion of GIS data basion on Mapinfo, Tab format in all kinds of trades is getting more and more popular, such as information inguiring analysing. As time goes by, the first gronp of GIS data basing on Mapinfo have changed much in surface features and physiognomg. With the high development of infrastructure and moderniza tion. Because of the limition of the former data structure design, the data attribute structure and data closenese must be updated, enlarged ang modified. And the data timeliness requires that the data must be frequently updated, according the changed surface features. As we all know, the data timeliness. has a direct offct on the use efficiency, but there is not ang special system software aimed at it. So this software is spedally used for system data updating and making.The artide chiefly introduces GIS data editing and the updating and Checking of data automatization and massness using MapBasic,under the given basic though. Taking the updating of 1:10000 GIS data of state basic surveging & mapping Item, Tianjin city, in the light of actual requirement in the production practice, it systematically expatiates programing method and basic thought of editing,updating and checking of data, It also introduces the generall flow of data editing, updating and checking and some programing technique. Of how to realize concret functions. And it discusses how to strengthen the function of geaphics editing, automatically add the attributes, updata·data· and massly ·check·data, using Mapinfo menu file and Mapbasic. And at the same time, it discuss the general method of the second programing basing Mapinfo.
