Storage and Application of Cartography and Database Integration Data Based on GML
摘要
Abstract
Traditional cartography and database integration has the problems of separation and different formats between cartographic data and basic data.Therefore,we established a cartography and database integration model to realize the unified storage,management and application of data.Firstly,GIS data were usedas the basic data,corresponding map scheme was established to form mapping data.GML cartography and da tabase integration model was set based on the unified storage and management of basic data and mapping data mentioned above.Then,relevant mapping information was extracted from GML geographical database;properties of GML geographic elements were analyzed.Map symbol informa tion was selected from map symbols bank.Map arrangement was realized by programming language and saved in GML database.Thus,integration storage of mapping data and basic data was achieved.Finally,with the land use data of development zone at county level as a case,GML database was applied.C# programming language was used to complete the GML storage of land use data.GML visualization was realized by the visual controls provided by ArcEngine;mapping output was carried out by the map function provided by ArcGIS Engine,so that the GML data application of cartography and database integration was realized.关键词
