摘要: The database is the basis of environment management information system, with spatial data and associated attribute increasing continually, realization updated dynamically taken as core issue must be resolved urgently. Adopting component object model geographic system(GIS), such Map Objects, using connection technology, function has been come true to add environmental promptly relational on VB platform. Taking map rendering methods, visualization can realized by generating thematic maps, integration among database, databases fulfilled in order avoid a large number entered result redundancy.
