Finally, this paper specifically tells about the whole development progress of Estate Base Survey System.This system adopts Visual Basic 6.0 visual development tool, data terrace of Desktop Arcinfo to develop, huge database management tool Oracle to preservate great geography data, American ESRI' s ArcSDE for Oracle as GIS server, and it is based on the mode of Client/Server. Not only it can achieve some routine functions such as map display, zooming in, zooming out, panning, but also can it achieve these functions of all sorts of data export and inport, map attribution and spatial information' s editor and query, layer management, system management, map historybackdating, map print and output and so on. |
