基于ArcObjects和ArcSDE的地理数据分发的实现——以云南省基础地理信息空间平台数据分发模块开发为例

Design and Realization of Geographical Data Based on ArcObjects and ArcSDE─By an example of Yunnan Province Basic Geographical Spatial Information System's Data Publishing Module

如何高效快捷的实现基础地理数据的分发是许多基础地理信息单位关注的问题。ESR I的ArcOb jects组件库提供了强大的G IS应用处理功能,结合ArcSDE空间数据库引擎可以实现一个实用的地理信息分发平台。在深入分析ArcOb jects和ArcSDE的基础上,结合VB6.0的组件式二次开发和O rac le9 i数据库,提出了一个地理数据分发的解决方案,并在云南省基础地理信息空间平台项目中得以实现,达到预期效果。

How to realize efficiently publishing basic geographical data is thought by many basic geographical information corporations. The ArcObjects of ESRI provide powerful GIS functions. When combined with ArcSDE （ Spatial Database Engine）, we can use them to realize an applied system of publishing geographical data. In this paper, the authors analyzed ArcObjects and ArcSDE, and using VB6.0＇ s the second package GIS and Oracle9i data system, gave a scheme of the problem, and it was successfully realized in the program of Yunnan province basic geographical spatial information system.
