基于ArcEngine的陕西省土壤信息系统构建

Establishment of Shaanxi Soil Information System Based on ArcEngine

土壤信息系统的构建对于充分利用土壤资源,实现土壤资源的信息共享具有重要意义。以陕西省为例,采用Geodatabase模型和Access数据库分别建立了空间数据库和属性数据库,并结合ADO.NET技术,基于ArcEngine9.2组件在VS2005.NET环境框架中设计和构建了陕西省土壤信息系统。该系统具有图层管理、数据管理、输出管理、空间分析、专题评价等功能模块,对陕西省土壤信息化具有实践意义。

The establishment of soil information system is of great importance to soil information sharing and utilization. By taking Shaanxi Province for an example and using Geodatabase model and Access, the spatial and attribute databases were established respectively. Based on the ArcEngine 9.2 component and combined with ADO. NET technique, soil information system of Shaanxi Province was developed in VS 2005. NET en- vironment. The system has several function models such as layer management, data management, output, spatial analysis, and evaluation models. The establishment of the soil information system is of great signifi- cance for soil informatization and decision-making of Shaanxi Province.
