基于DotSpatial的组件式GIS开发与应用

摘要

Under the developing environment of C# and component technology,combining with Visual Studio 2010 as a system interface development and calculation module programming tool and developing secondly by DotSpatial components ,the paper ifnished the Expressway of Hainan Province Expansive Soil Management Information System initially based on open source GIS,it implemented the functions of Expansive Soil Map of Hainan Province Highway,such as map browsing and editing, information query, data management, spatial analysis, and so on, the visual effect is intuitive and efifcient.Thereby,it provides the basis for the management of the engineering construction, expansive soil disasters prevention, early warning decision-making.%采用C#和组件技术相结合的开发环境，以Visual Studio 2010作为系统用户界面开发与计算模块编程工具，基于DotSpatial组件进行二次开发，初步形成了基于开源GIS的海南省高速公路膨胀土地理信息系统，系统实现了海南省公路膨胀土分布图的浏览编辑、信息查询、资料管理、部分空间分析等功能，具有直观、快速的可视化效果。为工程建设的管理及膨胀土灾害防治和预警决策提供依据。
