MapWinGIS是一个不错的开源GIS项目，开发语言是VC，基于微软的COM思想编写，团队的开发人员主要来自美国爱荷华大学，开发团队中还有一位中国人。系统来讲，MapWinGIS是一套类似于AO的二次开发组件库（只是没有AO那么强大），其核心库是一个名字为MapWinGIS的ActiveX控件，开发人员可以利用这个ActiveX组件在自己的系统中添加GIS的相关功能，例如地图显示；在图层上标绘点，线，图形；计算长度，存取GIS数据等相关工作。ESRI在AO的基础之上开发了ArcGIS的桌面产品，类似的，他们也在MapWinGIS 这套组件库的基础上，二次开发了MapWindow GIS,这是一套桌面GIS系统，相当于一个简化版的ArcMap，桌面GIS系统的开发语言使用的是VB.NET。用户可以直接通过它浏览数据，并通过一系列插件来完成其他功能。还有一套MapWinX，是DOTNET平台下的一个辅助工具。(The objective of this series is to present a simple and easy to use approach to develop a desktop GIS application. My tool pack includes only MapWinGIS.ocx from MapWindow GIS Project which is one of the most successful open source GIS projects for Windows platform. MapWinGIS.ocx provides the full set of tools to maintain and display GIS data and it is free of charge under MPL license. In the previous lesson, we discussed the basics required to display GIS data on the MapWinGIS.ocx Map Control. We also discussed how to customize the symbology of the displayed GIS data. In this lesson, I am going to teach you how to advance your symbology skills and use labeling functionality on your map. As mentioned in the previous lesson, I am using .NET Framework 3.5 and Visual Studio 2008 professional edition in the code attached here, but you can use Visual Studio express edition to get the same results. You have to download MapWinGIS.ocx and install it on your machine too. You can download i)
