C# 中SharpMap的简单使用实例详解

时间:2022-01-12 17:35:43

本文是利用shapmap实现gis的简单应用的小例子,以供学习分享使用。关于sharpmap的说明,网上大多是以shapefile为例进行简单的说明,就连官网上的例子也不多。本文是自己参考了源代码进行整理的,主要是winform的例子。原理方面本文也不过多论述,主要是实例演示,需要的朋友还是以sharpmap源码进行深入研究。

什么是sharpmap ?

sharpmap是一个基于.net 2.0使用c#开发的map渲染类库,可以渲染各类gis数据(目前支持esri shape和postgis格式),可应用于桌面和web程序。代码行数近10000行,可以算是一个实现了最基本功能的gis系统,有利于研究学习使用。

涉及知识点:

  • sharpmap的基本概念:layer(图层,常用图层:vectorlayer,labellayer) , iprovider(数据提供者,常用数据源:ogr(对应mapinfo),shapfile,datatablepoint(对应dataset))
  • 坐标转换:主要用于经纬度和地图坐标的转换。
