Openscales2.2 mapserver 开发demo

很简单的一个地图demo，使用wms画线，请求wfs画点（ 其他的就不详述了，已经有很多文档了）。

map文件如下：

map

  SIZE 400 300
  IMAGECOLOR 242 232 106
  IMAGETYPE PNG
  STATUS ON
  EXTENT -180 -90 180 90

  PROJECTION
     "init=epsg:4269"
  END

  SYMBOL
    NAME 'circle'
    TYPE ELLIPSE
    FILLED TRUE
    POINTS
      1 1
    END
  END

 TEMPLATE就不在这里罗列了，参见mapserver官网有现成的。

在vs2010中增加openscales包的方法如下：

   鼠标右键你创建的flex工程，如下图：

 选择下载的openscales的开发包目录即可。

 在实际调用地图的过程中，可能会有跨域访问的问题，在你的地图服务（即Apache）下面增加一下xml文件：crossdomain.xml，内容如下:

<?xml version="1.0"?>   
<cross-domain-policy>   
 <allow-access-from domain="*" />   
</cross-domain-policy>  

　地图运行效果如下：
