[ 服务说明 ]

intersection接口，提供几何对象的相交操作，如线对象与面对象相交计算，面对象与面对象相交计算。

[ 参数说明 ]

参数 参数说明
geo1 参数作用：点，线，面等几何对象的geojson结构描述
参数说明：
            {
              "type": "LineString"|"Point"|"Polygon",
               "coordinates":[<geometry>]
            }
参数示例：
            {
              "type": "Polygon",
              "coordinates":[[[110.22193718749995,39.880950312500005],[99.76295281249995,35.837981562500005],[111.18873406249995,29.246184687500005],[110.22193718749995,39.880950312500005]]]
            }
geo2 参数作用：点，线，面等几何对象的geojson结构描述
参数说明：
            {
              "type": "LineString"|"Point"|"Polygon",
               "coordinates":[<geometry>]
            }
参数示例：
            {
              "type": "Polygon",
              "coordinates":[[[108.221,40.9],[99.762,35.8],[120.1887,29.2],[108.221,40.9]]]
            }
format 参数作用：指定返回结果的格式
取值范围：html | json，该参数默认值为json
callback 参数作用：Ajax客户端使用JSONP方式进行跨域处理时所指定的回调函数名称
参数说明：可选参数，该参数仅在format参数值为json时有效
