geojson格式数据

可以通过一下地址验证

https://geojson.io/#map=11.2/38.2756/116.7917

一个面数据的情况，

features是一个数组，geometry 的type=Polygon表示一个面数据，可以存放多个面数据，以下就存放了一个面

{
       "type": "FeatureCollection",
       "features": [{
           "type": "Feature",
           "geometry": {
               "type": "Polygon",
               "coordinates": [
                   [
                       [100.0, 0.0],
                       [101.0, 0.0],
                       [101.0, 1.0],
                       [100.0, 1.0],
                       [100.0, 0.0]
                   ]
               ]
           },
           "properties": {
               "prop0": "value0",
               "prop1": {
                   "this": "that"
               }
           }
       }]
   }

　　

geometry 的type=Polygon，存放多个面

{
       "type": "FeatureCollection",
       "features": [{
           "type": "Feature",
           "geometry": {
               "type": "Polygon",
               "coordinates": [
                   [
                       [100.0, 0.0],
                       [101.0, 0.0],
                       [101.0, 1.0],
                       [100.0, 1.0],
                       [100.0, 0.0]
                   ]
               ]
           },
           "properties": {
               "prop0": "roger"
               
           }
       },{
           "type": "Feature",
           "geometry": {
               "type": "Polygon",
               "coordinates": [
                   [
                       [102.0, 2.0],
						[103.0, 2.0],
						[103.0, 3.0],
						[102.0, 3.0],
						[102.0, 2.0]
                   ]
               ]
           },
           "properties": {
               "prop0": "james"
               
           }
       }]
   }

　　

geometry 的type=MultiPolygon，存放多个面

{
	"type": "FeatureCollection",
	"features": [{
		"type": "Feature",
