问题 Is there a way to find out what polygons (specifically circles) a specific Point lies in? In this case I would have stored a documents containing circles, like below, I would pass in a latitude and longitude for a point, and would like to get back all documents where the point is within the given circle. { "_id" : ObjectId("53e3e85ce4b0c2e8227a1dad"), "name" : "Menlo College", "location" : [-122.1928, 37.45632], "radius" : NumberLong(215), }, { "_id" : ObjectId("53e43d19e4b0aeabcb3d3f9d"),

Loading a geoJSON object directly into google maps v3

由 时间秒杀一切 提交于 2020-05-09 19:26:31
问题 I'm trying to create a map, using floor plans that I've stored in mongodb. If I put the JSON into a file, I can call it using map.data.loadGeoJson('myfile.json') However, I don't want to save a file each time I build a map, and I'd rather write an object directly. Something like this: var tempObject = { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": { "letter": "G", "color": "blue", "rank": "7", "ascii": "71" }, "geometry": { "type": "Polygon", "coordinates": [

node-mapnik制作瓦片地图简单实现

由 北城余情 提交于 2020-05-07 13:33:17
node-mapnik安装过程略，我们使用geojson为数据源，也可以使用其他的数据源，这里为了简单 直接上代码point.json { "type": "FeatureCollection", "features": [{ "type": "Feature", "geometry": { "type": "Point", "coordinates": [ 113.44397, 23.094416 ] } },...] } 编写mapnik.map 需要用到的tile.xml <Map srs="+init=epsg:4326"> <Style name="light"> <Rule> <!-- 点样式，默认黑色--> <PointSymbolizer file="../img/mass1.png" transform="scale(0.1)" allow-overlap="yes" ignore- placement="yes" /> </Rule> </Style> <Layer name="lightlayer" srs="+init=epsg:4326" > <StyleName>light</StyleName> </Layer> </Map> 瓦片需要用到x,y,z三个参数，使用mapnik自带类转换,也可以用自定义类转换来实现特殊瓦片 例如百度
