将lat long转换为geojson对象

Question

How can i convert my lat and long value into geojson object. I work on php platform.

Answer 1

If I understand well, you want to build a string like this:

$my_geoJSON = '{ "type": "Point", "coordinates": ['.$longitude.' ,'.$latitude.'] }';

As as the specification for GeoJSON format ( RFC7946 ) says:

Point coordinates are in x, y order (easting, northing for projected coordinates, longitude, and latitude for geographic coordinates):

  { "type": "Point", "coordinates": [100.0, 0.0] } 

Answer 2

Put all your Lat Long data in a CSV file and use the below online tool to create a GeoJson file. Verify it using http://geojson.io/ tool.

我想，你应该看看geojson规范（http://geojson.org/geojson-spec.html#id9），你也可以查看简单的例子，它肯定会帮助你用lat / lon创建一个简单的geojson 。
