Convert lat long into geojson object

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.
