Import a point in geoJson format into mapbox map with different coordinate system

Question

I'm using the mapbox.js API for building some kind of spatial-data-viewer. In my (spatial) MySQL database, I have a table with 'geometry' elements in it (POINTS). These geometry elements are defined in the Lambert 72 coordinate system (EPSG:31370). My (mapbox) map has the default wgs84 coordinate system.

I succeeded into importing my data from the db into a mapbox-geojson layer (using AJAX with JQuery) with this mysql-to-geojson php script based on geoPHP.

However, the elements still have the coordinates of the lambert72 system, so markers won't be positioned correctly. I know I could use a script to transform these coordinates, but isn't there a 'cleaner' way to get the correct geoJson data (in wgs84 system, instead of lambert72) into my map?

Thanks.

Answer 1

You can use proj4leaflet to reproject your lambert72 coordinates to WGS84.
