New on this forum, I was wondering if an Open Weather Map Layer had been developped to lay it on top of an open street map showing my position. I would like to correlate geolocation and weather data if possible.
According to http://www.openweathermap.org that service has an API … so you can use their data in order to display on any basemap, which can be OSM.
Showing your position on an OSM based map is another topic, this can be done for example via openlayers.org or leafletjs.com frameworks and HTML5 geolocation feature. Try some internet searching about that.
