I have to create a map based on latitude and longitude. I have a lot latitude and longitude which are coming up from database. On the basis of multiple latitude and longitude we have to create a map.
When user hover on map, we have to show the count for particular latitude and longitude.
Please let me know is this possible in OSM?
So you want to show an OSM based map with markers, and each marker comes with its x and y coordinates from your database?
And when a user hovers over a marker, something is to be displayed?
Have a look at http://openlayers.org and http://leafletjs.org … there are several examples how to display markers.
Or go to http://help.openstreetmap.org and do a search there for “markers” or any similar you need.
Maybe there are also some hints in the OSM wiki … try there.
