In my project i need to create a map with three layers, basic geographic layer at the bottom, a GSM coverage area layer in top of it, and then a location based services layer on top of it. after creation i have to navigate through the map and get the data of a location, longitude,latitude , GSM signal strength and the services available to that position. any one know a tool that i can use to develop such kind of map? if it is a open source one it is better?
thanx
You could try Quantum GIS, an open-source GIS mapping package. It can load spatial data in various forms (points, lines, polygons, grids) and let you navigate and query them.
http://www.qgis.org, any questions would probably be better on the gis stackexchange site and not stackoverflow, since this isn’t really a programming question any more.
