libwlocate

libwlocate is a shared library that can be used for location-based services. It checks for WLAN-networks that are available near to a user and retrieves the current geographic position out of them. Thus no GPS is needed for positioning. This WLAN-based geolocation happens without using any of the commercial services that do the same but track the users position and data. libwlocate instead bases on the free OpenWLANMap project.
