The first lightning talk session at Where 2.0 on location sensing:
- Christopher Schmidt on Geolocation Using GSM Cells. GSM Loc allows you to collaboratively map GSM cell towers using GPS allowing other non-GPS users to approximate position based on signal strength of individual cell towers. OpenStreetMap for cell towers.
-
Jason Kaufman on Gumspots and GSPS. Gumspots is a fantastic crowdpleasing service which maps bubble-gum spots on sidewalks in Manhattan to a geographic location. Gumspots works like semacodes (see image on right).
