Am thinking about devising a map-based survey of derelict places, and am looking for ways for respondents to add points of their own to a web-based map.
So I need a survey tool, and a mapping tool. Have looked at Twtpoll as the possible survey tool. Seems friendly enough. But am wondering if I can get Google Docs to do a map-based survey.
On my way through the various sites turned up in a search, I found POI Editor, which makes gmap-based GPS data files via the gmap UI.
