Why Not? 1) GPS receivers are not accurate enough. 2) GPS receivers are not reliable enough. 3) GPS receivers have a coverage like mobile phones = big holes. 4) GPS receivers do not have the capacity (waypoints) = required laptop. 5) Cost - software - very expensive, or Grass 6) Cost - labour - who is going to pay the person to process the data? > > For personal use, you could 'screen scrape' some whereis > queries : e.g. using whitepages. Scott Howard might light to post the URL's of the rides he has done where he has laid GPS data over this style of map. On the positive side, someone (apologies forgot where I'm filing stuff) from Social Change Online is working on a project for online entry of similar stuff (but it uses very expensive proprietary software). Is anyone interested in this sort of thing? - i.e doing an open source activity? Bicycle Australia (http://www.woa.com.au/ba) has basically decided the way forward for them is currently just to direct people to existing commercial maps and later put some maps, as A5 landscape images, onto WWW pages for people to download and print off themselves. Currently each would need to be digitized and created as a graphic. It would be better however, it there was an online GIS system that people could just create the map they want. -- Terry Collins {:-)}}} Ph(02) 4627 2186 Fax(02) 4628 7861 email: [EMAIL PROTECTED] www: http://www.woa.com.au Wombat Outdoor Adventures <Bicycles, Books, Computers, GIS> "People without trees are like fish without clean water" -- SLUG - Sydney Linux User Group Mailing List - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug
