Where I am? Smart Phones
GPS: "fine" location, accurate. Stellites
Wifi: Using a database of hotspots google collected when doing streetview.
3G: Using database of base stations and some very rough triangualtion.
Paths to #amc2012
HANDS ONCollective tracks
Draw your way to the #amc2012
1. As we can not “record” with a GPS that trip, we can draw the path you took to come to the amc2012 with http://www.gpsvisualizer.com/draw/
An alternative solution is to use google earth and
export the route as .kmz or .kml and convert it to gpx
with http://www.gpsvisualizer.com/2. Click save “GPX” in http://www.gpsvisualizer.com/draw/3. Download the .gpx file.4. Upload material to a dropbox folder / email it. Export it as
yourname.gpx5. Use JOSM to merge all the .gpx files into one file.
open google street maps to see all the tracks6. We will generate a unique allthetracks.gpx file with all the tracks
Open the allthetracks.gpx file with google earth. To see it7. Conversion from gpx to svg (vector format) in
http://www.gpsvisualizer.com/8. Open in Inkscape and modify an publish.
