Navit-1

Thanks to Alessandro, stefan_schmidt, cp15 and all Navit developers I have done a small ("not really working") preview of Navit on Neo1973 at Telemobility Forum 2007. Thanks to GFoss guys to invite me. Tyrael

Setting up Navit

I got navit set up and configured to the point where it follows me on the map. It doesn't have street names or any other information, just the map and the cursor showing the location and direction. Here's what I did:

• Install navit ipkg on NEO
  • Build using a local environment: make build-package-navit
  • Download from User:Alessandro repo (http://aiurlano.netsons.org/OpenMoko/ipk/armv4t/)
• Set up your local maps
  • Openstreetmap - follow directions at http://navit.sourceforge.net/wiki/index.php/OpenStreetMaps
  • Here's an example of what I did to get the maps for the area around Seattle, Wa where I live:
    • figured out map coordinates using http://informationfreeway.org/?lat=47.520270037501454&lon=-122.20130713167327&zoom=9&layers=B000F000
    • Downloaded 4 regions from openstreetmaps

wget -O map1.osm http://www.openstreetmap.org/api/0.5/map?bbox=-122.2,47.5,-122,47.7
wget -O map2.osm http://www.openstreetmap.org/api/0.5/map?bbox=-122.4,47.5,-122.2,47.7
wget -O map3.osm http://www.openstreetmap.org/api/0.5/map?bbox=-122.4,47.3,-122.2,47.5
wget -O map4.osm http://www.openstreetmap.org/api/0.5/map?bbox=-122.2,47.3,-122,47.5

• • • Made a navit binary map file using the osm2navit binary that comes with the navit package on my linux box

cat *.osm | bin/osm2navit --dedupe-ways > mymap.bin

• • • Copied the map to the NEO

scp mymap.bin root@neo:/home/root/card/map

• • • Changed the navit.xml file on the NEO to use the new map

vi /usr/share/navit/navit.xml
<map type="binfile" enabled="yes" data="/home/root/card/map/mymap.bin" />

• Run navit
  • Start gllin
  • Start gpsd ( gpsd /tmp/nmeaNP )
  • Start navit
