FoxtrotGPS

Notes on FoxtrotGPS, the usual Wildsong page -- I write until I have a basic understanding, then leave you hanging.

Looks like you can register at a central web server, and send updates on your position at a selectable interval (default 5 minutes). You can set a status ("What are you doing")

Peeking at the code, it looks like it's using "curl" to send messsges to a Web server.

The projects list at FoxtrotGps.org suggests that standards would be better and that a couple possibilities are XMPP (Jabber) and YouLoc.net

I am looking at GeoRSS and wondering if it's applicable. GeoRSS supports drawing shapes (not just points) on a map, so for example the extent of a flood could be transmitted as a polygon.

I am also wondering how to fit APRS into the picture. I'd like to have APRS stations appear on my FoxtrotGPS map.

The bits and bobs

FoxtrotGPS builds on a rich foundation of open source components.

What I had to install

Starting with a machine that's been used to compile and build projects, I still had to install some stuff.

I downloaded and built curl and gpsd from source, Ubuntu version is outdated.

sudo apt-get install libgconf2-dev libglade2-dev curl sqlite3 libsqlite3-dev \
  libxml2-dev libexif-dev libcurl3
sudo apt-get install bzr
sudo apt-get install autoconf intltool libtool

bzr branch  http://www.foxtrotgps.org/branches/foxtrotgps-dev/

cd foxtrotgps-dev/
./autogen.sh
./configure
make
sudo make install
foxtrotgps

It runs!
