Mapping tools for Open Systems and GPS's with open specs.

Features:

• GPS tracking in real-time (1-second update rate)
• full street map of the USA
• optional 1-meter per pixel "satellite" imagery.

• uses any standard NMEA (or SiRF, Garmin or Motorola-M12) GPS
• runs under the X11 Window System (X-windows)
• runs under Linux
• uses the featureful Gnome/Gtk toolkit
• user-settable colors for map features
• user-settable display cut-offs for map features
• user-settable display cut-offs for map feature names
• can store millions of waypoints
• altitude and time information in waypoints
• can store millions of tracklog points
• altitude and time information in tracklog points
• can store thousands of routes with thousands of points each
• routing - automatic trip route generation (experimental)
• on-the-fly re-routing for missed turns
• north-up, track-up or destination-up views
• multiple independent map windows
• tracks multiple GPS's (requires an internet connection)
  See where your friends are.
• voice output (via festival)
• maximum zoom is under 10 meters full-screen
• minimum zoom is over 10,000 Km full-screen

Gnomad status report:

2005-6-30: It has been a long and difficult journey to get a full map of the US generated in one go. Now that I have an amd64 with 4Gigs of memory I was able to crank out the full vector database. It comes out to a file just under 8Gigs in size. I'm currently building and running under fedora (FC4 to be exact). That has essentially forced me to upgrade to gnome-2 which is different enough to be a real pain in the neck.

2005-8-13: The first distribution will be a binary-only release for Fedora (FC4) on amd64. The full data set is just too big to map into a 32-bit CPU's address space. By the time I add paging to the code to allow it to run on 32-bit machines, nobody but a few retro-computing fans will care about that feature. It just seems like wasted effort. The size of the data-set also means I can't distribute from here via ftp, so I suppose I'll get to figure out how to distribute via torrent.

2005-8-26: USGS TOPO's, High-Resolution Natural-Color Overhead Imagery and BW Overhead Imagery have been added. New screenshots uploaded. RPM-generating scripts have been written, but the large data-set size found a bug with Redhat's RPM format. The 8-gig vector-map data file will have to be distributed as a tar file.

2005-9-28: Since initially this will be a binary release I'm thinking that the Creative Commons License would be the most appropriate. I certainly want folks to share it, and GPL without the source being distributed makes no sense.
