Geotrace is a geographical traceroute utility. Geotrace provide graphical view on the map. It has many geographical maps. In order to be able to use a new map with geotrace, you only need to know one thing: the longitude/latitude of the top left and bottom right corners. Most maps you will find will be centered on 0,0 (about 5 degs south of Ghana and 10 degs west of Gabon. for those of you who dont know, its in Africa.). So, lets do it step by step: 1) Find a map. there are plenty on the web. Nasas a good place to find them (it is a mess though). Or grab one of the few maps at a site with maps for XGlobe and XPlanet. The image must be in a format understood by gdk-pixbuf (most images youll find will be jpeg or gif which work). 2) Go to the maps/ directory in geotrace. Put the map in there and open up maps.properties 3) on the second line, youll see MAPS:World50.gif, World100.gif etc... Thats a list of all the maps. Add the name of your recently downloaded map on that line. 4) now, you need to tell geotrace what the coordinates are. Add a line to the file that looks as follows: filename:BOUNDARY=lon1,lat1,lon2,lat2 filename: case sensitive, map has to be in the maps/ folder lon1 and lat1: longitude and latitude of the top left corner lon2 and lat2: longitude and latitude of the bottom right corner As I said earlier, for most maps youll find, youll get -180,90,180,-90 which means that the map is centered on 0,0. However, the two world maps (World100 and World50) in geotrace are centered on 10W,0 You might notice that the three maps of the US have another line associated with them. Thats the alber projection. You probably wont have to deal with that. 4) Run geotrace, select your map from the drop-down and enjoy. Limitations:.
