1 Map definitions of the form `<bottom left> <top right> <width> <height> <filename>` for each map. Each corner is specified in the form `<latitude> <longitude>` where northern latitudes are positive, southern latitudes are negative, western longitudes are negative, and eastern longitudes are positive. 2 3 Latitudes and longitudes are thus written as `[+|-] <degrees> [ : <minutes> [ : <seconds> ] ]` - in other words, a positive or negative number of degrees optionally followed by a colon and a number of minutes, optionally followed by a colon and a number of seconds. 4 5 Widths and heights are specified as numbers of pixels. Each filename must refer to an attachment which has been attached to this page and which has the given filename. 6 7 europe:: 28 -23 73 37 600 450 europe-600x450.png 8 europe-large:: 28 -23 73 37 900 675 europe-900x675.png 9 10 The bundled maps have been generated using [[http://www.mapnik.org/|Mapnik]] according to the [[http://trac.mapnik.org/wiki/GettingStarted|Mapnik tutorial]], together with boundary data (`world_borders.zip`) from [[http://mappinghacks.com/data/|Mapping Hacks]].
