Producing maps with xplanet is a wikipedia tutorial showing how to use xplanet as a piece of GIS kit, to make map images suitable for use on wikipedia and other such websites. By the end of the tutorial, you should be able to quickly and accurately produce maps of any region suitable for publication.
Getting xplanet
[simbanai | simbanai toud]See the project page for downloads
Getting started
[simbanai | simbanai toud]Typical command-line use of xplanet (this all goes on one line)
xplanet.exe -projection orthographic -config script.txt -latitude 52.25 -longitude 21.00 -num_times 1 -geometry 600x600 -output xplanet_image.jpeg -radius 70 -fontsize 16
Result:
Script files
[simbanai | simbanai toud]Some of the map data is typically stored in a script file (a text file on your computer) - the script I used for the above map was simply:
[earth] grid=true grid1=10 grid2=10 shade=100
shade=100 is important, because it says that nighttime regions should be shaded at 100% of daytime illumination. When drawing maps, the nighttime shading isn't normally needed, so set that to 100 to turn it off
Projection |
ancient azimuthal hemisphere lambert mercator mollweide peters orthographic rectangular |
config | data script |
latitude, longitude | where to centre an orthographic projection |
num_times | must be 1 (stop xplanet running continuously) |
geometry | width and height of the desired image |
output | where to save the image |
radius | radius of the earth, as a percentage of image width (make this bigger to zoom in) |
more... | try the docs here and here |
Try it again, setting the latitude to 90, shows the north polar area

[simbanai | simbanai toud]How to plot locations on the map with labels
[simbanai | simbanai toud]City locations are available for download - see xplanet site, and can be plotted on maps (as can anything you can generate a lat/long/name textfile for)
