Quantum GIS (or QGIS, or Quantum Geographic Information System) is a “free,
open source geographic information system.” It provides a way for
non-programmers to create maps using GIS information.
This tutorial will walk you through the basics of using QGIS to create SOS-
formatted maps, by going through the creation of the Earthquakes and Nuclear
Power Plants dataset, the Marine Life dataset, the Global Statistics dataset,
and a few maps that are not currently part of the SOS collection.
An excellent set of general tutorials can be found on
qgistutorials.com. Thank you to Ujaval Gandhi for providing
these to QGIS users free of charge. Additionally, you should read SOS’s
Content Creation Guidelinesbefore creating
your map. There is a lot of information in there that can save you from having
to redo an entire project.
QGIS can be finicky. Please save your project often.
QGIS often has trouble exporting very high resolution images. The SOS team
recommends that users use the lowest resolution images that still look good on
the sphere — in most cases, that means a resolution of 2048×1024 pixels for
simple maps and 4096×2048 pixels for maps with intricate details.
