My Favorite Tool - QGIS

QGIS (formerly Quantum GIS) is an open source Geographic Information System.

QGIS is capable of advanced analysis and cartography, but I don’t use it for that.

In my research in hydrodynamic modelling, I deal with a lot of spatial data - coastlines, bathymetry, and the like - and this will eventually be processed and plotted using R, MATLAB or Python.

But if I’ve received a file and simply want to take a quick look at it, or if I want to quickly compare two files that use different coordinate systems and see if things line up, most of the time I can throw the file at QGIS and it will show it to me with a few clicks. This approach lacks the reproducibility of a coded solution, but it’s an awful lot quicker for a throwaway visualisation.
