GIS

Note to self: when thinking about "just quickly doing x, using GIS" think a bit harder. The conversion routines such as gdal and ogr can seem simple and then turn out to be quite hard to deal with. EG gdal_rasterize does not actually create a tif file, you have to do it yourself first, and it has to be for the right area of the earth, the right size (granularity) with the right bands etc etc. What might initially seem easy can often not be and involve you in projections, and datums.
