Cool GIS Programs:
GDAL (Geospatial Data Abstraction Library) - the master framework that reads all the various
GIS file formats and performs manipulations, all subsequent frameworks are dependencies of
GDAL
• GEOS (Geometry Engine Open Source) - a unix framework that does map math
calculation. It’s super powerful and complex.
• NumPY - overrides an out-of-date Python library in OSX (in 10.6 / 10.7)
• ProJ - I have no idea, probably has something to do with these .prj files you need
• SQLite3 - give GDAL serverless SQLite DB capabilities
• UnixImageIO - allows multiple image formats to be interpreted by GDAL
GSL (GNU Scientific Library) - provides C/C++ math libraries essential for open-source
mapping utilities to work
QGIS (Quantum Geographic Information System): a full-fledged GIS program where you can
manipulate raster layers, vectors and everything else you need to do a proper map projection.
Tilemill: a map tile creating program. It basically creates the zoomable sets of tiles you see with
interactive maps online. It will take properly formatted raster and vector files from any GIS
software package (like ArcGIS or QGIS) and place them into layers. From here, you can
rearrange the layers, and even style the vector layers of your map using the Carto CSS/SASS-
