Aviation maps for QGIS version 2.2+ created using freely available data from FAA.

Everything I can find freely online is in here (METARS, SIGMETS, Controlled and Special Use Airspace, Weather Radar etc)

1. Execute "freshenLocalData.sh" to download the databases, shapes etc from Dropbox and extract locally
2. Open "Aviation map.qgs" with QGIS (http://qgis.org/)
3. Explore all of the layers, there are lots of them. Feel free to submit changes, it's not perfect by any means.
