- QGis python bindings with arcpy
I have very mature development environment in python 2.7.5, centered around ArcPy (ArcGIS python bindings) and iPython (a very useful python shell). I just updated my QGis install (using OSGeo4W64), and I thought I would try to add the QGis python bindings to my existing install - here is how to do it!
- Finding the latest climate change data
I recently had a need for updated climate change maps for a client. The client specifically requested that the maps should contain data from the latest analys by the IPCC. After some searching I found the NOAA ESRL/PSD Climate Change Portal. This website provides averages of all models for the variables that I was interested in: temperature, precipitation and acidity in a format that was easy to bring into ArcGIS.

- Arctic sea ice, august 2012
The extent of the sea ice in the Arctic reached a record low for the month of August this year (2012) - with the ice reaching 4.72 million square kilometers. I thought it would be fun to prepare a map over that using the latest available data.
