Best of the Blogs 13 December 2011

Very Spatial show us a web map that uses night-time imagery. It’s a great way for astronomers to gauge the relative light pollution in their area, but – for most of us – it’s just a pretty way to pick out the size of developed cities. The imagery si from 2003, however, so could do with a good update.
 
Vector One informs us that GLONASS now has 24 operational satellites, making it once again globally available.
 
The Big Map Blog has an amazing map from 1834 that shows – in painstaking and beautiful detail – the relative lengths of some of the world’s largest rivers. It’s a must-see for anyone that has an interest in classical cartography.
 
Google Maps Mania has the skinny on a new – and rather ambitious – project that hopes to map the world as it existed during any year in history. The project started with a web-map of San Francisco that combined an 1853 map with data from the 1852-1853 city directory, which is, in itself, a very interesting project.
 
Dr Craig Roberts from UNSW has a post on his blog about spatial and surveying conference overload, and what he thinks can be done about it.
 
The folks over at GIS Lounge are running a survey about GIS employment. Once the total replies reaches at least 500, they will publish an analysis of the results on GISLounge.com.
 
Vector One also has a post that tell us how asset management applications benefit through geospatial tools. A great post to show anyone upstairs the benefits of increasing the reach of your GISystem.
 
And that’s all for this week. In the mean time, be sure to check us out on Twitter and Facebook, and send any interesting stories my way to schester at intermedia dot com dot au.
