Map Projections 
For Map lovers, something totally worth reading again from MapLab at Wired. Follow the link and see how people obsess about map projections.
Peru’s Nazca Lines
The Nazca Lines in the desert of southern Peru are a series of large designs etched into the arid ground. These designs, called geoglyphs by historians and archaeologists, depict animals, plants and geometric figures and are believed to have been a part of astronomical or religious rituals. Although the exact origins of the Nazca Lines are unknown, some scholars believe they were created by the Nazca culture between 400 and 650 AD. In 1994, they were designated as a UNESCO World Heritage Site.
The figures can be seen by plane, from atop the surrounding foothills, and through the photos and videos of Instagrammers fortunate enough to have made the trek.
The Wired Magazins’ new Blog “MapLab” is going to run a series of posting abut map projections. While some of us use GIS and other map making tools on a daily basis, probably we had to explain what map projections are and why do we have them, few times in our careers.
Now, MapLab is going to give, in layman’s language, some historical background, and the purposes of what for these projections were meant for, when they were first designed by their creators, and so forth.
The first one is about Mercator. I believe it’s a posting totally worth reading.

say you like Remote Sensing tasks, and you like Landsat data, and you like QGIS…then why not take a look at this page/tutorial. You won’t need $x000.00 of software, nor expensive data plus you don’t have to be an expert because the tutorial is very concise and esy to follow.
I wish I had this many years back when I was trying to do the same for a project.
Remember Data.gov? The President does, and he has issued an executive order that should give the information portal a shot in the arm. Starting this
According to the White House blog, this means new data will be served in CSV, XML, JSON and other machine readable formats, and will even be accessible via API in some situations.
As of May 7th 2013 #MapBox & #OSM have made available the new Mapping Editor for OpenStreetMap.org
This thing look impressive. I think it’ll make huge difference around the world, and I know many people and organizations relying on OSM for Humanitarian Assistance Projects.
