A lot of articles here at Digital Geography deal with maps and projections. You may have wondered how wrong the different map projections are or let’s say, what they lead us to think how big some areas on earth might be. Well, I can not tell you exactly, but the Mercator Puzzle gives you an idea on the errors that we need to deal with. Plus, it’s fun. Drag the outlines and fit them to countries: The Mercator Puzzle by Google. (To be honest, I expected myself to perform better…)
The “Viewpoints” project explores the aesthetic question whether there is a parameter-based method for generating unconventional maps of the world that do justice to the thematic context in which they appear. For this purpose a project-specific software is developed. So far, map production by means of projection has been governed by certain rules that determine the geographical area depicted at the centre of the map. With conventional world maps, the horizontal centre is usually made up by the equator. The project software enables the generation and design of wholly new and unconventional varieties of world maps in simple and structured…
Maps are still the main technique to show geomorphological surfaces on different spatial scales. Step by step new technologies try to improve this approach. In this german article I wrote about a sandbox, which is monitored by a microsoft kinect camera. After some computation a beamer draws different heightlevels on the sand.
We will go straight to the main part of the problem:how to communicate, where you are. Sometimes it is as easy as “one, two, three” but most likely it is as you are talking in another language compared to your listener. Let us assume you say something like “I am in the mall 500m northwest of the church”. Well there is plenty of information in it. More after the break!
Most of you readers has probably come to a point where you asked yourself “WTF, what is this?”. And doing so by thinking and carrying about projections is very common. The good thing about ArcGIS is, that you don´t need to care about that much due to “on the fly projection”:
