This is an article that shows the issues with GPS enabled street maps. The problems that Shanghai drivers face when buying ‘fake’ maps is the same everywhere. I disagree with their use of the word ‘fake’, inaccurate is more realistic.
Since I am into historical geography and Historical GIS, I though I would change it up a little and showcase a nice site that uses ESRI’s ArcIMS to display GIS layers and historic maps of Shanghai, China. This project was done by a group at the University of Lyon in France

If you want to know where to find anything about maps and mapping on the Internet, check out Odden’s Bookmarks. It’s a mapping-related links site maintained by the University of Utrecht Faculty of Geosciences that has a handy search function.

In the September issue of GeoWorld, Daniel Sui has a short article discussing the notion of a humanistic GIScience and how geospatial technologies can play a broader role in defining and representing complexe realities

This is another in the line of UK sites we have pointed out this week. Voices maps recordings of interviews with British residents from England, Scotland, and Northern Ireland. Through these you can get a sense of the linguisitic and cultural differences as you move through the country. Some of the recordings include colorful langauge, but these should be marked.
This gives insight into the linguistic landscape of of the islands along with some cultural flair and aural and oral cartography.
This is, along with the discussion on data vs interface taking place on various blogs today, a nice lead-in to our podcast this weekend on ‘What is geographic information’. With the software that are being used and the data needs of today the maps abstraction, which can be tied to its art, has decreased. GeoPlace.com – Top News Stories
I have been waiting to get my hands on one before I blogged this. Clearly I have one, a demo unit from ShaperTechnology, and it lives up to its hype. This is a 800×600, 1600 Lumens DLP projector that can project active stereo images at 120 MHz. This means that when used in conjunction with a stereo capable graphics card and a pair of stereo glasses & emitter you perceive the view in 3D. Traditionally, this would require a large $60k projector or the use of 2 projectors but the DepthQ is a portable $4k projector.
How is this related to Geography? Both in my research and at work we use a significant amount of 2.5D (surface based) geovisualization. By viewing a scene in stereo it allows for a more immersive experience than the traditional 2D views. Any kind of stereo can give this perception, but active stereo is often considered the best for many situations. The other stereo options are passive stereo, 2 projectors with a polarized filter, and anaglyph stereo, generally the red and blue glasses.
So far we have just been using the standard stereo in ArcScene, but we will test it with a few other apps, but I think it is pretty cool.
Here is a cool UK website that details a project that “aims to collect a geographically representative photograph for every square kilometre of the British Isles” They bill it as a geography project for the people, since the photos are submitted, and apparently already have 30,000 grid squares covered.
Software to graphically morph between two maps. I watched the second demo that is interesting, but it isn’t overly impressive. It has great potential if used with the correct maps.
