One of our professors who is from the UK showed us this site with maps, photos and other information about the National Trail system. If you are visiting, or even live there, and want to know about hiking all over England or just learn about the different regions, check out this site
This is an interesting note on how we have been altering the climate for quit some time. Carl Sauer was conducting research in the early part of the last century on how prehistoric peoples in the New World have been altering the landscape by clearing large areas. This of course can be linked to altering the climate through deforestation as is mentioned here.
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
Geosoft has added Shuttle Radar Topography Mission (SRTM) data to its public server. Elevation data for basically the whole world is available at 90 meter resolution and the US at 30 meter resolution. I checked out the site, and the data is in the public domain and free to download.
Here is the link to their data server
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.
Hot on the heels of finding out about the GeoGraph project in the UK comes the “Your History Here . com – where’s your place?” project. This uses Google Maps to create links to historic information related to locations. Take a look.
This is more Geology than physical geography, but it is still a great concept for a learning park.
