BBC NEWS | Ancient humans ‘altered’ climate

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.

DepthQ stereo projector from In Focus/RealD/Stereographics

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.


Skype-in, skip the email and leave us a voice mail

We have set up a Skype voice mailbox just as we said we would…5 weeks ago. So, for those of you on Skype, send your comments and questions to my account at jesse-veryspatial and if you aren’t on Skype just pick up your phone and call 304-756-8125. As with any VOIP the sound quality isn’t the best, but it is sound ๐Ÿ™‚ We apologize for the fact that it is a long distance number, but most people have free long distance on cell phones now and this also gives you a reason to go download Skype.

I will not answer Skype calls even if I am online, I let everything go to voice mail. I am not trying to be rude, but I do need to graduate some day :-O

Show note feed or mail list?

Quick survey. Is anyone interested in a dedicated shownote feed (just as the podcast has its own feed) or even a mailing list for the show notes? Both options are fairly simple for me to implement, however I would like to know if anyone would actually use them if I spent to the time setting them up ๐Ÿ™‚ If you would like to see either of these options please email me at

Episode 8 show notes will be out tomorrow (Monday) since I need to write tonight.

Second call for AAG panel participants

I am still looking for bloggers and podcasters who plan to attend the AAG meetings in Chicago in March and who are interested in participating in a panel session on the use of these new technologies. If you are interested please email me at ‘jesse at very spatial dot com’.
