Continuing last week’s podcast “space theme”, CNN has this story about astronomers using new techniques to discover the most Earth-like planet found yet. From the story, “an international team has detected a cold planet about 5-1/2 times more massive than Earth — still small enough to be considered Earth-like — orbiting a star about 20,000 light-years away in the constellation Sagittarius (The Archer), close to the center of the Milky Way.” Now THAT’S remote sensing!
Ok, bad joke… but still exteremely interesting to those of us fascinated with space!
Adena over at AllPoints Blog posted an entry on Platial, an online friend site which uses Google Maps and tagging to add information about place to a spatial location on the map. She links to an article in the Portland State University Daily Vanguard about Platial’s founder Paul Olsen. He likens Platial’s online collaborative atlas to blogging, “but instead of postings centered on people, Platial is a forum for information on places.”
Want to add your favorite 3D game character to GoogleEarth? Eyebeam R&D’s OpenGLExtractor allows you to capture and re-use 3D geometry data in other 3D graphics applications, basically a “screen grab” for 3D objects. The example on Eyebeam’s OpenLab site shows a couple of mashups with Google Earth where 3D data was captured and imported. If you are interested in 3D development for virtual worlds and 3D mapping, check out OpenGLExtractor.
*Note* OpenGLExtractor runs as a plugin for Eyebeam’s GLIntercept, so you would have to have some familiarity with OpenGL programming to use it, but it is a free download.
A Mexican government funded commission is moving to distribute 70,000 maps to aid people trying to cross into the US. They will feature water cache locations, show transportation routes, and locations of rescue beacons. Although I’m not an expert, this is one of the first instances I’ve heard of a government using mapping to help people leave its own country. CNN has the details

The University of Colorado at Boulder’s Center for Lifelong Learning & Design is working on a cool project called Silence of the Lands. Participants use handheld devices to record and geoerefence ambient sounds which are then added to a GIS to generate a collaborative soundscape. The researchers “look at digital cartography as a form of storytelling capable of pervasively feeding back social debate over long periods of time.” They have completed several thought-provoking papers on a number of research foci, including affective geography and metadesign.

Engadget has a link to a review of a new GPS PDA. These devices are to support those of us who have Trimble GeoXT envy, and a budget…well kind of. Coming in at $600 MSRP, I will stick with my tablet and a PCMCIA GPS card. The review, which is at PocketNow.com, has some great pictures and screenshots from its included wayfinding software.

For all you CAD users out there, Yahoo!News reported on Monday that Adobe is releasing Adobe Acrobat 3D, which will allow 3D files from major CAD applications to be saved as PDFs and retain their 3D characteristics. It’s not cheap at $995, but as the article points out, it will be pretty useful to people who need to share their CAD projects for collaboration and review.
An article in Friday’s online edition of The Epoch Times reports that China will spend 200 million yuan (approximagely $25 million US) to survey the Great Wall using modern remote sensing, GPS, and GIS technology. China’s Information Center for Basic Geography will conduct the survey with the hope of determing the exact length and orientation of the Great Wall. In addition, “Mr. Zhang Ji, vice secretary-general of the Great Wall Association of China, said that when the measurements are completed, a 3-D image of the Wall will be posted on the Internet.”
Over at Geology.com, they’ve got a neat Google Maps mashup that shows the highest point in each of the 50 states. West Virginia’s is Spruce Knob – 4,863 feet. Alaska has the highest high point, Mount McKinley at 20,320 feet, while Florida has the lowest high point, Britton Hill at a mere 345 feet.
For those of you familiar with the social bookmarking site Digg.com, search Digg for “geospatial” (or just click the link) and you will see that someone dugg Adena over at AllPointsBlog.com. I am definitely for this and think the community should try to see if we can get enough diggs to push this story to the front page (temporary home of the popular links).
