Revealing Ohio's Buried Treasure. Centuries ago, earthen structures of great scientific and cultural significance were built in the Midwest, but farmland and parking lots replaced them in the modern age. A new digital project will create virtual renditions of these earthworks. By Michelle Delio. [Wired News] 4:23:16 AM

Mapping Physical Space & Digital Space Together in Our Personal Virtual Space BuddySpace. Now that the notion of presence is beginning to infuse our electronic communication, an inevitable next question is: presence where? Marc Eisenstadt, chief scientist at the Knowledge Media Institute of the Open University in the UK, wrote to show me a Jabber-based system called BuddySpace that locates presence indicators on maps. In the map shown here, Marc (top row, third photo from right) is present in the office, but idle. Martin Dzbor (bottom row, far right), KMI's "chief presence architect," is present and active. And that little dot on the US map, in New England, is me, present and active. ... [Jon's Radio] Ah, the visual image giving us an anchor! A grounding that wires the digital into our mental image of space and sense of presence! 6:33:32 PM

More on Grid Sensors. Dave Fletcher picks up on my riff about grid sensors or sensor nets and mentions a couple of sites that give real time data for seismic data (both for Utah---Dave's ever loyal). As far as I can see, neither of them make this data available in a way that something other than a human can use it. I'd really like to see more of these sites following correct principals for putting data [Windley's Enterprise Computing Weblog] 4:15:01 AM

Grid Sensors. Last week, I wrote about using the temperature sensors installed in cars in a cooperative way to monitor weather conditions in over a large area. It strikes me as I've thought about it over the week end, that there are sensors everywhere and society would be better off if they were widely available. Let me give some examples.

Open GIS Consortium. I've written about a GIS tool called Earthviewer. Jeff Harrison is giving a talk about a group called the Open GIS Consortium, or OGC. OGC is trying to do something similar, but more general and more extensible. They have markup languages for lots of things including geographic data, sensor data, mobile data collection devices, mapping data, and so on. They did a demo last month where they pulled in data from dozens of different data sources all over the world using web services for emergency response. During the project, they actually flew a plane over the area they were interested in and brought in the data live. Pretty cool. [Windley's Enterprise Computing Weblog] 4:08:51 AM
