Originally coded as a Sci Foo party favor, follow this link (turnhole.com/rapid) to see my proof-of-concept implementation of a mobile Google Earth KML maker. I've been meaning to add error handling to the code, but have been busy on other things. Since it's too much fun to keep to myself, I thought I'd throw the idea and code into the wild, and see what the world does with it. Enjoy. ~Alan

While coding a spreadsheet-to-KML parser for the online spreadsheet EditGrid, I noticed that they created one themselves. You'll need to register for a free account to access the tool (via My Workspace -> Add-ons -> Grid2Map). The EditGrid developers have also exposed the source code! Two weeks ago, Ogle Earth blogged about users calling individual EditGrid cell values from a Google Earth

Concerning indoors spatial data, Mike Goodchild mentioned CityGML. References to interior models, which the University of Bonn initiative tags "LoD4" (level of detail 4), are not obvious on the main entry page, but are described in their presentation slides (pdf) and articles. Besides the CityGML site itself, Directions Magazine has an overview of the effort.

As usual, the blog train rolls on: this blog posted about an entry on this blog and now you're reading it here. Anyway, the point is that Google Maps for Mobile now supports KML (link).
Changing topics
Concerning Photosynth, one interesting avenue may be the inside of buildings. As I ate lunch today, I thought about some work I did on 3D cave mapping in 1999. It involved me taking images and

All the standard sources have covered Microsoft Photosynth, but I wanted to mention a few additional links. For those who have not heard about it, Photosynth is a Microsoft Live Labs product that takes a collection of photographs, finds similarities, and arranges them in three-dimensional space.
As Stefan Geens at Ogle Earth points out, the technology "certainly looks like a prime candidate for

Rumor:
AGI might adopt NASA World Wind as its visualization engine.

Also, referring to my previous entry about conferences, I'd like
to express my appreciation to the people that fed me, housed me,
and invited me to hang out with "the cool kids" over the last week.
These include:
Declan Butler and Nature (for Sci Foo)
Chris DiBona and Google (for Sci Foo)
Tim O'Reilly and O'

I have not watched this video yet, but am posting it for my own notes. I thought others might be interested in it too.

While mostly I've been hunkered down coding, the brief pauses have been outstanding -- particularly the ESRI User Conference and Nature's Sci Foo.
ESRI User Conference
Other geobloggers have talked about the ESRI User Conference, but I'll add my two cents from a virtual globes perspective. First, I should disclose that I was only at the conference for two days, and did not attend any of the

Sony announced a GPS gadget that triggers from your camera's hot shoe. The device records location and time, to be later synchronized with your photograph. Here's a link to a story at Digital Photography Review. The device will go on sale next month for about $150.00.
Of course, if you have a logging GPS, you can do this already by synchronizing the timestamps on your photos with the time/

A few weeks ago, Matt Nolan hosted a Virtual Globes Conference in Boulder, Colorado. Here is the link to Matt's summary, as well as a synopsis from participant Ron Schott.
Matt Nolan also sent me an email regarding several sessions on virtual globes at the December 11-15, 2006, American Geophysical Union meeting in San Francisco:
The Use of Internet-Based Virtual Globes in the Earth Sciences (

Okay, we haven't completely vanished. The three of us graduate students have been busy studying, reading, and writing. Karl is writing a manifesto on Digital Earth; Josh has been working on a paper related to infrastructure for virtual globes spatial analysis; and, I've been reading about mirror worlds, pondering nested coordinate systems, and making pushpins drive the streets of Santa Barbara
