Evolution of Information…

Although unrelated to GIS specifically, this post (simply entitled Information) that I came across on the evolution of how we hunt for information resonated. I guess I can identify with the author, particularly when he describes ways I used to hunt and gather for information (probably showing my age). Check out this excerpt on library card catalogs:

“So if you were researching something, you’d have to pull out a rack in the card catalog according to the alphabetized subject and flip through the cards. If you got lucky, the title of a book or a brief description would point you in the right direction. Then you had to actually find the book, skim through it, and hope that you’d find some information.

I know what you’re thinking about now: you’ve got to be freaking kidding me.

Obviously we deal with information in a very different way today, although with all the ready access to information (although not always data, especially in Canada), one not only hunts for information, but synthesizes and combines information in ways that are sometimes beyond me, into new forms (mashups for example). To the future!

The Simpsons Do Google Earth

Being Friday, I thought I would post something on the lighter side of things. During the last few days, this YouTube clip from The Simpsons has been posted on a number of different geospatial websites and blogs. The show has a pretty amusing interpretation of Google Earth, which is probably how many people think satellite and aerial imagery works. Enjoy.

Unfortunately, this video is no longer available for viewing. 🙁

US Census 2010=Less Data?

As I scanned the blog of Mapz: A GIS Librarian after posting the Firefox Mapping Extensions post, I saw this post on the upcoming 2010 US Census. As we are starting to see the data rollout from Canada’s 2006 Census, it is interesting to see how the US is approaching their upcoming Census.

Mapz points out that the 2010 US Census will only collect data on 6 subjects, with no long form questions on topics such as income, education, citizenship and housing characteristics. Instead, these will be covered by the American Community Survey (ACS), an annual survey of about 3 million households in the US. While the data from the ACS comes out on an annual basis (which is good), currently it only offers data down to the county and city level (not so good). Mapz concludes that this will impact GIS at his work as a GIS librarian by possibly stifling the use of GIS, just as GIS activity is blossoming, and increasing reliance on unofficial and less accurate estimates.
