Changing Seasons

While checking the weather, I stumbled upon this great example of satellite imagery. It’s a simple animated gif, which shows the changing seasons from a polar perspective. Definitely worth viewing! Check it out here!

GIS and Crime Mapping

I recently read a article called Predicting Crime by Ruth Davenport, which discusses the use of mapping crime data to aid the Royal Canadian Mounted Police (RCMP) in Halifax, Nova Scotia. According to the article, the use of spatial crime analysis has resulted in a noticeable decrease in crime because of the ability for GIS to help guide police forces to where they should likely be, based on previously collected data. It’s a great example of how GIS can aid any sector of society, and if you’re interested in reading it, I’ve included the article link below.


Indiana Jones in Space

While reading the February, 2013 issue of National Geographic, I came across a short article on Dr. Sarah Parcak who uses Remote Sensing for finding potential Archaeology sites in Egypt. Using infrared satellite imagery, ancient structures were able to be spotted, even when buried below the surface. This appears to be caused by the material composition of the hidden buildings which stand out from their surroundings. This is a topic which I’ve always been interested in, and I hope encourages others to merge geomatics technology with historical research. Hopefully this technology will bring about countless discoveries in the future, and I look forward to hearing about Dr. Parcak research in the future.

For those of you who are interested, I found a preview of her book, Satellite Remote Sensing for Archaeology, which you can read the first 30 pages/buy at,
