UCGIS Draft Body of Knowledge

Posted on 2 CommentsPosted in Education, GIS_Software, Groups

UCGISThe University Consortium for Geographic Information Science has made a draft of its GI S&T Body of Knowledge (that’s Geographic Information Science and Technology, BTW) available for comment. This document is part of their Model Curricula. Comments can be made on the associated discussion forum on the UCGIS site. While the document is lengthy at 115 pages there are many pages of bullets. The file is available as both a MSWord document for editing and PDF.

    I am not sure why I sat on this information for a few days without posting it, but Paul and Renee have released their second great podcast for the land down under. It is great to listen to the cicadas in the background in Darwin while it is below freezing outside here in West Virginia :-). Where It’s At podcast 2 can be downloaded directly from their website http://www.whereitsat.org.au or subscribed to via iTunes or the aggregator of your choice.

    The Gigapxl Project

    Posted on Posted in General, Remote Sensing

    The Gigapxl Project is based on an amazing super-high resolution camera built by Graham Flint, which he has used to take amazing landscape pictures, including a panorama of Pittsburgh, which is not too far from us. One of the Project’s main goals is the Portrait of America, where the team travelled all across the US and parts of Canada. The Image Gallery has some nice examples of Gigapxl photographs.

    Popular Science’s website has a great article about Graham Flint and Gigapxl, and the last page of the article also includes some interesting comments from Michael Jones, co-founder of Keyhole (now Google Earth) and his involvement as a supporter of the project.

    Virtual Hiking and the C5 Landscape Initiative

    Posted on Posted in Human Geography, Navigation, VirtualEnvironments

    As many of you know, GIS analysis is based on the notion that alorithms within the computer can be used to analyze the digital representations of real-world physical features such as topography that are stored in the GIS. An example of an algorithm-based analysis would be a Least Cost Path, which analyzes the elevation values between two points and calculates the path between them that would require the least cost to traverse. The cost can be defined in any number of ways. The C5 Landscape Initiative is a series of projects that explore using GIS to represent different conceptions of the landscape as we move through it. One of their GIS-related projects, which incorporates virtual hiking, is called The Other Path. They trekked the Great Wall of China and mapping it using GPS, then returned to California and used various techniques to map out a path in a virtual California landscape using a virtual hiker, “an algorithm that produces computationally derived paths from data in such a way that allows them to be re-followed through the actual world.” The analysis created a virtual path in California that matched the path of the Great Wall in China. Then, they physically hiked the path to compare the experience. It’s pretty amazing stuff and only one of their projects. They have also created the C5 Landscape Database, which has an open-source API for Digital Elevation Model processing and analysis.
