ColorBrewer Intro – Selecting Good Color Schemes for Maps

Posted on

One of our listeners, Jody, emailed us a link to ColorBrewer, an online tool to help people select color schemes for maps. It uses a flash-based map to demonstrate how changing colors affects the look of a map and how that impacts the information being represented. It’s a nice tool to give a user an introduction to choosing colors for maps, so they can immediately see the visual impact of their choices. Cynthia Brewer, the Penn State geographer who designed the ColorBrewer, has also written the book Designing Better Maps: a Guide for GIS users.

World Population Cartogram

Posted on

A cartogram is a map that distorts geographic boundaries based on different values of a variable. So, if smaller areas have higher values, they will be deliberately distorted to look bigger. Here is an example of the world map distorted based on population. It was done by ODT, Inc. which produces alternate views of map, such as world maps with South on the top or the Pacific Ocean in the center.

New version of Yahoo Widgets

Posted on

The new version of Yahoo! Widgets (formerly Konfabulator) now includes quite a few Yahoo! centric tools including a Yahoo! Maps widget. After I heard about the new version on SpatiallyAdjusted I checked to make sure that the WebMap Widget we posted a couple of months ago still works, and all is well.

For those of you who weren’t reading back then, the WebMap Widget allows you to view OGC compliant WebMapServices and search by address. We included a couple of default sites but the real utility of the widget is for you to use your own WMS site (ie raid Mapdex).

BBC NEWS | Virtual tour of Africa’s heritage

Posted on

The BBC has an interesting article on the scanning and modeling of heritage sites in Africa. This is along the same lines as some of the work that Sue and I have worked on here in the US and are starting to work on in Japan (now if we can just talk someone to sending us to Japan on their dime 🙂 ). Much of the work to date has not contextualized the individual structures in their landscape which is what we are trying to push in the presentations we have been involved in with Trevor Harris, our committee chair.

NASA’s Aura Satellite Mission

Posted on

Although Landsat is NASA’s most well-known satellite program, other missions are providing a wealth of information about our Earth. Aura, a satellite which was launched July 15, 2004, collects data that are used for studying the composition, chemistry and dynamics of Earth’s atmosphere, including ozone levels, air quality, and climate. At the recent American Geophysical Union conference, maps based on Aura data were presented showing the levels of Nitrogen Oxide (a precursor to ozone formation) in the eastern US.
