Keith Besserud, AIA, is the director of BlackBox, a research-oriented computational design resource within the Chicago office of Skidmore Owings & Merrill (SOM). With design partner, Ross Wimer, Keith set up the BlackBox studio in 2007 to lead the development and integration of advanced computational concepts within the multi-disciplinary design processes of the office. This includes reviewing computational tools used in architecture and how they apply in urban design.
The Change Matters viewer from Esri can show how your area has changed over a given time period, say for instance, from 1988 to 1990. Las Vegas is known for its phenomenal sprawl over the past four decades. Time-lapseimages from the Landsat earth monitoring satellites reveal in false-color, multispectral imagery how urban sprawl has stretched out from Nevada’s “Sin City” over the past four decades.
This latest video was posted by NASA in honor of the 28th anniversary of Landsat 5’s launch on March 1, but the pictures actually go back to 1972, when the Landsat program began.

U.S. ethnic and racial diversity maps are available from Esri between 2000 and 2010 and show that between those years, diversity increased most dramatically.
According to Esri, a Census Bureau index measures diversity from zero to 100. The diversity score for the U.S. in was 49 in 2000, which means there was a roughly 50 percent probability that two people randomly chosen from the population belonged to different race or ethnic groups. Hispanics, which totaled 35.3 million in 2000, accounted for a significant proportion of this overall diversity.
For those who have made any changes to the default raster type, you will probably want to save your changes. This way you can re-use your custom raster type if you want to load additional raster data with the same properties and functions.
To save your custom raster type, click on the General tab. At the bottom of this tab, you will see a Save As button. Click the Save As button, and save it in the location where you keep all your custom raster types.
Dr. Map from the UC Santa Barbara Geography Department recently came across the extraordinary Metro Wine Map, designed by architectural historian and wine buff, Dr. David Gissen.” This map covers the French wine districts, and the “appellations.”
“The twist is that the map uses the technique pioneered by Harry Beck in the 1930s for the London underground map. Wine districts are colored “lines,” with branches showing the different appellations. One can clearly see, for example the link between Pouilly-Fumé and Vouvray, both from the Loire Valley, but with the former made from the Sauvignon Blanc grape variety and the latter Chenin Blanc.”
