Spatial Sampling in the Ocean: A Modest Proposal
At the Esri Oceans Summit there were several “hallway conversations” about a lack of spatial sampling tools in ArcGIS and how this had led people to use Hawth’s Tools (now Geospatial Modelling Environment) and other approaches in order to perform … Continue reading

Red, Blue and Purple: mapping the 2012 US Presidential Election
E
very time an election occurs, maps become a key component in telling the story, but what type of map best tells the story of the winners and losers? Red/blue choropleths? Areas shaded in an array of purples? Value by alpha maps? Dot density by County? Ultimately, the areas used (e.g. Counties) are arbitrary, exhaust space and dictate the visual pattern we see. We can warp them into cartograms but these sometimes distort geography too much for them to make much sense. The patterns we see are as much a product of the boundaries as the voting patterns of real people in real places. This blog entry explores different ways to map election results and describes a different type of map we made to show the 2012 Presidential election results…it’s a multiscale dasymetric dot density web map (viewable on ArcGIS Online).
Pioneering Real Time GIS with Social Streams
The proliferation of mobile, social and sensor data has given us a new playground for analysis and visualization. It is an area we’ve beenparticularlyexcited about from our earliest experiments with streaming data. Since joining ESRI we’ve had the opportunity to focus on these emerging data sources, and integrate them into the larger concept of Real Time GIS. Baking our ideas into this broader framework gave us the opportunity to fully move past Tweets on a map. Continue reading
Using spatial analytics to study spatio-temporal patterns in sport

ArcGIS for iOS and iOS 6.0 release
On Wednesday September 19th, Apple will release a new version of their mobile operating system (iOS 6.0) ahead of launching new iPhone 5 devices. In certifying the final release seed of iOS 6.0 we have uncovered several problems with the existing ArcGIS application.
If your organization is currently using the ArcGIS application on iPhone, iPad or iPod Touch devices we encourage you to wait until we update to the ArcGIS application before upgrading devices to iOS 6. We are finalizing our changes now and anticipate submitting to Apple’s App Store shortly. Once approved you will receive an update notification on your device and we will send out notification with another blog post.
We apologize for any inconvenience this may cause you.

This Resource Center is getting a facelift and a fresh new look. We’re updating the color and styling of the website, adding tutorials for you to try ArcGIS, improving the gallery and video experiences, and much more.
We’ve been testing the website improvements as part of ArcGIS 10.1 Beta and Prerelease and now, in conjunction with its release, we’re ready to share the website improvements with everyone.
Click here to preview what’s coming. Then, on the evening of 6/12/12, the improvements will be applied to this website: http://resources.arcgis.com. All your bookmarks and page share will continue to work; some pages will just look a little different, and there will be lots of great new content.
