Esri Challenge Winners Tell Visual Stories of Poland Elections, Global Terrorism, and More

Redlands, California—The Esri Data Viz App Challenge asked geodevelopers to build interactive, meaningful mapping applications that showcase the data visualization power of ArcGIS. Participants used smart mapping, a new ArcGIS capability, and other tools for developers. The judges selected the following winners:

First-Place Winner, VizItPL!

VizItPL! answers important questions about Poland’s 2010 presidential election. How did people vote in each county? How does it compare with 2005? What factors (population density, unemployment rate, income, and religion) affect voter behavior?

Second-Place Winner, Global Terrorism Analysis Map

The Global Terrorism Analysis Map enables people to view information about terrorist attacks around the world. A dynamic heat map shows events by year or type as well as regional changes from 1978 to 2013. For each incident, users can see nearby facilities, weapons, and people affected.

Third-Place Winner, Explore your neighborhood through the US Census

The Explore your neighborhood through the US Census app invites people to do just that. Users can enter an address in the search box or click any area to discover population and size for each US county. They can also find data about people including demographics, gender, and age.

“With ArcGIS, I was able to finish this project in less than 1,000 lines of code while still putting everything I needed in my application including comment lines,” said Tim Witt, third-place winner and geodeveloper from Melbourne, Florida. “Smart mapping made it easier to create the feature layer renders on the fly without spending much time coding. To visualize the data, when you click on the map, I used Dojo charting, which is included in ArcGIS API for JavaScript.”
