ESRI recently announched the 2010map mashup challenge and invites developers to present a map mashup and tell the story behind their mashup. One interesting and creative example is the mapshup by Dave Bouwman – Visualizing Executive Compensation. The story behind this mashup:
Executive Compensation packages are so large that they are hard to comprehend. We gathered compensation data from the New York Times, county income data from the IRS, median household income data from ArcGIS Online and mashed it all together in the ESRI Flex API.
The development was done with the ESRI ArcGIS Server Flex API and data from the US census report on ArcGIS Online and a New York Times article about “Pay the Top“. Additional they build an iPhone App about this topic.
According to Daves Blog the idea was born because of the public indignation about the bonuses paid to AIG executives. Most people find this huge amount of money too abstract to think about. The mashup should help people to get a feeling about salaries of top managers in the US.

If you know about another interesting map mashup or idea about an map mashup let me know.

Thanks Joe – to be fair though, I did not build this by myself – the other 6 members of the DTSAgile team were critical to pulling it together so quickly.
Cheers,
Dave
