Make a Pirate Treasure Map using Microsoft Bing
Explores some of the fun ways to use and interact with maps, mapping data, and geographic information systems. This example uses Microsoft Research map apps (tech preview) as an example. For GIS'ers, this video demonstrates the flexibility and design elements that are emerging in easy-to-use web mapping applications, and that are easily used and understood by anyone. Applications like these are a great way to introduce students to some of the concepts behind GIS, design and cartography.

GIS Spatial Statistics Tutorial using John Snow's Cholera Data: Using the Collect Events Tool
Describes how to use the collect events tool in the Spatial Statistics Toolbox. The Collect Events tool lets you create a feature class that calculates overlapping points and represents them with editable graduated symbols. This tool is useful when working with geocoded point datasets.

Animation of tweets during Superstorm Sandy in New York City using ArcGIS 10 and Tracking Analyst
Using data collected by DensityDesign of Politecnico di Milano, this is an animation of tweets making reference either through a hashtag or free text to Superstorm Sandy. The data was imported into ArcGIS 10 as time-stamped XY data and animated using the ArcGIS Tracking Analyst extension. Each tweet is displayed over a two-hour window - initially as a large circle, fading to a smaller one as time progressed. The histogram at the bottom of the screen shows the volume of tweets over time.
