OpenHeatMap Turns Your Data into a Custom Heat Map
OpenHeatMap is a service designed to make it easy for non-specialists to create maps communicating information. OpenHeatMap is a simple tool that takes your Excel, CSV file or Google Docs spreadsheet with Geo data and creates a heat map out of it. You can then share that map online, a bit like YouTube for geographic visualizations.
Any dataset linked to geographic coordinates (house prices, election results, mortality rates, etc.) can be mapped out on OpenHeatMap. Once you’ve imported your data you can tweak the color sets, heat mapping style, and share the heat map by embedding it in your website or sharing a link to it. The tool functions well with both Flash and HTML5 and lets you share them easily via email, Facebook or Twitter. You can also use the tool to search Twitter and visualize the results on a map
When you have a story you want to tell, Maps are a really compelling way to communicate complex information, and if you have a spreadsheet OpenHeatMap will help you build your own. OpenHeatMap is a free service.
