Data is useless until it becomes information. There are many ways to convert data into intelligent information and if the data you have is a location based data, OpenHeatMap is a great way to do that. 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.
