A MuellerMap is a Google Map mashup that incorporates video or slideshows on map points. Unlike traditional map mashups that require hosting data on a server, MuellerMaps run from data stored in a simple Google spreadsheet, making them cloud-based and easy for average users to update. To update a MuellerMap, users simply add or remove rows of information in the associated spreadsheet. MuellerMaps also include a customizable info tab for additional details.
