Online map mashups are about to get a whole lot more sophisticated. A startup in Arlington, Virginia called FortiusOne (based on technology out of George Mason University) is developing a service called Maker! that will let anyone easily find geo-tagged data available on the Web and map it. One piece of the service is already available: a search engine for geo-data called Finder! It lets you find sets of geographical data already on the Web, store it, and organize it, or upload your own. Both are being built around its GeoCommons brand.
