Locus Technologies (Locus) providing environmental information management recently announced that it has expanded its web-based Environmental Information Management (EIM) system to work with the Google Maps. Locus embedded Google Maps API to its EIM application to manage analytical data on the Internet. A user can now add overlays of environmental information to the map and display shadowed “info windows,” just like Google Maps. The result is a Google Map Mashup, a web application that seamlessly combines content from more than one source into an integrated experience. With the same ease of finding an address location or driving directions, users can now find subsurface environmental information at their sites, such as chemical concentrations in groundwater. Users can zoom and pan the maps and photos for a seamless view of the geography around sites. Using this Mashup, EIM provides a data box listing the chemical concentration in groundwater, borehole information, and other relevant environmental information associated with location. With Google Maps in EIM, users have the power of a GIS in a lightweight web browser application. The EIM interface to Google Maps significantly improves productivity in managing spatial environmental information by developing and delivering the next generation of internet mapping application services to the environmental industry. The result is the almost instant transformation of previously inaccessible raw environmental data into meaningful, actionable, and productive visual information.
