NLT partnered with the National Trust for Historic Preservation to create the second version of the PreservationAtlas. The National Trust wanted to pinpoint preservation locations in one centralized, easily understood atlas. To that end, NLT designed a robust, customized, and interactive mapping application. Initially designed with ESRI’s ArcWeb Services then Powered by the Google Maps API, the PreservationAtlas included map imagery with navigation tools, map printing functions, geographic legends, administrative data entry, mappable search results, photographs, driving directions, and travel itineraries. It housed a database containing over 2,000 points of interest. The end result was not only functional, but also easy to use and aesthetically appealing and has now been integrated into the National Trust’s enterprise content management system.
