ECAI is a collaborative project which combines global mapping, imagery, and texts. ECAI provides scholars and other users with a research resource based on digital technology which presents complex combinations of data from multiple disciplines visually and immediately. Thehudreds of projects listed here make some use of the ECAI technology, and come from a wide range of institutions. Some of the projects (e.g. Valley of the Shadow) have individual listings in the Research Database list. Note: Viewing of 3D maps requires the Google Earth plug-in.
