Founded in 1994, the Center for Land Use Interpretation (CLUI) is a research organization "interested in understanding the nature and extent of human interaction with the earth's surface." To this end, CLUI has adopted a multidisciplinary approach to engaging themselves with its mission and actively produces a number of exhibits on land use themes. The site contains information about visiting the center's headquarters in Los Angeles, and a complete archive of the in-house newsletter, Lay of the Land. Visitors will want to take a look at the ongoing programs and projects, which include tours, information on the residency program for landscape interpreters, and the rather creative extrapolative projects. The definitive highlight of the site is the online CLUI Land Use Database which allows users to search an interactive map of the United States or perform a keyword search to look for sites that are unusual and exemplary throughout the country. Each listing generally contains a brief description, some type of visual documentation, and external website links where available.
