"LL-MAP is a project designed to integrate language information with data from the physical and social sciences by means of a Geographical Information System (GIS). The most important part of the project will be a language subsystem, which will relate geographical information on the area in which a language is or has been spoken to data on resources relevant to the language. Through a link to the Multi-Tree project, information on all proposed genetic relationships of the languages will also be made available and viewable in a geographic context. Ultimately, the system will include ancillary information on topography, political boundaries, demographics, climate, vegetation, and wildlife, thus providing a basis upon which to build hypotheses about language movement across territory. Some cultural information, e.g., on religion, ethnicity, and economics, will also be included. "
