LBNL's RLInt software is not publicly available. This is a change in our policy, relative to what was announced earlier. Not only was the earlier promise financially imprudent on our part, but we believe that it was in technical violation of the terms of LBNL's copyright. We apologize for raising false expectations.
We are in a funding crisis, and our best hope for survival depends on promoting commercial and government awareness of DEMP software and applications. At the present time (5/96) we believe there is no comparable product available elsewhere, nor even under public discussion. The DEMP process is conceptually simple, but surprisingly difficult to implement in affordable computers for problems of moderate size.
In lieu of software we are now offering to process user-supplied map files, in return for permission to publish these maps and use them in our solicitation of new funding.
Our plan - given financial support - is to implement a Web engine which will generate density-equalized maps for users on demand. All the technical components are available at LBNL, including population data and maps at the census tract level for the 1970, 1980, and 1990 U.S. Censuses.
