The Next Generation of Gradient Modeling Systems: FORPLAN and PREPLAN

In designing the FORest Planning LANguage and Simulator (FORPLAN), we were acutely aware not only of the diverse information needs of land managment planning, but especially of the confusion and difficulty that have been created by the recent exponential proliferation of systems, simulators, and data bases. We wanted to include the unique capabilities of such systems as the Glacier Park model, FBIIS, FMIIS, GANDALF, TAROT, and the Thomas and others (1977) vertebrate habitat models; yet we were determined to build a system that would invoke automatically those subroutines appropriate to the scope and resolution of the user’s input data. In this way, if the user could indicate what was available for data and what was wanted in the way of information, FORPLAN would provide the best possible level of simulation and hence the most reliable output. The user would not have to select from dozens of possible programs and simulators; the selection and linkage of modules appropriate to specific data and requests would be provided by FORPLAN.
