Abstract : Two computer programs, HAGER III and HAGER IV, for Hagerstrand's models replicating the spatial diffusion of innovations, are presented. A sample run accompanies each program, based upon Hagerstrand's original Asby(Sweden) data. An iterative analytic solution (routine Omega) for the Hagerstrand models is incorporated in the computer programs. The programs permit a maximum of flexibility in input formats and output choices. Multiple runs are possible, and different data sets may follow one another. The programs are written in CDC 3400 Fortran, for a 32K machine. (Author)
