      SIMMAP is a simple software for the simulation of categorical
      landscape spatial patterns that runs on a PC-Windows environment and is
      distributed without charge for non-commercial use. This program allows
      obtaining a wide range of patterns with any number of classes in which
      fragmentation and classes abundances can be independent and
      systematically varied. It is also possible to obtain patterns with
      anisotropy and to control the minimum mapped unit of the artificial
      landscapes.

      SIMMAP is the result of implementing the modified random clusters
      (MRC hereafter) simulation method. This method provides more general and
      realist results than other commonly used landscape models, and has been
      described in detail in the following reference:

      Saura, S. and J. Martínez-Millán. 2000. Landscape patterns
      simulation with a modified random clusters method. Landscape Ecology 15
      (7): 661-678.

      SIMMAP 2.0 simulations are very low computational time consuming. In
      a standard PC at 333 MHz, typical computational times are less than one
      second for 200x200 pixels patterns, around 2 seconds for 400x400 images,
      and around 4 seconds for 800x800 pixels landscapes. SIMMAP also computes
      several landscape pattern configuration indices on the MRC patterns,
      such as those related to edges, number, size and shape of the patches,
      and some others. The obtained raster MRC patterns can be saved as image
      files in “bmp” format, which may be imported in other image processing
      or G.I.S. programmes if necessary.

      Those who might be interested in a copy of SIMMAP 2.0 please contact
      the author’s e-mail (santisaura@...). A copy of the software,
      along with a short manual, will be sent afterwards. Author acknowledges
      receiving brief descriptions of the applications for which SIMMAP is
      planned to be used.

      I hope that SIMMAP is of interest for your activities. Kind regards,
