Computers & Geosciences is a journal devoted to all aspects of computing in the geosciences.Computers & Geosciences brings to its readers information about databases, data structures, computer graphics, numerical methods, simulation models, statistical and expert system methods, image analysis, spatial analysis and other topics of interest to geoscientists working with computers. The term Geoscience is used in its broadest sense, encompassing geology, geophysics, geochemistry, geomathematics, oceanography, environmental science, hydrology, geography, remote sensing and geographic information systems. Papers describing computer methods are preferred, particularly those dealing with algorithms and computer programs, accompanied by examples of their application. From 1975-1995, programs were always printed in the journal. Now only short programs, subroutines and pseudocode are printed, and source code and test datasets associated with published papers are made available for public distribution on Internet via anonymous FTP from the server "iamg.org".In addition to full-length research contributions, the journal also publishes Short Notes, Book and Software Reviews, and Letters to the Editor. ANON (Another Node On the Net) is a new column dealing with Internet issues and resources of interest to geoscientists. Every year there are one or more Special Issues devoted to particular subjects, assembled by Guest Editors. The publication is intended to serve workers in academia, industry and government. Students, teachers, researchers and practitioners should benefit from ideas in the journal.More information about the International Association of Mathematical Geology can be found on the Internet via http://www.iamg.org View ANON on http://www.uh.edu/~jbutler/anon/anon.html.
