*Map II 1.5, ThinkSpace Inc., The University of Western Ontario Research Park, London, ON, N6G 4X8 Canada, Free, Raster-based GIS program with some image processing capability. Macintosh version of the Map Analysis Package GIS program. Every map is displayed in its own window with its legend in a separate window. Map objects can be displayed in pure colors, in colored patterns, or in black and white patterns (the latter are required if Map II is used on a monochrome Mac). Commands supported are: Align, Average, Clump, Combine, Compute, Count, Cover, Cross, Drain, Filter, Flip, Grade, Interpolate, Maximize, Merge, Minimize, Mosaic, Orient, Parallel, Profile, Radiate, Recode, Respace, Rotate, Sample, Scan, Score, Slice, Spread, Subscene, Translate, and Warp. Map II 1.5 can import and export data in the following formats: TIFF, SYLK, ASCII/binary and PICT. Binary input routines very flexible; can load LANDSAT images. Will run on 1 megabyte monochrome machines, but really needs color and more than 4 megabytes of RAM to start to run at a decent speed. Versions for Macs with and without FPUs.
MapGrafix, ComGrafix, Inc., 1765 Carnegie Avenue, Clearwater, FL 33756, Ph 727 585-7799, Fax 727 518-1584, 800 448-6277, $995. A powerful GIS system (actually the first that was ever put on a microcomputer) that supports many functions; about the only thing it doesn't seem to support is image processing (it requires a user relational data base). It uses a typical Mac user interface to make available many tools for digitizing and creating map layers. The program offers a bewildering variety of input and output formats; it can, for example, translate between ARC/INFO data base files and its own and will read data in standard USGS formats. Maps can be georeferenced according to a large number of projection models. Mapping options produce contour maps and a variety of base maps. It can take advantage of a network to provide distributed jobs linked to a central data base and calculates in the background under Multifinder. The program outputs graphic data to standard Mac printers and has its own plotter driver. MapLink supports translation to other formats, Map View permits coordinate changes and georeferencing and MapGraf Display is run time viewer that allows full access to data but no modification. Full MapGrafix specs on line in a pdf file. Just imagine having a powerful vector GIS system like ArcInfo but with a native Mac GUI!
MAPublisher 2.0, Avenza Software Marketing, Inc, 3385 Harvester Road, Burlington Ontario, Canada L7N 3N2, 1-800-884-2555, $395 USA, a GIS plugin system for Adobe Illustrator on the Mac and Aldus Freehand in Windows. Educational discounts are available. This new version greatly increases the ease of use and the functionality of this remarkable software that effectively transforms Illustrator 6.0 into a vector GIS program.
The new version includes over 38 filters. It can directly import many common mapping formats, with all of the database attributes intact. Formats currently supported include USGS DLG and SDTS, Arcview Shape, ARC/INFO generate and MapInfo mid/mif files. They are working on a Tiger importer for a future release. Additionally, AutoCAD DXF and geo-referenced TIFF and JPEG files can be imported.
Other features include: automatically saves new imported files onto their own named layer, allows conversion between map projections with customized choices and over 100 projections, converts the scale of the map's current coordinate system to other scales and page offsets using the transformation feature, allows files to be saved in Adobe Acrobat PDF format intact for cross platform exchange and Internet publishing, includes new layer management tools including select by feature type or select same as legend items, supports joining multiple arcs with associated attributes to represent a single map feature, has a new locator tool that shows the real-world coordinates based on each layer's projection in a floating window and supports and draws grids. Single or many features can be labeled with features from the stored attributes.
As in the previous version map features can be selected using a boolean selection dialog box. Version 2.0 makes MaPublisher an absolutely indispensable cartographic tool. It is easy to use, can handle a vast amount of data and makes Illustrator an even more useful tool for map production.
In addition, the MapPublisher 2.0 CD-ROM includes a number of cartographic path patterns, that can be used with the new path pattern stroking capabilities of Illustrator 6.0, and a font with standard U.S. National Parks symbols.
MF Works, ThinkSpace Inc., The University of Western Ontario Research Park, London, ON, N6G 4X8 Canada, (also Rockware) See web pages for pricing, MF Works couples a powerful suite of analytical and modelling capabilities with the user-friendly interface of the Macintosh.

*Paleoclimate, Earth In Motion Technologies, 2476 Bolsover, Suite 491,,Houston,TX,77005,USA,(713) 660-0231, $399, A desktop climate simulator has been developed based on the Parametric Method. The simulator can run under the Apple Macintosh*, UNIX*, VAX*, and MS-DOS operating systems (4 Mb RAM required). The user provides a reconstruction of paleo-shelf edges, coastlines and mountain belts (20 Phanerozoic paleogeographic timeslice interpretation provided), an axial tilt (season), and a pole-to-equator thermal gradient, and the program will simulate pressure, wind direction and speed, upwelling, precipitation, and temperature. The user can also set the grid spacing of the simulation, thereby controlling resolution and calculation speed. Simulations are usually completed within 3 minutes, allowing rapid turn-around time for results. Output is in a format compatible with the PGIS/Mac (above) and can take the form of contours and/or symbols. Output can also be directed to ASCII text files, which can then be read by spreadsheet, database, contouring, or statistical analysis programs to aid in comparison of sensitivity testing or model-to-model comparisons.

*PGIS/MAC,Earth In Motion Technologies, 2476 Bolsover, Suite 491,,Houston,TX,77005,USA,(713) 660-0231,395,,The Paleogeographic Information System/Mac* (PGIS/Mac) is a system for display, maintenance, and analysis of plate tectonic information. It is also capable of integrating user-supplied data into a plate tectonic context. The system runs on a Apple Macintosh* (Mac II or better, 4-8 Mb RAM, with color preferred). The program can produce color plate tectonic reconstructions for any time since the Cambrian, plotted at any scale in one of three map projections (rectilinear, Mercator, Mollweide). The user can easily plot and interact with their own data on these reconstructions. The user interacts with the data on the reconstruction in a way similar to the use of a Geographic Information System (GIS, hence the name). The user can supply points (e.g. well locations, fossil locations, paleomagnetic sample sites), line segments (e.g. faults, contours, lineaments, seismic lines), and/or polygons (e.g. paleogeographies, exposed outcrop boundaries) in present day geographic coordinates (accuracy +/- 9 meters). The correct plate tectonic element is automatically assigned, and the data are moved to positions appropriate for the geologic time selected. If the user supplies data points, the size, color, and symbol type can be set. When the user clicks on the symbol that represents a single point datum, a window pops up with a report of all the attributes of that point. If line segments are provided, their width and color can be controlled. If polygon data is displayed, the color-fill as well as the pattern-fill can be defined. When the user clicks inside of a polygon, a report is displayed detailing the attributes of that polygon. A high resolution plate tectonic model is provided with the system (from the PALEOMAP Project, C. R. Scotese). This model can be easily modified by the user, both in terms of the position of the plates, and the addition of new/different plates. Sample point, line, and polygon data sets are provided to serve as a template for user data. Also provided with the program are a series of 20 Phanerozoic paleogeographic timeslice interpretations (Scotese & Golanka, in press). Output options include standard Macintosh printing functionality (color/gray scale if available), or maps can be saved as PICT files, suitable for use with Canvas*, MacDraw*, etc. The PGIS/Mac is also capable of saving data in a format that is suitable for input into a standard GIS (e.g. ZMAP*, ARC/INFO*). Animations can be made for user-supplied time ranges and intervals, and saved as PICTs for importing in animation specific software (e.g. MacroMind Director*). Data is input as standard text files, but can be stored in database, word processor, and/or spreadsheet programs. Input links to mainframe databases (Oracle*, INGRES*, DB2*) are also being developed.
*Phil 1.0,PetroDynamics,12410 Meadow Lake Dr., Houston, TX, 77077, USA, (713) 293-7727, $395, A monochrome version of Phil 1.5 that includes many of the features of the color version. However, graphics include only geologic cross sections, relative sea level analysis, stratigraphic columns and chronostratigraphy. Models are limited to 600 columns and 200 time steps. This will run on any Macintosh with 2 megabytes of memory.
*Phil 1.5 ver 4,PetroDynamics, 12410 Meadow
Lake Dr., Houston, TX, 77077, USA, (713) 293-7727, $8500, Interactive
program for modeling basin development based on sequence stratigraphy
theory. There is a 30% academic discount. Users can model stratal
patterns in tectonic settings such as passive margins, foreland
basins, growth faulting, and salt diapirs. Effects of changing
sediment volume and type, subsidence, eustacy, erosion, pre-existing
basin floor topography, slopes of depositional interfaces, basin
floor fan timing and geometry can be tested. Tectonic settings can be
modeled by varying the distribution of subsidence/uplift rates with
respect to the source of sediment supply. Subsidence rates can be
treated as linear or cyclic variables. Clastic or carbonate sediment
supplies can be modeled and both traction and suspension sediments
are considered. The effects of headward erosion, channel incision and
surface beveling can be introduced. For those with either lots of
time or a fast Macintosh an elastic algorithm can be used to account
for lithospheric flexure due to sediment loading. Basin edge
formation can be displayed as a color, animated sequence during model
execution. Color graphical representations include geologic cross
section, paleobathymetry, chronostratigraphy, depositional
environments, relative sea level analysis and stratigraphic columns.
Output is either textual or in PICT format. Requires a Mac II with a
minimum of 8 megabytes of memory, also a version for the PowerMac.
Includes PHIL, Batch, Utility and
BasinWorks.
Utility is a tool for manipulating input data and writing the
results of PHIL simulations in spreadsheet form. It allows users to
convert from two-way travel times to depth horizons, and can perform
two-dimnsional backstripping analysis and calculate estimates of
sediment flux history. PHILUtility allows users to build models
larger than the current number of layers (greater then 600 layers is
possible). 680x0 or PPC.
Batch uses stratigraphic inversion technology in the simulation. It accepts observations that include digitized seismic horizons and a paleobathymetric model and converges towards a model that is the closest match between the constraints, providing a final statistical analysis of the differences between model and observation. As the name implies it can remote build stratigraphic models, queueing up to 20 projects and producing binary result files, movies and the resulting figures of these projects. The program will also build interposing models between two end-member models, allowing a pseudo 3D model to be constructed along basin margin strike by changing sediment supply, subsidence rates or location and magnitude of faults.
Philux v 5.2.06,PetroDynamics, 12410 Meadow Lake Dr., Houston, TX, 77077, USA, (713) 293-7727, $39,500, interactive program for modeling hydrocarbon migration. There is a 30% academic discount. The detailed framework provided by the stratigraphic simulation results provides a much improved framework in which to migrate fluids. The Hydrocarbon Migration algorithms in PHLux simulate migration of oil, gas and water as separate phases. Movement is drive by potentiometric gradients that are created by pressure buildup by ground water flow and compaction and tiling of beds. Primary migration is drivign through excess fluids and pressure drive expulsion. Secondary migration due to vicous forces and gravity segregation is support. The model employs a finite difference solution within a Lagrangian grid. There are versions for various UNIX platforms and Windows 3.1, 95 and NT.
