Geological Image Digitizing	Advanced Logging Technologies	Box
12009		Beaumont	TX	77726	USA	409
833-2130			Advanced Logging Technologies (ALT) scanning
services specialize in the digitization of libraries of photographic
prints, negatives, and slides at very low cost. Compare the cost of
digitizing an 8X10 core photograph ($3) to the original cost of acquiring
a high quality core photograph ($10-$25) and its original color and
fidelity is preserved forever. A reasonable investment, when you consider
the original cost of acquiring the image. Air is to photographic negatives
and prints what smoke is to lungs, very damaging. Once an image is
captured, its negative and print immediately begin deteriorating. Slowly,
the original photograph will definitely degrade. We only have to browse
through the family picture album to confirm this reality. Photographs
should be digitized as soon as possible to preserve their original color
and fidelity. Once a photograph is digitized, it immediately increases in
value and becomes much more useful to your staff. A digital image can be
instantly viewed, duplicated, analyzed, used in reports, and transferred
to and from any desktop on your computer network. For many organizations
that means world wide access; which is a far cry from a single photograph
in a library of prints available at a storage site that only a few have
access to. Processing photographic media is handled in a fully turnkey
manner, from scanning to final image processing. Scanning is only the
beginning of the process. All images are scanned in 32 bit color, have the
white balance reset, digitally enhanced, and are saved in a customer
selected file format. A minimum of two files are usually generated, one a
high resolution JPEG or PhotoCD archive file and the other a lower
resolution file to use in reports and catalogs. JPEG and PhotoCD are the
principal formats used by ALT for high resolution image archiving because
of their high compression rates and cross platform accessibility.

deep induction LL3, LL7 or long normal. LithoPlots produces lithology,
Hingle, Pickett, Source Rock, and three mineral plots. When using a Hingle
plot the user may lick on the 100% Sw line and drag the end around until
satisfied and new Rwa and Sw values will be calculated. PreEval computes
Rwa, Rmfa, Vclay, PHIT, and PHIE to be used for input into the Eval
application that computes the final porosity and water saturation. A
variety of porosity models (RHOB-HPHIls crossplot, Sonic [Wyllie or AFF
models] or HPHI ls.) are available and the results can be viewed in
various crossplots. Eval is used to determine water saturation in the
flushed (Sxo) and virgin (Sw) zones, moveable hydrocarbons, Vclay,
porosity, and Net pay. If RHOB, NPHI ls. and PEF are present the content
of up to 3 minerals may be computer and graphically displayed. It includes
gas corrections. If the Sonic and another porosity measurement are
available it will computer secondary porosity. Various water saturation
models are available. It is possible to identify coal on the graphic log.
There are versions for Macs with and without floating point coprocessors.

are interactively selected in a minimap and may be selected individually
or by projection onto an arbitrary line of section. 3-D views are made
with isometric projection and any view angle may be chosen. Each formation
name or rock-type is keyed in with a specific pattern that is plotted
within the interval.  50 different editable patterns are available. 
Graphics within the program include strip logs, correlated cross sections,
and fence diagrams. System 7.x is required.

Map II 1.5	ThinkSpace Inc.	316 Cheapside
Street		London	Ontario	N6A
2A6	CAN		345		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. Formerly marketed by John Wiley & Sons;
ThinkSpace is improving over original version. $15 S&H. Includes Hyperview
Kit.

MapGrafix	ComGrafic, Inc.	620 E.
Street		Clearwater	FL	34616	USA	813-443-6807	8500		A
powerful GIS system 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 ($495) supports
translation to other formats, Map View ($495) permits coordinate changes
and georeferencing and MapGraf Dispklay($850) is run time viewer that
allows full access to data but no modification.

MCadContour 4.0	ASC - Aupperle Services and Contracting	#406
720 14 S.W.		Calgary	Alberta	T2R
ON1	CAN	(403) 228-0982	800		Version 4.0 of
its impressive and easy-to-use MCadContour application. MCadContour is
compatible with all macs from the Mac Plus up and can be installed with or
without floating point support - it currently runs on PowerMacs in
emulation mode but a native PowerMac version should be available by the
time you read this. Under the MultiFinder and System 7.x most functions,
including data importing, can occur in the background. Under System 7.x
MCadContour supports Publish & Subscribe, a limited suite of Apple events,
Baloon Help, Virtual Memory and Drag and Drop launching. Well or cultural
data can be imported in text format (though a very intelligent import
routine), digitized directly though the built-in ADB digitizing tablet
interface or read in MiniCad+ format. Data can be imported in a wide
variet

Prdinate systems, including longitude/latitude and single- or multiple
zone UTM. Each individual imported well may include multiple datums (i.e.
formation tops) as well as other textural or numeric information and can
be displayed as a standard AGI well symbol on maps. Digitized photographs
and other PICT files may also imported in a special graphics layer to
display along with main map windows. This highly interactive contouring
program supports both conventional gridding and triangulation surface
modeling, contouring smoothing and labelling, on-screen editing of contour
polygons (including vertex editing and cutting and joining contours) and
and unique dynamic object tags that allow objects or groups of objects to
be removed from the display with a single click. Volumetrics may be
calculated between grid surfaces or within user-defined zones on a grid
surface. A variety of fiducial grids can be displayed, regardless of the
input coordinates. Changing scale is as simple as choosing a scale from a
menu and allowing automatic redraw of the window. Extensive data filtering
and selection tools are available within the mapping environment. Contours
can be ÔbrokenŐ along user-drafted lines (i.e. faults) and offset along
the fault a user specified distance. This requires the user to have some
idea of the amount of lateral offset of contours from one surface to
another, which is a bit challenging, but can be quite useful. This
breaking feature also allows one to draft an area within the map from
which contour lines can be clipped away; good for title boxes or for areas
you just a soon not have people see. In addition to 2-D contour maps
MCadContour now supports interactive 3-D surfaces and 2-D cross sections
that are linked to the main map and tagged object display windows. In the
3-D window single or multiple stacked surfaces can be shown and ÔholesŐ
can be carved into the surfaces to allow visualization of lower layers.
Individual surfaces can be displayed or removed and can be graphically
edited for surface color, shading, etc. Surface orientation and shading
are controlled by a pair of intuitive graphical controls. 2-D cross
sections are generated by drawing straight lines of section or by clicking
on wells in the main map window and having the program interpolate and
connect tops. Initial cross sections are usually incomplete and require
additional editing, but since all unit boundaries are editable polygons,
additional pattern filling and editing can be easily accomplished using
available graphical and textural tools. Up to 10 cross sections may be
defined and active for any one map.Data is limited by RAM, a one megabyte
Mac can contour approximately 10,000 data points and a five megabyte Mac
can handle 60,000 to 75,000 data points.

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.  Recent comparisons with the Low-Resolution Global
Circulation Model indicate that these models produce similar
reconstructions of the gross aspects of climate. Developer's license with
source code is $4000.

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.

330	Houston	TX	77079-1716	USA	(713)
293-7727	8500		Interactive program for modeling basin
development based on sequence stratigraphy theory. 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.

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.

Restore	Bureau of Economic Geology	The University of Texas at
Austin	University Station, Box
X	Austin	TX	78713-7508	USA	512
471-7721	249.95		A full color program to reconstruct
extensional salt and shale terrains. Restore sequentially and
interactively balances cross sections involving extension and salt or
overpressured shale. Unlike many cross-section balancing programs, it can
deal with extensional sections with complex interaction of simultaneous
sedimentation, deformation, and movement of ductile salt or shale. Restore
balances the section at each stage of backstripping. Users can specify
angles for rigid rotation and simple shear of individual fault blocks,
choose from a range of decompaction parameters, track changes in salt or
shale area and extension, separate blocks to show salt reaching the
surface, and graphically remove basement subsidence and tilting. It has a
built in digitizer (ADB) interface for tracing in existing sections. You
select blocks by clicking on them and specifying such parameters as
horizontal shift or degree of regional dip to which they can be unfolded.
Restore is $249.95 (educational and not-for-profit pricing is available).
