Description of Dept. of Geosciences Contribution No. 72, April 2000
"Dynamic Digital Maps - A Macintosh CD-ROM"
Contribution No. 72 includes a 46 page pamphlet and a CD.
Link to the UMass Geosciences Contributions Series page, where you can order the CD & Pamphlet that make up Contribution No. 72 for $10.
Go here to see a brief description of a Cross-Platform, WEB enabled version of a DDM, including screen-grabs showing parts of the new DDM-NE. This project involves converting the SuperCard DDMs to the Revolution/MetaCard environment, and was
funded by NSF-DUE-CCLI-0127331 (2002-2005). Links fom this page are available to download the new versions of the below described SuperCard DDMs.
The pamphlet is divided into three chapters, the first of which describes the content of the CD-ROM. The second chapter "DDM-Tutorial" contains the text of an introduction to using SuperCard to make Dynamic Digital Maps. The third chapter is a "Dynamic Digital Map Template Cookbook". This "cookbook" provides step-by-step procedures for making a Dynamic Digital Map. The process is done by modifying the SuperCard project "Dynamic Digital Map Template" (DDM.Template) included on the CD, and requires a basic familiarity with SuperEdit and SuperCard, and with the use of a CAD program, and a photo editing program such as Adobe Illustrator and Photoshop and a word-processing program such as MS Word. Click here Pamphlet.pdf for a pdf file of Contribution No. 72, which includes the Cookbook, without any CD.
The CD contains four complete stand-alone programs, three of which are Dynamic Digital Maps, and a Teaching Examples Folder, containing exercises to be used with the DDMs (one of which is a freshman physical geology level lab), and in the case of the igneous petrology exercises the supporting analytical data files for two DDMs that focus on volcanic complexes.
Hardware and Software Requirements
The use of this CD requires a Macintosh computer with a CD, running Mac OS 7.5 (or above), and in the case of the stand-alone programs, from 10 to 20 MB of free RAM. All "stand-alone" (see below) programs can be run with no additional software.
- DDM.NE contains maps, 285 images, 30 QuickTime movies and text for six geologic field trips in western Massachusetts, and shaded topographic maps and the state geologic map for the entire state of Massachusetts. A topographic map for the Town of Leverett, where three of the field trips are located, includes the linework for the bedrock geology of the western area. The program includes a "tour" button for a completely automated guided tour of how to use the program. Just click it and let her run! It's my way of helping one get over the "I don't want to learn another piece of new software blues". See the below "Teaching Examples" heading for ideas on how to use (and we in the department use) this program in physical geology laboratory exercises.
- DDM.SVF is a geologic map of the Springerville volcanic field in east-central Arizona. The program is an updated version of that published on CD by the Geological Society of America in 1995. It includes 74 pictures of the field, and lots of geochemical and geophysical data. It also includes a "tour" button for a guided tour of how to use the program. See the below "Teaching Examples" heading for ideas on how to I use this program in my junior level igneous petrology laboratory exercises. Included is a geochemical data set for use with Mike Carr's IgPet program (see the description in the SVFGeochem Folder below). Although the SuperCard programming is the most primitive, in terms of content, this is the most complete of the DDMs on this CD.
- DDM.TSP is a geologic map of the Tatara-San Pedro Volcanic Complex, located in south-central Chile. It contains a geologic map, modified from that published by Singer and others (1996) in the Geological Society of America Bulletin, along with 191 images and about 600 major and trace-element chemical analyses, 200 paleomagnetic site analyses, and 50 K-Ar and Ar age dates, most with their sites plotted on the images. This program represents the most recent application of the DDM.Template (see below) also found on this CD. As such, it should be used as a model by those interested in building their own SuperCard DDM.
- Below Sea Level is a senior thesis done by Paul Wernau a few years ago, which I have kept updated with changes demanded by the evolution of the Mac OS. It is designed to be an interesting, fun and educational introduction to the geology of the ocean floor.
The DDM.TemplateFolder contains a manual on how to use the contents of this folder to make a Dynamic Digital Map. It also contains the DDM.Template, and file structure (folders) needed for its use, with dummy data for illustrative purposes, and several ancillary SuperCard programs to be used in this effort. It is essentially an outgrowth of a semester-long course I taught during the Fall of 1999 at UMass on "Desktop Publishing of Geologic Maps".
SVFGeochem Folder, and another, the TSPGeochem Folder,contain suites of petrologic data from the Springerville volcanic field and the Tatara-San Pedro Volcanic complex that is formatted for IgPet.
The TeachingExamples Folder includes several exercises (see below) using DDM.NE, DDM.SVF and Mike Carr's IgPet (Petrologic Modeling) program, for use in a junior level Igneous Petrology course.
- "DDM.NE.DeerFldBasinVRGeo101lab" is an example exercise in using DDM.NE as a virtual field trip to the Deerfield Basin.
- "IntroToDDM.SVF_Petro-2000.02.16" is a step-by-step cookbook on how a geologist might use the DDM.SVF as a tool to begin modeling the petrogenesis of magmas of the volcanic field.
- "PetModelLab1-2000.xx.xx" and "PetModelLab2-2000.xx.xx" describe in a cookbook way how to use Mike Carr's IgPet and mixing programs in exercises designed to help students appreciate mass-balance and how that works with the fractional crystallization process in magma petrogenesis.
