COGS Then and Now

by Dave Rich

When COGS was started in 1983 the technology for transferring information was very different from today. Our primary vehicle for informing the membership was a printed newsletter which was created with means which are very primitive by today's standards. Figure 1 shows an example of one of these early newsletters.

The masthead was created with a combination of pen and ink drafting and Kroy lettering. The masthead and borders were photocopied for each month. Then the text was created with a word processor, and the text and figures were printed on a dot matrix printer, reduced with a photocopy machine if necessary, and pasted onto the sheet. That sheet was then photocopied, folded and mailed. You could read it on the bus, but once you had read it, there was no more information to be had.

COGS is now moving toward electronic distribution of information. Tom Bresnahan has created a World Wide Web home page on Internet for COGS. It can be found at . The next figure shows the current version.

It was created using HTML (HyperText Markup Language) and lives on the Colorado Supernet server. Users can click on highlighted keywords and automatically be taken to that particular resource. You need to have a computer and be connected to Internet to use this, but you can access a nearly unlimited amount of information by clicking your way through menu choices.

Many organizations are using World Wide Web to organize resources on Internet. COGS welcomes our members and others to use this web page, or, even better, contribute to expanding it and making it more useful. Now you just need a way to take in on the bus.

COGS Adds a Page to the World Wide Web

You can now access COGS on the World Wide Web using a graphical Web browser like Netscape or Mosaic, or using the web browser in the Prodigy on-line service.

The COGS web page address or Universal Resource Locator (URL) is:

When you type this address into your browser, it will display the COGS "home page" located on Colorado SuperNet's server in Boulder. Information on a web page consists of graphics, usually in the GIF file format, regular text, and hyperlinked text, usually underlined and displayed in a different color. Clicking on the hypertext link displays a new page consisting of a different part of the current document, a new document on the same server, or a new document on a different server, not necessarily on the same continent.

The World Wide Web is a network of information linked together with a common addressing system and a hypertext method of moving from one topic to another, and from one address to another. It was created by a group of physicists at Background and Purpose of COGS link causes the browser to jump to the place in the current document containing that information. Clicking on the FTP File Server link in the Background and Purpose section displays a list of files available on the COGS ftp site. All you have to do to download the file is to click on the filename.

Clicking on the December 1994 / January 1995 Issue link directs the browser to contact the Colorado SuperNet Web server and download the text and graphics associated with that issue of the COGS newsletter. The table of contents lists topics on different pages of the paper version of the COGSletter, but the Web version of the newsletter contains hypertext links to e-mail addresses, other articles in the newsletter, and other sites on the Web, including the sci.geo.geology newsgroup, the COGS ftp file site, and links to other home pages, such as the Interpex page accessible from their advertisement.

The future of the COGS pages on the Web is limited only by people, time, and money. What would you like to see from COGS in this department? Please contact me at with your ideas, suggestions and comments.

Environmental Data Models Sought

By Dave Rich

I am currently involved in a project to document data models in use in the environmental industry. We are interested in thoughts, examples, etc. from people managing data for environmental projects. While our primary focus is on technical data for site characterization and remediation, comments on related areas such as document management and regulatory issues are also welcomed. If you have something to contribute, please sent email to the above address, or snail mail to:

Thank you for your help.
