Notes for HTML version

The main text is that of the original printed document (thanks to Peter Matthews who had a copy of it on disk). I have just added HTML tags & links for use on the web. This is my first try at HTML - and I was in a hurry to get it out so bear with me if it is a bit crude in places! My local (country town) bookshop does not stock any HTML manuals, but I have one on order!

The text of the tables was retyped from scratch and a few spelling mistakes and typos may have crept in - please let me know if you see any so I can fix them.

The symbols in the tables were scanned from the pre-existing printed manual (thanks to Geoff Hammond) - hence the slightly ragged apparence of some. I have redrawn a few where the detail was too small to see easily, or was too muddy. I hope to redraw them all from scratch eventually, but for now this will show you what is intended.

The images were scanned at high resolution and your browser should be scaling them down to fit the table at a reasonable width and height - hence some small symbols will look bigger on your screen than they would be in actual use. The ASF document makes no suggestions (at this stage) concerning the actual size to use - this is left to the draftsman to decide.

Acknowledgments

E. G. Anderson and others, the original authors, did all the REAL work in compiling the standards. The original document was published in the ASF Newsletter 79 (1978). A separate print run was also made at that time. It was reprinted in The Australian Karst Index with additional entrance symbols (Tables 10 and 11) in 1985.

Geoff Hammond (VSA) scanned the images from the original printed tables, cut them into separate GIF files for each symbol and did some initial cleaning up. He also gave advice on html style.

The rest is all my own work and the blame for it is mine (Ken Grimes) - with interference from Carol Layton.

Possible problems with different web browsers.

I have been testing the tables with two web browsers: the OS/2 Web Explorer and Netscape v2.02 for OS/2. Netscape works well, but the Web Explorer had some problems, especially with the images. If you are using other brands of browser - or non-IBM-PC platforms you may also have some problems.

Your browser should be scaling the images down to fit the tables. This causes some unavoidable problems as line thicknesses may get distorted or become "jaggy" and some detail may get lost.   If you have trouble seeing the detail of some of the more complex figures, use the "View this Image" option available from the Right Mouse Button to see a larger view (that is in Netscape - I trust that there is a similar option in other browsers).   If some of the images are too big in the tables, then your browser is probably not scaling them down correctly.   Perhaps you should try to get a new browser that is compatable with Netscape v2 or better.

If your browser is scaling the images correctly the following image should be about the height of two lines of text (40 pixels to be precise).

If, instead, it is larger - about 4-5 lines (90 pixels) high - then your browser is not re-scaling the images.

If, instead of a figure of a arrow with a circle on it, all you see is a funny icon, or an empty box with a cross in it, then your browser may not be downloading the images automatically. Check if there is an option hidden in one of the Option/Configuration/Setup menus that says something like "Autoload Images" or "Load Graphics" and make sure it is switched on.

In theory, you should be able to print the tables from the browser screen, but if that fails you may have to save the .gif images on you local machine and view and print them with a separate program. Note that if you tell the browser to save a copy of the page locally, it may only save the HTML text, and not the associated images! Netscape lets you click the Right Mouse Button on an image to get a menu that tells you the file name (if you wish to download it) and gives you the option to save that image on your machine. If your browser does not do that try using the "View Document Source" option and look for file names ending with .gif and following a string that says <IMG SRC=....

Note the filenames, and you may be able to download the GIF file(s) by taking the URL for the web page (shown somewhere on your browser screen) and substituting /FIGS/filename.gif for the last word of the URL. (The last word - which you replace - will probably be of the form /stab-nn.html where "nn" is a number-letter combination.)
