Topographic maps of the United States Geological Survey (USGS) are well known to hikers and others. The USGS has digitized many of these maps and published them on the Web as "Digital Line Graph" (DLG) files in vector form. USGS developed and released a viewer for these files, but it runs only on Microsoft Windows.
With help from Will Evans, we have been developing an interactive viewer in Icon for use under Unix.
The image shows part of San Francisco as drawn by the viewer. The Presidio is at the top, with the Golden Gate Bridge heading north off the page. Golden Gate Park is near the bottom; the dashed line in the lower right is an old streetcar tunnel.
The viewer is approaching completion, and we hope to release it sometime this summer. Besides the viewer program itself, we have new library packages for reading ISO 8211 (DDF) files, for projecting map locations, and for converting among geodetic "datums" (reference systems).
Back issues of the Icon Newsletter are still available.
Complete sets, including this issue, can be purchased for $25. This include shipping in the United States, Canada, and Mexico. Shipping to other countries, which is by air parcel post, is $15.
Ordering information is available at http://www.cs.arizona.edu/icon/orderi.htm. There is a link to a form you can use for ordering at the bottom of that page.
This is your chance to get a fascinating collection that covers Icon from its early beginnings to a mature programming language. If you're interested in this "collector's item", we suggest you act promptly, since we'll be cleaning things out and freeing storage space.
Not messaging in the Rebol sense but messaging in the concurrent/messaging-algorithm sense. The program, Crow, takes a Crow file and translates it to Icon. It also does fun stuff like appending a runtime system to simulate concurrency and stuff like that. So it's a superset of Icon.
Documentation, source code, and examples are available at http://www.clarku.edu/~trutkin/Crow/index.html.
Taybin Rutkin can be contacted at trutkin@black.clarku.edu.
The release will be announced on the Icon Web page and via icon-group.
