[Richard Suchenwirth] - This is my biggest and most favorite project since a long time: a geographic browser with map display and database browser. Most parts of it are on the Wiki at
   * [tkworld 0.2] - previous version, now at almost 0.5
   * [A little database API]
   * [A little database GUI]
   * [Geographic mapping the Tcl way] for first ideas
   * [Defining Tclworld]
   * [Tclworld gazetteer] - major cities with lat/lon data
   * [strimj - string image routines] for drawing marks (for cities, mountains etc... ovals and polygon scaled "too well")
Be aware that this is still in pre-alpha stage, but already running mighty nicely. Download tclworld 0.5 (ZIP file, 250 k) from http://www.digital-smarties.com/pub/tm05.zip

I can also send you the whole ZIP file, just ask for it by mailto:Richard.Suchenwirth-Bauersachs@siemens.com

I first called this tkWorld, but then found out that this name has been taken by another software years ago, so now it's '''Tclworld'''.

A user has reported that he got Tclworld to run under WinCE on a pocket PC. ([RS]) Another wrote "It works well on MacOS X, both on X-11 tclkit and Aqua Tk". More reports, also of problems, are welcome!

Rich map data are available e.g. from "Digital Chart of the World", http://www.maproom.psu.edu/dcw/ - downloaded text files (country outlines) from there can be loaded into Tclworld with the geo::dmc proc.
