Segment and country databases built from World databank I hosted at GRID-Arendal in Norway. The GRID (Global Resource Info Database) nodes are the responsibilty of the United Nations Environment Programme.

World databank I (WD1) was compiled by GRID-Geneva and is a clean, up-to-date version of global boundaries, including new national boundaries with correct topology for countries emerging from the former Soviet Union and parts of Eastern Europe. This new data set is derived from an existing product, the PC World Database (which ESRI derived from World Boundary Database-II or WBDb-II), but includes many recent and significant changes in national boundaries.

City data from World Cities Population Database also hosted at GRID-Arendal.

The World Cities Population Database (WCPD) was produced by the Birkbeck College of the University of London in 1990 at the request of the United Nations Environment Programme in Nairobi.

I have added a number of additional cities, particularly in countries that were a bit sparse before and made the city/country data consistent between the WD1 and WCPD. I made a few small updates to the segment database, namely in Eritrea, Slovakia and the former Yugoslavia. I also added the all of the island, lake and ocean names. I used the online version of the CIA World Fact Book (1998 edition) and the Collins Atlas of the World (1991 edtion) for reference.

I offer a big thank you to all the people who took the time to report problems (and successes) and useful suggestions.

Disclaimer

This is BETA release software; it has been tested to the best of my ability, but may still contain bugs. Please backup your data before trying CITYZEN. Whilst it is highly unlikely that CITYZEN would damage other data in your device (the application operates almost entirely in read-only mode), it is not impossible that this might happen.

If you do manage to get it to crash, or behave oddly, please send in a report. Try to include as much detail as possible: What device and version of the OS are you using? What were do you doing when the problem occurred? Is it repeatable or random? What HackMaster extensions are you running?

Do not believe anything CITYZEN shows you. There might well be errors in the segment or label databases. The sources for both database are nearly 10 years old, and although they have been "updated" a number of times, there is absolutely no guarantee of correctness.

Do not use for any purpose other than as a rough guide to where some things might possibly be.

Please read the note about map accuracy.

Both the World Databank and the CityList databases are in the public domain. Their respective copyright notices are distributed with the CITYZEN package.
