CityZen is a rather aged bit of software and doesn't run well
on PalmOS devices manufactured in the 21st century.
Recompiling it for modern devices is not a trivial matter as it
does all sorts of horrible non-standard things based on assumptions
about the hardware inside old Palm machines. These assumptions are no
longer true which is why it won't run on modern devices.
I am considering producing an updated version to take advantages of
the increased power of todays handheld computers and/or phones.
Possible features include using a proper spherical projection, drawing
coloured maps and having the ability to add customised overlays of
your own data.
A while ago, I built a prototype system to explore how
much processing power would be required to handle drawing
a true spherical projection akin to a real atlas. Assuming
you have the appropriate Java technology in your web browser,
you can play with it here.
In order to produce something like this for PalmOS systems, I would
of course need a shiny new-fangled handheld machine. If you want to
give one to me, let me know!
CITYZEN is a
combination of a world map and a database of country, city, lake and ocean
names. You can zoom in and out, move around the map and measure distances
using the pen.
World: 20,379 line segments
Places: 3,350 entries
The application, segment and label databases, and the run-time preference
database require 162K of memory.
designed to help answer questions like `where is Easter Island?', `what is the
capital of Nepal?' and `how far is it from New York to York?'. It also has a
quiz facility, and can test you on topics such as `capitals of the world',
`countries of Europe', `cities in Brazil'.
The databases used by CITYZEN are compiled from data provided by GRID-Arendal, part of the United
Nations Environment Programme.
This is BETA release software; it has been tested to the best of my
ability, but may contain bugs. Please backup your data before
trying CITYZEN and
