- I also updated ftp.uni-erlangen.de:pub/doc/ISO/english/ISO-3166-summary
- yesterday.

- There are a number of machine readable maps available freely on the
- Internet. From a previous posting in comp.graphics:

- The CIA world data bank is available for anonymous ftp at these sites:
-
- hanauma.stanford.edu pub/World_Map
- spectrum.xerox.com pub/map
- relay.cs.toronto.edu doc/geography/CIA_World_Map
- nic.funet.fi pub/misc/CIA_WorldMap
-
- This is apparently a series if latitude-longitude pairs describing
- coastlines, borders, rivers, lakes, islands and the like. It is HUGE,
- like 100 MB compressed (reckon 200-500 MB uncompressed, I haven't
- tried for lack of disk space). But it does sound good!
- ---
-
- I remember that it was only about 10MB of size, but check it yourself!
- (And please don't ask me to mail it because you can't ftp! ;-)
- Another map is alum.wr.usgs.gov:~ftp/pub/map.
-
- It should not be too difficult to extract the data you need from there.
- But you have to define more precisely what you mean by the distance
- of two countries:
-
- - distance of the capitals
- - min/max/avrg distance of points within the borders
- - ...
-
- Another nice idea for a de-luxe UA: If you receive a message, then in
- a good system you'll also get the X.500 distinguished name. Use this
- name too find the geographic location of the sender and show it to
- the user on a small globe icon on on a map if it is in your region.
- Nice idea, isn't it? ISO has already a standard for geographic coordinate
- data, but they still have to define a X.500 attribute for this. Can we
- expect this in the 1992 version? The Internet schema will perhaps define
- one in the next version.
