- or most unmarketable of them all, a GIS (Geographic Information System)
- that interfaces to TI-Base. I think that would be really cute- a mapping
- program on a TI. You'd almost need a CD-ROM drive then...)
-
- Ramble mode:
-
- At least, it would have *one* good use. Except that I only know of
- zero public-domain U.S. highway map data. You could zoom in on your U.S.
- map, drawn on the screen in bright pastel line segments, and click on highway
- segments and have it add up the distances. Neat, huh? (Oh yeah. I'm assuming
- a mouse.)
-
- Afterwards it would let you do calculations on the elevation along the way,
- making little profile pictures, averages, that sort of thing. Do wonders
- for your daily Print-Shop kind of job-- make lots of custom world maps,
- zoom in on the Baltics, or cut out Australia, maybe even finally learn your
- Canadian provinces, heck, you could edit your Balkans as soon as CNN tells
- you where to draw the borders! Or just see how Greenland looks when you cast
- it into a polar projection instead of sturdy ol' Mercator. (which, by the way,
- has been dubbed the politically incorrect map for the 90's. You know, the
- one with the bloated Greenland, and on which Africa is smaller than it
- should be in comparison with Great Britain, and Germany looks like the
- center of the world?)
-
- Just making this program tick on the TI would be a real challenge in
- graphics number-crunching technology. Oh boy oh boy.
-
- Some other applications: Useful computerized Census data for 1980 and 1990
- can be found in the public domain. (So are sewer maps for New York but
- never mind them.) With this data, grouped at the state level, filling
- up just one floppy disk, you could answer those nagging questions, like,
- what states have the largest population DENSITY. Or, say, which state
- has the largest surplus female population, percentagewise, and what other
- factors does that correlate with? (Answer: New York, and I bet they're mostly
- elderly people.) All this would show up graphically, in the form of shading
- or coloring or scattered dot densities. Finally, the TI-Base connection:
- say you had a mailing list, and a map of all the zip codes in Texas. (The
- whole U.S. zip code map is too big to even think about.) You could have
- this program read the TI-Base file and draw little triangles where your
- people were! Isn't that neat? Or you could plot all the TI user groups and
- go around testing potential TI-Fest-West sites to check out how far everybody
- would be flying to get there. People use these things in the wider world
- to keep tabs on customers and sales areas; also, forests, and Arabs. Now
- think-- on your TI! Ooh..
-
- OK, dream over. (Where can I get this C compiler?)
