I saved this information for later reference.
If I ever get around to writing a program that will automatically extract latitudes and longitudes from my FOG Zip reports, this will be good information. *smile*
Hmm, maybe… I'll make the suggestion to Hank for a FOG feature? (who me? I'm not lazy. *laugh*).
Good Luck & Happy Georgering!
HMG in MAss,
:
: First off you need the latituds and longitudes for your hits. You can get these from the zip codes if you don't want to look up the zip codes of all your hits, then you can't have a tiger map. Then you'll have to look up all the latitudes and longitudes. You can do this for free at Tiger Zipinfo.com
: Then you'll have to make a text file and host it on some server somewhere. The text file should contain all the latitudes and longitudes like
: this:
: -longitude,latitude:colornumber::
: For example
: -72.5775,42.2564:blue4:: # 01075 South Hadley, MA
: Comments begin with # and go to the end of the line.
: colors innclude all named colors, I think. 3-5 are usually good numbers.
: Then once you've made your text file use this URL to get your map.
: http://tiger.census.go/cgi-bin/mapgen/.gif?lat=37&lon=-96.75&wid=48&ht=19&iht=350&iwd=550&murl=LOCATION_OF_YOUR_MAP
: I hope this helps.
: If you need any more help you can look at my text file, and ask questions here.
: Peace,
: Ed
