I have a table of points, actually zip codes and their points.
If a point is an X, Y pair, how do I extract X from a point? (And how
do I create or insert a new point (X, Y)?)
I am given a latitude, longitude pair and I would like to determine
the closest zipcode. I can do this using point_distance, but I wonder
if there is a faster way. If I can extract the separate x, y values
from a point, then I can define my own distance metric and that doesn
not take the square rooot.
So given a point, how do I extract the X, Y values?
Thank you,
Jerry Asher

Dear all,
Are there any utility that can be call by python to create self
extracting zip file. I'm now using the powerarchiever. But the command
line options aren't flexible enough. Basically, I would like to create a
self extracting zip with default file path extraction and force
over-write. The powerArchiever just don't let me call it unless I'm
using the GUI.
Any idea, experience and suggestion are welcome.
Thank you.

Hi, folks.
I am writing a Javascript program that accepts (x, y) data pairs from

first time using text area boxes; in the past, I have used individual
entry fields for each variable. I would now like to use text area
boxes to simplify the data entry (this way, data can be produced by
another program--FORTRAN, "C", etc.--but analyzed online, so long as
it is first...
