teacher points on California zips revisited

[Joseph Norris]

Hello,

Here we go again.  I finally did the following:

Created a shape file of all of my teacher points by their lat/long.  Dropped
the California zip code map on to my laptop and then the new teacher points
file.
I then used fGIS (http://www.digitalgrove.net/fgis.htm)  and loaded the
California zip layer and then my new teacher point layer. I can zoom to the
zip layer but when I zoom to the point layer it is way far away from the zip
layer.  I did this as a sanity check because I did not think that I was even
producing the teacher point layer.  The questions are:

If I create a point shape file based upon lat/lon and I have the California
zip file - why will one not lie over the other - are they not both based
upon lat/long?

Can I open my teacher dbf file, and go search for the zip in the California
zip file and then rebuild the teacher point file with coordinates from the
California zip file thus allowing me to place my points in the zip polygon
that they belong to?

In my California shape file on a dump I get:

     ( 5983045.379, 3224996.563, 0, 0)
     ( 5989542.292, 3224832.974, 0, 0)
     ( 5989921.623, 3224823.475, 0, 0)
     ( 5989953.049, 3224815.898, 0, 0)
     ( 5990112.487, 3224777.458, 0, 0)
     ( 5991452.255, 3224753.633, 0, 0)
     ( 5993483.853, 3224717.643, 0, 0)
     ( 5993800.929, 3224702.331, 0, 0)
     ( 6011910.153, 3224087.577, 0, 0)
     ( 6017051.977, 3223915.448, 0, 0)
     ( 6026300.989, 3223711.249, 0, 0)
     ( 6026888.615, 3222812.493, 0, 0)

What do these values mean - are they lat/long values?

Thanks for all of the help that you have given me so far.
