Zoom to Real Point

[Mike Davis]

I use a pop up window that accepts UTM or MGRS coordinates and then
re-draws the parent map to that location.  What I do is take the
supplied x and y values and use them to create a new mapext value.
So:

xmin = xvalue - 250
xmax= xvalue + 250
ymin= yvalue - 250
ymax= yvalue + 250

(250 is a variable number depending on what scale you want the map to zoom to)

I use these to set the parent windows mapext value using:

window.opener.document.mapserv.mapext.value = xmin + ' ' + ymin + ' '
+ xmax + ' ' + ymax

then is is just a matter of submitting the mapserv form in the parent
window using:

window.opener.document.mapserv.submit();

and your off and running.  So far is seems to work pretty well

Good luck
