<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Using CGI Mapserver, I would like to create reference maps
that have their base images dynamically generated. The app would be serving
up maps of fire districts. I know the bounding boxes for each district,
so the user would select from a list and go to a map of that district.
Since there are approximately 40,000 fire districts in the <st1:country-region
w:st="on"><st1:place w:st="on">U.S.</st1:place></st1:country-region>, it won’t
be very practical to generate a .gif base image for each district. What I
really need is a thumbnail of the initial map extent, with an overlay that
shows the current view area. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>It doesn’t look like I can pass the name of the base image
file to a reference map file, so I was wondering if there was another way to do
this. Can I dynamically create an overlay layer with a transparent
polygon? If so, which CGI parameter would I pass the overlay’s vertices
in? Or, do I have to do this all on the client side, drawing the box in a
layer over my thumbnail? Can this be done with dbox.js?<o:p></o:p></span></font></p>
