question about overlays</span></font></p>
<p style="margin-left: 36pt;"><font face="Times New Roman" size="3"><span style="font-size: 12pt;"> </span></font></p>
<p style="margin-left: 36pt;"><font color="black" face="Times New Roman" size="3"><span style="font-size: 12pt; color: black;">I am
currently constructing a map with many thematic layers. For those that
don't know, a thematic layer is a layer which color codes certain polygons
based on a certain field, such as population density or something like
that. I want these thematic layers to be able to be turned on and
off. I have each thematic layer set up as a seperate group in the
mapfile, and i set up each one as a seperate overlay in openlayers.
However, my problem is now i have around 40 overlays on my OpenLayers map.
Is this too many? It is taking a long time to load the map now. So
my question, is having a lot of overlays bad practice? If so, how can i
cut down on overlays, but still be able to have each thematic layer be able to
be shown on demand by the user? Thanks. <br>
