OK, I'll buy that. I'm disappointed to hear that, though, because my .map
file is 3400 lines long and I've got 4 versions of it to alter each time
I make a change because I provide users a java-applet based version of the
page and a non-applet version, as well as large and small map variations...OUCH!
This is going to be very tedious to implement, but I guess that's what I
get paid for! :-) <br>
<br>
About the scaleable symbols...I'm not using them because I don't know what
they are? I've got a symbols.sym file defined (that I took from the maplab
tar archive) and it's got a bunch of symbols defined in it and I scale them
with the "SIZE" keyword in my map file...is there something else I could
do? What exactly is a "scaleable symbol"?<br>
<br>
Thanks very much for your help!<br>

AFAIK, classes don't have a status you can access in the HTML legend like
layers (unfortunately). What I know will work (because I do it all the
time) is creating 4 separate layers each with 1 and only 1 class and moving
your MINSCALE and MAXSCALE settings to the layer object. Give all the layers
the same name (very important). </font></span></div>

This will perform exactly the same since you have no crossover of scale,

On a separate subject, you might be better off using scaleable symbols rather
than your current solution. But, perhaps you have reasons for not using
them.</font></span></div>

Same thing. Now I don't have group header bars seperating my layers,
but all the layers still show up and when I click on a layer that
has scale-specific classes, the symbols for all scales still show
up. By the way, I'm on Mapserver 3.6.1 and here's the page to go
to if you want to see what I'm talking about:<br>
<br>
<a class="moz-txt-link-freetext" href="http://cnrit.tamu.edu/maps/map_init.html">
http://cnrit.tamu.edu/maps/map_init.html</a>
<br>
<br>
Click on the very last button on that page (the one that says "FRAMES
VERSION" on it). When the map shows up, expand the "Regional" folder
on the left-hand side to display those layers. The one that I'm working
on right now is called "Parima Survey Households". Click on that
layer to load it into the map, then you'll see the various symbols
I'm referring to show up in the legend. I represent the Parima households
with red triangle symbols and I have different sized triangles depending
on how far zoomed in you are so that they are small at a high scale
and larger as you zoom in...but I don't want all versions of that
symbol to show up in my legend all the time...just the one that's in
scale.<br>
<br>
Thanks again!<br>

Gladly. Here is my legend code:<br>
<br>
[leg_group_html]<br>
<tr><br>
<td colspan=3 bgcolor=#cccccc><b>[leg_group_name]</b></td><br>
</tr><br>
[/leg_group_html]<br>
<br>
[leg_layer_html]<br>
[/leg_layer_html]<br>
<br>
[leg_class_html]<br>
<tr><br>
<td width=15>&nbsp;</td><br>
<td><br>
<img src="[leg_icon width=15 height=15]" width=15
height=15><br>
</td><br>
<td><br>
[leg_class_name]<br>
</td><br>
</tr><br>
[/leg_class_html]<br>
<br>
<br>
However, it does not work as you say (and as the documentation
on the web page says!). Layers that are "off" do not show up
(that's as expected and what I want), that's fine, but layers
that are out of SCALE DO show up, and that's not as expected and
that's not as the documentation states and that's NOT what I want.
For example, I have a layer called Ethiopia_Rivers...here's what
it looks like:<br>
<br>
LAYER<br>
NAME "Ethiopia_Rivers"<br>
TYPE LINE<br>
STATUS off<br>
GROUP Ethiopia<br>
DATA "ethiopia_rivers"<br>
HEADER 'ethiopia_rivers.shp_header.html'<br>
CLASS<br>
MAXSCALE 8710165<br>
Name 'Ethiopia Rivers'<br>
COLOR 102 204 255<br>
TEMPLATE ethiopia_rivers.shp_query.html<br>
END # CLASS<br>
END # LAYER<br>
<br>
Now, when I'm viewing my map at full extent, my scale factor is
1:<font size="3"><b> 20136789</b></font>, therefore if I click
on the Ethiopia_Rivers layer at that zoom level, nothing shows
up in the map. This is the exact behavior that I would expect...I'm
out of scale for that layer, so it doesn't show up in the map
until I zoom in. The PROBLEM, however, is that the "Ethiopia
Rivers" icon and label pop up in my legend...this is counter-intuitive,
contrary to the documented behavior of Mapserver, and just flat-out
frustrating! If the layer is not showing up in my map (because
it's out of scale), then it should NOT be in my legend either.
Grrrr!!! Pardon me for sounding bitter...I'm not lashing out
at you, I'm very grateful for your help, I'm just frustrated at
Mapserver.<br>
<br>
Thanks!<br>
