Can you get the scale value MapServer is using on a map where you think there should be
annotation for this layer but there is not? Easiest way to do that is with a simple browse
template like so:
<!-- MapServer Template -->
<img src="[img]"><br>
Map extent: [mapext]<br>
Scale: [scale]
Note that you'll have to set IMAGEPATH and IMAGEURL in the WEB section of your mapfile. Then
you can call the CGI like so:
http://.../cgi-bin/mapserv?map=yourmap&mapext=extent where things go away&mode=browse
If all goes well you should see the generated image and the computed extent and scale. I'd be
curious to see those numbers on a problematic map for 5.2 and 5.4.
