[OpenLayers-Users] getting map scale in layerswitcher redraw...

[John Cole]

This is a repost, since I really need some help on this one :-)  If anyone
has a suggestion on how to get the current map scale inside the
LayerSwitcher redraw event, I'd really appreciate it.

-------------------

I'm working with Lance Dyas' modified LayerSwitcher and I've run into an
issue.  I need to tell the WMS GetLegendGraphic request the current scale.
I peeked at the scale control and used 'this.map.getScale()' and it isn't
returning the results I was expecting.  I put a string append in both the
layer switcher redraw and the scale control updateScale function to get a
trace of what OL thinks the scale is at each point.  Here are the results:

layer switcher> 442943842.5
layer switcher> 442943842.5
layer switcher> 442943842.5
layer switcher> 442943842.5
layer switcher> 442943842.5
updateScale> 442943842.5
updateScale> 216281.17309570312

The last scale 216K is what I was expecting back.  How can I get this scale
in the layer switcher redraw?

Thanks,

John
