Re: [OpenMap Users] Setting minimum scale for open map (UNCLASSIFIED)

Ben,

Are you trying to restrict the map from "zooming" to a particular scale? Or
are you wanting to restrict a particular layer from rendering/generating at
or past a particular scale?

If the second is true, you can override the layer's "generate" method and
get the scale from the projection and limit there... Something like this...

if (proj.getScale() > minScale) {
  super.generate(proj);
}

The same would suffice for a custom layer as well. Hope this helps.

-Adam
