[OpenLayers-Users] R: Question about OverviewMap with non-standardparameter

[Jacopo Boari]

First of all, thank you for the answer.

I'm using this code:

var options = {
	projection: 'EPSG:23032',
	units: 'm',
	maxExtent: new OpenLayers.Bounds(378450.9407348507, 4986813.622320287, 388641.1529144824, 4995259.018027502)
};
var ov = new OpenLayers.Control.OverviewMap({mapOptions:options});
map.addControl(ov);

But the result is the same as the old code.
Have you any idea?

Cheers,
Jacopo

As with any OL map, the default maxExtent is (-180, -90, 180, 90) - which assumes a Geographic projection.  If you are using a different projection, you need to set the maxExtent to something more appropriate.

See
http://trac.openlayers.org/wiki/Control/OverviewMap#Customprojectionsextents
etc.
