Hi Adrian,
Here's a code snippet that should help you find the resolutions of
your map. You can copy/paste/run it in the firebug's (multi-line)
console.
var resolutions = [];
for (var i = 0; i <= map.numZoomLevels; i++) {
resolutions.push(map.getResolutionForZoom(i));
}
console.log(resolutions.join(','));
I hope this will help you.

Hello everyone,
I'm trying to convert my WMS layer to use tilecache in the backend and I have
stumbled over this problem which I can't solve yet:
Here is my request:
http://terra/cgi-bin/tilecache.cgi?MAP=%2Fvar%2Fwww%2Fhtml%2Fmap%2Frtc_base.map&TRANSPARENT=false&FORMAT=image%2Fpng2&MAP_IMAGETYPE=agg&TRANSITIONEFFECT=resize&LAYERS=rtc_base&MAXEXTENT=left-bottom%3D(20.26%2C43.16)%20right-top%3D(29.7%2C48.46)&MAXRESOLUTION=156543&UNITS=m&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&EXCEPTIONS=application%2Fvnd.ogc.se_inimage&SRS=EPSG%3A900913&BBOX=-180,-90,180,270&WIDTH=256&HEIGHT=256
Here is the response of the server:
An error occurred: can't find resolution index for 1.406250. Available
resolutions are:
[156543.03390000001, 78271.516950000005, 39135.758475000002,

I've read over the internet and it seems I need to set the same 'resolutions'
array in OpenLayers and in TileCache. No problem.
My question is: what is my "current" OpenLayers resolution? How can I find it?
Currently, my map has no special options set (about resolutions or zoom levels).
I've looked around the DOM, but the properties there only reflect what I set up
at the map/layer creation.
Thanks.
Adrian
