[mapserver-users] mapcache: How can I configure an attributionlayer with mapcache?

[Lime, Steve D (MNIT)]

Tiles are basically independent images until the client assembles them. You either need to do something to each tile or something using the client. You never know which tile will be in the lower left corner of the display.

The only other option I can think of is somehow exploiting the meta-tiling process (assuming you're using that). Recall that meta-tiling creates a much larger image (to minimize edge effects) and creates the tiles from that. You could, I think, annotate just the corner of the meta-tile. That would give you sparser attribution, but that may not be what you're looking for nor does that guarantee where the attribution will be located.

Another option would be to not worry about attribution on the tiles (they're not the easiest to use) but have a "download map" link that creates a non-tiled image and annotate that.

Thank you for the OpenLayers tip. But i'm looking for a more client-independent solution. Is there something else i can try?

I have done what Steve mentioned recently, using the "attribution"
option for each OpenLayers layer, and then controlled the location of
the watermark with CSS (.olControlAttribution).  Works well!

I found how to do it through the OpenLayers mailing list
(http://osgeo-org.1560.n6.nabble.com/OpenLayers-Dev-f3888596.html)
