Hi Jukka, Yes, that’s standard in the PSMA license, the lawyers don’t really understand the technology. If you know about the technology and how to use it it’s pretty much impossible to comply with the text of the license.
If I remember correctly, there’s a similar bit somewhere that used to say (not sure if it’s still there) that you can’t share certain datasets via a web-service (WMS) that others would be able to use (i.e., in their QGIS, or their own OpenLayers thing). But you could use that data in your own public web-services (OpenLayers-esque) application. Needless to say a few seconds with Fiddler or Firebug etc and anyone can use your web-services in any way they want. What we have in the Britain is central govt (I forget which department) paying central govt (Ordnance Survey) to let local govt (county councils and the like) to “freely” use data that the taxpayer has already paid for the creation of, and do so under a long and complex license agreement that takes a bunch of time and effort to comply with (speaking from experience). There’s a lot to be said for the US model of: “the taxpayer paid for it already so it’s public domain, do what you want with it”.

However, while the OS have their faults with regards to overzealous licensing requirements, generally they don’t seem to care if it actually is every tile. Certainly the site we created we made them aware of (they even used it as a case study!) and we used the method as below and it probably doesn’t cover every tile. Oh yes, be sure to set a max scale so it only appears on OS MasterMap and not all of the other products in your zoom stack. You can see it in action here (zoom to 1:5000 or closer): http://maps.warwickshire.gov.uk/ Cheers, Jonathan From: Kirk, Victor [mailto:victor.k...@cubic.com] Sent: Tuesday, August 11, 2015 4:16 PM To: 'geoserver-users@lists.sourceforge.net' Subject: Re: [Geoserver-users] Watermarking Sorry, I completely forgot to thank you for the reply, it came in just as I was leaving for a few days and I’ve only just got back to looking at this issue. I’ve tried what you suggested but my interpretation of the licensing requires each tile requires a watermark. The images rendered with this method only contain part of the watermark, or sometime none if the tile size is small enough. I did look at using a layout (thinking I could add the layout parameter at the proxy server) but I could not see anyway of dynamically setting the size of the logo so it filled 10% of the tile. Are there other tricks I could use? To summarise the my goal, render a graphic that fills a percentage of the requested tile at a particular zoom level.

Watermarking is fairly easy. The way I did it if memory serves; - Create a shapefile covering the entirety of the UK. - Style the shapefile with the watermark so that only the watermark is visible and somewhat transparent (20%?). - Use the watermark as the “top” layer in a layergroup with any of your OS datasets. It works quite well and gets included in all outputs, WMTS, WMS, cached or otherwise. You can see it in action here when you zoom in to 1:5k or closer.

The watermark is to cover 10% of the rendered image. This data only required when zoomed right in. I couldn’t find a way of doing this in Geoserver so I’ve made a modification to the watermarking to accept a zoom level and a ratio of the tile to resize the watermark logo to. The dataset in question is Ordinance Survey’s Master Map, so I’m sure other people must face similar watermark restrictions. Is there a way of doing the above with Geoserver and if not, is there a better way of implementing my changes as a plugin rather than the core? Lastly, if the answer to both of these is no, would such a change be of enough interest to warrant pursuing incorporation into Geoserver’s code base.
