Background from WMS Service

Reported by: katzlbt Owned by: richard@…
Priority: minor Milestone:
Component: potlatch (flash editor) Version: 1.0
Keywords: Cc:


I have high resolution background ortho images and shape data that I can publish via a WMS Service or 256x256 tiles in Google Tiling System coordinates.

(1) I cannot figure out how to use the tiles, because I the background system coordinate system is not documented anywhere (or I cannot find it in (2) Would it be possible that the custom background field could be used to enter a WMS service URL?

Something like this (potlatch could append &width=256&height=256&BBOX=): http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=cat:stanton&styles=&srs=EPSG:4326&

Custom URLs are of the form!,!,!&nmd=20091031 where the exclamation marks refer to z, x and y respectively.

Potlatch does not support WMS, and will not do so in the Potlatch 1 codebase as there is no support for non-spherical Mercator projections.

So you say that my EPSG:4326 rendered ortho tiles are inaccurate when used as background for map making in potlatch? Is the expected inaccuracy >10m for central europe?

Why should you worry about the nonsperical aspect if the WMS Server eliminates that for you? Just use srs=EPSG:3785 (EPSG:900913) and the WMS service will supply sperical mercator image data, isn't it so?

Maybe I misunderstand things.

The coordinate system is Google Tile compatible and not TMS compatible. I will document this on your wiki page.

Please take a quick look at the doc that I have added to the wiki and make corrections if needed:
