WMS Plugin - NPE maps no longer load since webkit-image changes

[Blackadder]

The NPE layer no longer loads. The parameters for the required http call do not appear to be passed with the URL to dev.osm.nick....

This might also be an opportunity to consider changing the default NPE availability in JOSM from the originally rectified images and the newly rectified versions that RichardF has been using for Potlatch at zoom 14. RichardF is due to make them available at zoom 15 in the next week or so. These zoom 15 tiles are likely to be much more accurate for tracing than the original NPE data.

This may move the issue for a WMS supported feature to a slippy map supported feature?

The reason are warning messages "division by zero" from NPE which are send out together with the NPE maps. Thus JOSM input cannot extract the pictures. We could fix the WMS plugin to cope with such error, but better would be to fix the NPE map server to output only valid data.

Regarding changing to Richard's tiles, I posted this April '08:

I have created another version of my WMS server that uses Richard's mercator tiles and makes them available to JOSM. Because Richard has reprojected the tiles, this provides a better alignment than GBOS without reprojection. Richard is gradually adding map sheets. Wales is available among other areas as discussed on the wiki. ​http://wiki.openstreetmap.org/index.php/New_Popular_Edition

The WMS url is:

The WMS server defaults to EPSG:4326 and also supports Mercator but this is not perceptible on the scale that the NPE is useful.

Once Richard has finished adding maps, we can consider adding this WMS to JOSM as a preset.

Wow it still works! (with the current JOSM) :)

Time to update JOSM defaults?

Added the new server. What to do with the old one?

[anonymous]

Fixing both WMS servers would be an option but retiring the other server might be beneficial because it is worse accuracy and we want to encourage accurate tracing.

I've read somewhere that his name is not Richard, but his name is Robert.

Assuming that the NPE WMS option will be the 4th (ie there are already three listed), then the two lines to add to the bottom of the JOSM preference file are:

wmsplugin.url.3.name=NPE
wmsplugin.url.3.url=​http://dev.openstreetmap.org/~timsc/wms2/map.php?
