[patch] Error message when using the ALKIS WMS layer

[chris66]

When loading the ALKIS WMS layer a warning box appears:

"Die Ebene WMS-ATLAS unterstützt die neue Projektion EPSG:3857 nicht"

After confirming the box, the layer is loaded but the image is not as unsharp (lower resolution) compared to older versions of JOSM.

Old version 8491 is okay.

No error message and image is more sharp.

Old version 8491 is okay.

To get more "sharp" imagery you may go to Imagery / Imagery Preferences / Settings and choose positive tile zoom offset.

@all:
I'd like to add possibility to silence this warnings. I plan to implement following solution:

1. add two additional tags for imagery:

• verified georeference (i.e. the imagery doesn't need imagery adjusting)
• supports non-square imagery requests (i.e. EPSG:3857 to EPSG:4326 works properly)

2. Implement the change, that will not show warning about imagery adjust, when working with verified imageries
3. Add a checkbox in the warning message about imagery adjust, "Do not warn again" instead of current solution, that show the warning only once. This would be saved to user imagery preferences as "verified georeference"
4. Add a similar checkbox in the warning message about EPSG:3857 to EPSG:4326, which would be stored as non-square imagery requests to user preferences

And of course - users will have the possibility to update Maps and do hide the warnings for all users.

Any thoughts?

Enclosed first version of the patch. The only problem that I discovered is some discrepancy between imageries that are proposed by ImageryMenu.refreshImageryMenu() which cover viewed area.

For these - as they are not activated - they do not land in imagery.entries preference - they are always check against the default. So it's not possible to store user decision "Do not show this message again" there. Moving imagery definitions to imagery.entries would change the way, they appear in menu.

Any thoughts how to approach this problem? Create imagery.entries.default?

Checkbox "don't warn again" is okay for me.

I have just checked that if a preset contains
<projections> EPSG:4326 EPSG:3857 </projections>
the 3857->4326 fall-back message is not issued.
It's unclear in the preset doc what that tag is user for.
(If the server is queried for its CECPs and if Arcgis REST supports all projections.)
Unfortunately, JOSM layer installer does not allow setting the equivalent.
And even less pasting the HTTP request template.

Just read the patch: You can't use + and variables to create user visible strings in JOSM, especially not in a tr(). That's an obsolute NO-NO-NO!

Good point, thanks.

preliminary patch

[wiktorn]

Added updated patch version. Now it uses ExtendedDialog.toggleEnable in WMSLayer and similar property naming scheme in AlignImageryPanel

In 9134/josm: commited fix for this bug.
