The JOSM slippy map plugin does not have a control for moving the layer 
like the WMS plugin has. I guess one could be added - the slippy map 
plugin could certainly benefit from some serious work (at the moment, 
you can only have one slippy map layer, you can't switch between 
different ones, plus a number of minor other shortcomings).


I've been thinking that we could give JOSM a generic menu (External, 
Background or something) which can be used to add external layers to 
the display. The WMS plugin would then not create its own top-level menu 
but would create its entries there, and the slippy map plugin could also 
populate that menu with its choices. For the end-user, there's no 
difference in WMS and slippy map anyway, it only confuses them.


However I'm not able to work on this at the moment.

Bye
Frederik

in case of a constant offset at given locations (and not some warping

that a user wouldn't have to adjust it manually everytime.

Other plugins (like PicLayer, ImportImagePlugin) also need this feature.
I think this is part of the features that should available for ALL layers, 
independently of their type and of the plugin developers :
- fine tune position, scale and angle (requires appropriate warning and/or 
limitations of course)
- transparency
- renaming

E.g. they should be handled by default by the core, not by the plugins. For 
specific cases only, the plugin should be able to redefine or prohibit them.

Presumably MS would want to just fix this, so perhaps we can simply
report bugs.

It doesn't have to be constant offset, there could just be a
user-editable repository of control points for different imagery
providers in case they're not calibrated so well.  Shifting individual
tiles according to the nearest GCPs would be good enough I think, even
without deforming individual tiles (which would be better of course).

[josm-dev] sac_scale in JOSM - RFC for change of translation

2010-11-24 Thread Fichtennadel
Dear readers of OSM tagging and josm-dev lists,

after some discussion on german and italian mailing lists it has been
proposed to change the display values of sac_scale in JOSM's path template
to T1 ... T6 (see http://wiki.openstreetmap.org/wiki/Key:sac_scale for
description,
http://gis.638310.n2.nabble.com/Unzahlige-Wege-mit-sac-scale-bzw-trail-visibility-die-komplett-falsch-eingetragen-ist-td5749700.htmlfor
discussion in German).

Reasoning behind this proposed change was the hope to motivate the mapper to
read the wiki to get the meaning behind T4 etc. instead of drawing quick
and wrong conclusions out of the rather misleading textual values of
alpine_hiking etc. So this would be shown in a similar way as tracktype
(grade1-5) in the track template.
Thus we hope to improve the quality of the sac_scale tag, which is in rather
bad condition in some areas.

Please comment if you object to this change JOSM's path template.

Second question to josm-dev: Am I right in thinking that this can be
completely done in launchpad (
https://translations.launchpad.net/josm/trunk/+pots/josm/de/+translate?batch=10show=allsearch=hiking
)?

Best regards,
 Georg

 You want to increase quality by removing information? Are you sure? At best
 you will achieve a decrease in the sac_scale usage.

 If any, add more information to josm, not less. If the description is
 misleading, then change the description. Add examples. Add links to the
 wiki.

 Relying on the users to actively search information because it is withhold
 from him on purpose? Doesn't sound encouraging to me.


I see your point, but if you look at the template it's not possible to put a
long description in the list of values for sac_scale. And the current
information is misleading, so the idea has been better none than wrong.
There is already a link to the wiki at the bottom of the template window,
which links to path and from there to sac_scale.

If somebody can tell me how, I would also add a link to the sac_scale
directly at the list of values for sac_scale, please advise.

And we are already relying on the users to actively search for the meaning
of tracktype = gradeN, so this seems to work ok and is feasible.

I'm also not totally happy with this solution, but we didn't come to any
better one during the discussion.

 Georg

+1 from me.

I would say we need to set up such a system as fast as possible and 
integrate with JOSM and Portlatch.

Otherwise we will end up with lots of data traced with incorrect offsets.

I would opt for submitting bug reports with points and offsets, so that 
there is some review before the adjustments are implemented.


Cheers,
Viesturs
