This bundle is blatantly based on the work of others, and the name pays homage to the Volatile set of themes. The colours of the roads are tuned to UK Ordnance Survey conventions. Hiking and cycling routes are shown by simple coloured blobs (green and blue respectively) along the roads and paths involved (if the map supports it, like OpenAndroMaps or the vector maps from Locus Store).
The zip file includes a basic key to roads and paths.
There are quite a few other tweaks, (such as changed order of some rendering; changed patterns for allotments, orchards, nature reserves, private access roads; semi transparent woodlands and other areas; changed rendering for canal locks) which I failed to document as I was going along.
From time to time I will update these themes. The latest version is always in this post.
There is a bug in the MapWriter engine that produces extraneous vertical and horizontal lines at certain zoom levels where the „way“ is closed (such as a raceway, airport perimeter track, and certain road layouts). This revision of the Voluntary bundle includes themes that attempt to fix this bug for raceways, runways and taxiways and unclassified and tertiary roads, although they do introduce other minor artefacts for the roads. Each zip file includes a version that fixes the „spurious roads on tile edges“ bug, but generates other minor artefacts at zoom 13. Locus version is for Locus app, Orux version is for Orux and other apps like Cruiser, Atlas. Versions that leave the roads unfixed are also included in the zip for downloadNovember 28, 2014 um 12:12 #3203
Contrary to what I wrote in the original post, the latest version of the theme is in the last post, as I cannot edit the first post.
Today’s update:bugfix on unclassified highway areas on bugfix versions. Also rendering of dams changed.November 28, 2014 um 14:25 #3257
Sorry for any inconvenience, I forgot to allow deletion of attachements for the author.
These privileges should now be granted – please give it a try.
Thanks, ChristianNovember 28, 2014 um 16:04 #3258
What is the difference between delete and detach, the two options I am offered? They both deleted files from the first post.
What I was hoping for was the ability to update the attachments in the first post, which is a common way of dealing with downloads.November 28, 2014 um 17:59 #3264
Detach leaves the old files on the serverNovember 28, 2014 um 18:48 #3265November 28, 2014 um 21:21 #3267
You are right.
The procedre should be: delete the olsd attachements, make a new post and give the new posts the same names for the attachements as for the ols ones.
This would make it posssible to create „install“ buttons for Orux and Locus cause the urls would be the same.
Well – for serious purpose it would be necessary to add a page like the ones from Tobias…..November 28, 2014 um 21:30 #3268
I believe I deleted two of the original files and detached one, but the new uploads were all renamed with an extra „1“, so I’m not sure how the new files can be uploaded with the same name as the original ones.März 2, 2015 um 21:31 #4138
The Locus version is now fully scalable for different resolutions, with totally redrawn symbol set. Atlas version is designed for Emux’s Atlas but has not been updated this time round.
This theme is intended to work well outdoors, and so has high colour contrast.März 2, 2015 um 22:09 #4142
Very nice work!
Have you considered to use also SVG resources in your themes?
We support now SVG in Mapsforge for both Android and Java.
About the closed ways, the last versions of map writer have several fixes (I remember a similar report).
Do you still see the issue you mentioned in your first post?März 3, 2015 um 01:01 #4143
The artefacts with closed ways are still there in the latest version of Atlas but solved (or at least worked around) with my „bugfix“ version. (See RAF Croughton airfield at 51.98806394040123,-1.1814135346412735).
I made an svg version of my theme for Locus, but it was interminably slow on my Android. As Locus caches the png symbols at the correct size for each zoom, it seemed a better solution, and far quicker, to create large bitmaps and let Locus rescale them. Perhaps I should make the svg version available for people with faster machines.März 3, 2015 um 08:13 #4144
The artifacts issue is actually on the map-writer side. So it depends on the map files (Christian can say more).
The relative discussion in Mapsforge mailing list is here:
We have not seen any performance issues with SVG render themes in official Mapsforge.
There is already SVG cache (memory and file) in use.
(For Java SVG you’ll need currently Atlas Beta)März 3, 2015 um 10:15 #4147
I still get the artefacts on both Locus and Atlas using the latest Great Britain map from this site. My „bugfix“ theme is only a workaround to hide some of the worst aspects of this bug. It’s not a solution by any means.
There was a small bug in the Atlas standard version I uploaded before, so here are the correct files.März 4, 2015 um 22:37 #4155
The Atlas themes now includes a svg version, as suggested.
Locus fails to display all the svg symbols correctly, so this is only available in the themes for Atlas.März 5, 2015 um 09:11 #4157
Thanks for the SVG theme!
AFAIK Locus uses a modified Mapsforge so I cannot comment its SVG rendering.
I tested also with Cruiser (latest Mapsforge release).
It’s worth mentioning that Mapsforge SVG rendering is performed with different readers in Android / Java.
If you’re interested to advance more your render theme, you can introduce style menus.
You can check the Mapsforge wiki about that (see also Elevate preview):
