Themes - Vector maps / [Theme] OS Map (v20200427 for v3 maps only)
« on: April 19, 2020, 01:38:58 »
Having used UK Ordnance Survey (OS) maps all my life, when I started using Locus Map I was desperate for a map theme that looked similar. After using both Voluntary UK and OS Style themes for a while, I still hankered after something closer to the style of the original UK OS maps. So I decided to create my own theme that tries to emulate the Ordnance Survey 1:25k and 1:50k map styles as closely as is possible within the constraints of Locus Map and data provided by the vector maps. It should work with both LoMap and OAM maps. I must give credit to John Campbell for his Voluntary UK theme that I used as a starting point (v. 190101).

There are 6 maps styles provided in the theme:
  • Explorer 1:25k
  • Landranger 1:50k
  • Dynamic Scale
  • Night Mode 1:25k
  • Night Mode 1:50k
  • Night Mode Dynamic
Dynamic Scale automatically switches from 50k to 25k at zoom level 16.
Night Modes provide a darker colour scheme for night usage that preserve the OS colour, but muted a bit. I don't like the built in night mode as it inverts all the colours.

There are also several overlay options:
  • non-OS  symbols
  • non-OS road furniture
  • demanding paths
  • hiking routes, national
  • hiking routes, local
  • emphasise hiking routes
  • cycling routes, national
  • cycling routes, local
  • emphasise cycle routes
  • fill in residential areas
  • grow 50k buildings into town masses
  • emphasise land access
  • OS style road labels
  • level road labels
  • boxed road labels
I used google translate to define the translations, so let me know if there are more appropriate translations.

I also created PDF legends for the 25k and 50k themes to show what is supported/different using a similar style to the original OS legends with screenshots from Locus Map and the theme's own symbols etc.

Last attachment is a ZIP of the theme. (now with .nomedia files, thanks Henk van der Spek for pointing that out).

Install in the usual way of unzipping in Locus Map's _theme folder, e.g.:

\<root>\Android\data\menion.android.locus.pro\files\Locus\mapsVector\_themes

I've only tried this on my phone (Samsung Galaxy A3) and tablet (Samsung Galaxy Note 10.1 2014). It is quite a big theme file now (~10,000 lines)  because it contains so many different categories and overlay options. I am interested to know if it works OK for everyone. I have considered creating a "lite" 25k only option to see it is works faster or not...

I am putting this theme out there as I feel it might be of interest to others. It is provided as is.
I am not inclined to spend a lot of time working on it, but you are welcome to modify it for your own purposes.

Let me know if there some major problems with the theme.

Here is a comparison of the same map rendered with: Internal Theme, Voluntary UK, OS Style and my new 4 OS map styles (also attached as ThemePreviews_LORES.jpg but lower resolution):

UPDATE 2020.04.27
I have fixed:
   - couple of  mistakes in the legends
   - added to the legends some additional overlay footer notes.
   - country borders to include admin_levels 2, 3 and 4 now.
   - rounded locks in rivers now square
   - some syntax errors I found during porting to v4 (which is now about 50% completed).

I've updated the attachments with new versions, hence their counters are reset.
