Topics

Hi Everyone,

A big thank you to everyone that tried out the recent v20231013 release (it contained a lot of changes I have made over the last 2.75 years!) and thank you everyone for kindly reporting back to me the bugs/issues and things that could be improved further.

I've incorporated the changes and have just updated the sticky "[Theme] OS Map" topic thread with the latest release (see post #1 for updated release notes and details).

I'm hoping I can get this version of the theme into the Locus Map store to make it easier to download and install soon.

[Dedicated cycle lanes]

Not many themes support cycle lanes, my os maps theme and John's Voluntary themes do.

But I've noticed some differences between OAM/LoMap maps and also mine/John's theme when it comes to rendering cycle lanes on one ways highways.

Here is what OSM define for cycle ways:

Dedicated cycle lanes
cycleway=lane is used to tag two-way streets where there are cycle lanes on both sides of the road, or one-way streets where there is a lane operating in the direction of main traffic flow.

In my theme I have options to let the user indicate if they are in a country that drives on the left or right, since the logic of which side a cycle lane should exist on a one-way highway depends on in this.

Wondering @john if you decided not to differentiate for one way highways?

Also wondering if OAM tag transforms cycle lanes differently to LoMap, as there are differences in the results using the same rules...

I guess I'll, have to go through the theme rules with a fine toothed comb to figure out what's going on...

Hi Everyone,

Finally the wait is over. After 2.75 years to I have finally completed the update to the OS Map theme.

Please check the main OS Map theme sticky post for more details.

I found that LoMaps include layer=1 but OAM exclude it. I have to say that I have not found layer tags useful, they tend of mess up the rendering and usually seem to correspond to lazy mapping to quick fix lots of errors in osm.

Attached is an example if a cycleway with layer=1, showing lomap and oam maps rendering a highlight of the cycle routes underneath the highways. In this case the embankment is drawn above the highlight for lomap. The theme draws the. In the correct order to avoid this (embankment, highlight, cycleway)... but (I suspect) the layer tag overrides the theme in this case.

I'm not sure what tag transforms OAM is doing here, their documentation only mentions filtering out the layer=-1 for waterways with tunnel set...

Perhaps filter out layer tag on ways that it should not be used on, as per: https://wiki.openstreetmap.org/wiki/Key:layer

Some points from osm documentation that support this:

With some exceptions, layer=* on way ways should be used only in combination with one of tunnel=*, bridge=*, highway=steps, highway=elevator, covered=* or indoor=yes. For area areas, it could be used in combination with tags such as man_made=bridge, special types of building=* and similar.

Roads, railways, waterways etc. should not be tagged with a layer just because they are raised up on an embankment or are in a cutting - use embankment=* and cutting=*, respective waterway=ditch for this purpose.

I just downloaded the latest England Lomap (4 Sept 2023) and noticed that bicycle route NCN 45 has gone missing.

https://www.openstreetmap.org/relation/22602#map=8/50.917/-6.152

I see that the route was recently edited in OSM and definitely exists, perhaps someone deleted it just prior to the LoMap generation?

I can't view the history in OSM, says it's too large to load...

Can we get this fixed/regenerated?

Best regards
Karl.

Since the new releases of Locus Map 4.15.1 and Locus Classic 3.66.1, both editions are now text wrapping "long" names.

For really long names this is good, but the algorithm is going g a poor job of wrapping also not very long names. Also the wrapping seems to be left justified, and the placement of symbols "below" are not to the bottom/right.

Seems to be only v4 maps affected.

In the past this would occur rare and then stop, e.g. if change maps or restart. But, I've tried restarting and it seems be permanent now.

Attached is an example.

Worst is the Nottingham Hill. Having a single character word wrapped also looks bad.

Can the text wrapping be made a setting? Or improved to of wrap on non-alpha chars?

With v3.64.1 I sometimes find the UI colours get inverted and menus have white text on white background. See screenshot.

I can 'fix' it by opening quick settings (opens in Black, white, see screenshot) and closing quick settings. After that the UI returns to normal white with black text, see screenshot.

I'm guessing this a bug, but also wondering if perhaps dark mode is being developed for classic but not yet released...

I've been working on updating my OS Map theme for LoMaps having improved the OAM version, and discovered that wetland=saltmarsh is not part of the lomap tag mapping. All these areas (quite a lot around the UK coast line) end up as plain natural=wetland.

Another tag I really miss in LoMaps is tidal=yes.

Many footpaths and areas area tagged as tidal and hence only accessible at low tide.

Tidal=yes, is also useful for distinguishing between natural=wetland area that are probably tidal mud flats vs inland peat bogs.

Would it be possible to add wetland=saltmarsh to the wetland tag mapping for LoMaps? And would it also be possible to add tidal=yes

I created this cursor and having been using it for many years. I thought perhaps others might like to use it, so here it is.

the symbols used are:
  - empty red circle when stationary and your position is based on network signal.
  - red circle with small inner circle when stationary and your GPS position is locked.
  - red circle with rotating arrow when you are moving.
  - red cross when you scroll away from your position.
  - simple red/white compass symbol.
  - darkened/smoked field of view overlay is used for the show view option.

See attached preview (note blue dashed outlines are not displayed, just the size/edges of the images).

[Link to latest release:]

The OS Map theme 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 (v3 and v4). I must give credit to John Campbell for his Voluntary UK theme that I used as a starting point (v. 190101).

The OS Map theme also provides a darker variation of OS style of map designed for use at night-time to help avoid spoiling night-vision whilst keeping a recognizably Ordnance Survey style of map.

The theme now consists of four main theme files, day/night for v3 maps and day/night for v4 maps. There are two PDF map legends, one for day and one night.

Here is a comparison of the same map rendered with: Internal Theme, Voluntary UK, OS Style and my new 4 OS map styles:

Added defibrillator symbol (non OS symbols)
Added OS text symbols for: Libraries, Shelters, Cairns, Caves, Adits [Mines, Mines (dis)], Waterfalls (Falls in blue)
Added library buildings to list of important building, i.e bolder outlines.
Added place markers for towns/cities (similar to Elevate theme) at low zoom levels (e.g. 5-7).
Added support for sizing of town/city names based on population density (popcat)
Changed borders (admin_level) to improve support for non-UK counties by grouping togther Parishes=9/10, Districts=7/8, Counties=5/6, National=2/3/4
Changed pharmacy amenity symbol to also include chemist shops (non OS symbols).
Changed order of options, putting least changed options towards bottom of list.
Changed embankments to draw at a higher level priority to avoid them being overdrawn by water ways and residential areas.
Changed footbridges to draw at a higher level priority to avoid them being overdrawn by water ways.
Changed tunnels to use smaller dashes for better match OS map style.
Changed 1:50k trunk_link and motorway_link roads to use correct/matching outline widths on bridges.
Changed highway labels at zoom levels 7-12 to use captions instead of pathtext for OS labels
Changed priorities of several symbols to improve visibility of churches, information and museums at lower zoom levels.
Changed car parks at lower zoom levels (upto zoom 15) to only show ~|destination|customers|public car parks.
Changed hill name sizes slightly larger
Changed (corrected) selection of national hiking routes to only include iwn|nwn, i.e. remove rwn|lwn|uwn.
Changed (corrected) selection of national cycling routes to only include icn|ncn, i.e. remove rcn|lcn|ucn.
Changed (corrected) wells so they now get displayed.
Changed doctors captions from red to black text.
Changed v3 theme place names to match/harmonise to style used on v4 theme.
Removed tourism brown dashed ways accidentally left in from donor theme (UK Voluntary)
Removed access cross hatchings on footpaths accidentally left in from donor theme (UK Voluntary)
Removed surface dashes on 'white' roads accidentally left in from donor theme (UK Voluntary) - If this is going to be in the theme then I need to think about how to do it in an OS style way...

v20200530
Fixed validation errors (one was a real issue in V4 theme for railway stations at zoom 13, rest were technical errors but not impacting display of maps).

v20200607
Split v3 and v4 theme files into separate day and night theme files so they can have different map=background tags, different PDF legends and increase performance.
Added night mode symbols for transmitters, windmills, wind turbines, lighthouses, ruins/archaeological, battlefields, telephones, helipads, bollards.
Added night mode PDF legend.
Added four .lnk files to map the two PDF legends to relevant four theme files.
Changed priority of cemetery symbol lower than church symbol.

Changed night mode tunnels to use own night equivalent of day tunnel colours.
Changed night mode steps to look similar to day time steps and less like a ladder.
Changed night mode turning circles and passing places to be more visible.
Changed area ways for residential roads to match residential road outlines for all map themes.
Changed AED, playground and shooting symbols to remove white outline/background to match other symbols.
Changed 50k toilet symbol to fix errors in tiny-svg rendering.

Added support for LoMap v4 maps to represent "public rights of way" using proper OS map symbology for public footpaths/bridleways, byways open to all trafficm restricted byways, other routes.
Changed for OAM maps to pseudo-represent "public rights of way", i.e. green/pink dashes for public hiking routes, designated footpaths and bridleways (note OAM does not support PROW tags).
Changed default options for 25k to be feature rich, and 50k to be OS minimal features.
Changed "public rights of way" to use slightly large dashes to be more visible and closer in style to OS maps.

Added footpath names visible from Z16.
Changed "surface textures" options to also include all steps, footpaths and bridleways.
Changed option "road surface/grade textures" to "surface textures" to be shorter menu entry.

From v20210216  onwards the theme now supports road surfaces and sealed/unsealed roads:


The theme ZIP files and PDF legends are too large to attached to this post (limit of 2MB) so, I am now releasing everything via a shared google drive folder:

    OS Map Theme Releases

Link to latest release:

    OS Map v20231218.zip

Links to the latest OS Map Legends:

    OS Map Day Legend
    OS Map Night Legend

The theme is now provided in a ZIP file form that can be simply copied into Locus Map's _theme folder, e.g.:

\<root>\Android\data\menion.android.locus.pro\files\Locus\mapsVector\_themes (i.e. for LM Classic)
\<root>\Android\data\menion.android.locus\files\Locus\mapsVector\_themes (i.e. for LM 4)

No need to unzip the theme file anymore.

If you have already started using the earlier OS Map theme version then you probably should delete it before installing this updated version as it uses the same theme folder called "OS Map" but now uses four different named theme files - to cover day/night themes for v3/v4 maps.

Note that the legends are now included in the theme and can now be viewed directly from the theme menu in LM 3.46+ via a long press of the theme icon, see attached screenshot.

From v20231218 onwards, the theme now includes support for public rights of way (currently only LoMap v4 maps). There is now an appendix in the PDF legends that explains how these are interpreted, which is mostly UK specific:

Is it possible to change the colour of the undrawn/Loading tiles?

I have a theme for night usage that uses darker colours but when I scroll the map my night vision is blasted by near white undrawn tiles, see attached example.

I know the LM night mode uses darker undrawn tiles, but it also inverts the colours.

Is there a way to use layer options and apply things based on both when the layer is selected and something else when the layer of NOT selected?

In my OS Map theme I have an option to display road labels similar to OS maps as path text along the side of the road. For single carriage roads this works fine for both left and right drive maps/counties.

However, for dual carriage ways I have used a DY setting for the path text that places the road labels to the left of the road for left hand drive maps/countries. In right hand maps/countries the offset is wrong and the road labels appear on the roads instead of to the side:



The left is UK left hand traffic and the right is Germany rigth hand traffic with labels in wrong place...

I thought I would use a layer option to allow you to indicate if you want right hand traffic or not... if not, then I assume left hand traffic. I would then use a positive or negative DY offset based on selected or not:



Anyone know if this is possible?
thanks
Karl.

PS: Yes that is a v4 map and yes the OS Map theme for v4 maps is very close to ready...

In the following post I used a script to semi-automatically convert the Waymark-V2a LoMap theme to be compatible with the MF v4 map theme renderer, i.e. so it would "work" with v4 maps:

https://forum.locusmap.eu/index.php?topic=6948.msg59452#msg59452

I used the Waymark-V2a theme purely as a test of the script as it is quite a large theme file, and it "worked" with v4 maps, in so much that it is displayed something. However it was pointed out that it didn't display the hiking trails, cycle routes or waymark symbols.

I started to look at why and realised that the Waymark-V2a theme was developed purely for Locus Map maps and did not appear to support OAMaps. I have made some further tweaks to the converted version from the link above and got the cycleways, hiking routes and waymarks to display now. You can also select/deselect the hiking/cycle routes. However, I do not think it will be possible to deselect waymark symbols for specific OSMC colour routes. For now, the theme only switches on/off all waymark symbols. Also not finding a way to not show trails when waymark routes are selected - other than overdraw the trails, but the route labels still show... so I left it alone for now).

I've not packaged it up into a ZIP with all the resources yet, because it is really just an experimental theme at this stage which will require some more testing/feedback, especially considering the original is set up for LoMap tags and not OAMap tags. There will probably be many other missing items for this reason. Probably a Waymark-V2a user will spot them very quickly!

To try it you will need to have the Waymark-V2a theme already installed and also a v4 map that supports OSMC waymarks (the UK maps I use do not).

You just need to copy the attached Waymark-V4a.xml and Waymark-V4a.png files into the same directory as the original Waymark-V2a.xml theme file is stored (will depend on where you chose to install Locus Maps I suspect).  Will be something like:

/storage/6345-6342/Android/data/menion.android.locus.pro/files/Locus/mapsVector/_themes/Waymark-V2a/
/storage/emulated/0/Android/data/menion.android.locus.pro/files/Locus/mapsVector/_themes/Waymark-V2a/

I'm wondering if there is any point using the Waymark theme, now that Elevate 4 supports Waymarks...

I've been testing out my partially completed  v4 theme and tried it with the ML v4 Rheinland-pfalz map. This map appears to behave differently from others I tried. On this map the map-background set in the rendertheme tag is used for most of the background.

This is not a major problem for most themes, except for my theme which relies on k="natural" v="nosea|land" being used to provide full coverage of land because the theme uses a darker background for the "night mode" card.

Attached are a couple of screenshots showing map-background set to #800000 and the other #f8f8f8 using my theme so far. However for night mode I need the background to be #373737.

I also tested map-background on OutdoorV4 and got the same results.

Anyone else spotted this on some maps?

Is there a way of varying the background on maps like these? or is the map-background setting always used. If this is the case, then I will have split my OS Map theme for v4 into two separate themes, one for day and one for night...

At the moment I'm converting my OS Map theme from v3 to v4. I have been finding the process very mechanical and repetitive, so much so that once I I done around 2,500 lines out of 10,000 lines by hand I decided to quick put together a script to do most of the changes programatically. 

Attached is a VBScipt that does most of the changes required to convert a v3 theme to v4.

I quickly discovered that  v4 render engine is very intolerant to syntax errors and if any are present it will refuse to display anything. This means manually removing parts of the generated v4 theme until it works and locating the syntax error. The following are some examples of errors I found in several themes:
   - stroke-width="1.2p"
   - <rule case="off_pl"
   - close="yes"  (should be closed="yes")

I have converted the following themes using the script, in some cases requiring some additional custom mods:
   - OS Map
   - Outdoor (because it is small, simple and already has a v4 theme to compare with)
   - Waymark2a

I would consider the output of the script as a starting point only and not a final theme. In some cases it is possible to tweak the theme using the script, see the Outdoor script for an example. In some cases there are differences that have to manually changed in the generated theme. Waymark2a is an example of this, seems the v4 rendering in LoMaps has a bug, the following puts green dashes on service roads as well as raceways:

<rule e="way" k="highway" v="service|raceway" zoom-min="14">
   <line stroke="#ffffff" stroke-width="0.81" />
   <rule e="way" k="highway" v="raceway" zoom-min="14">
      <line stroke="#a5cba5" stroke-width="0.54" scale="all" stroke-dasharray="1,1" stroke-linecap="butt" />
   </rule>
   :

so I had to manually separate service and raceway rules to fix this:

<!-- service raceway -->
<rule e="way" k="highway" v="service" zoom-min="14">
   <line stroke="#ffffff" stroke-width="0.81" />
   :
<rule e="way" k="highway" v="raceway" zoom-min="14">
   <line stroke="#ffffff" stroke-width="0.81" />
   <line stroke="#a5cba5" stroke-width="0.54" scale="all" stroke-dasharray="1,1" stroke-linecap="butt" />
   :


I'll add the converted Outdoor and Waymark example themes in the next few posts. I'm using the initial conversion of my OS Map theme as a starting point for a v4 OS Map theme. I'm about 50% complete so far, but am battling with lack of symbol and text scaling in v4...

Please note that this script is a quick hack, there are probably better ways using XML libraries to do this... It does no error checking and you'll probably need to modify it for best results. It is a visual basic script and should work on a Windows command line using the following command line syntax:

     cscript v3_to_v4.vbs <v3 rendertheme>.xml <v4 rendertheme>.xml

Where:

        v3_to_v4.vbs                 -- Name of this script
        <v3 rendertheme>.xml         -- Input file that is a v3 rendertheme file, e.g. VoluntaryV3.xml
        <v4 rendertheme>.xml         -- Output file to be created as a v4 rendertheme file, e.g. VoluntaryV4.xml


Just putting this out there in case it is useful to other theme writers. It isn't really suitable for most people to use, but anyone with a basic understanding of visual basic and renderthemes should be OK.
I would check the examples in the following posts for examples of how to use the custom coding section and supporting functions...

Karl.

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.
