Quote from: john_percy on March 21, 2023, 00:26:382. What advantages will these latest maps have over OAM ones, particularly if you collaborate in unifying tag mapping etc.?

For me, I see the advantage that LoMap will have over OAM is they will include different tags, e.g. designation (PROW at last!), building=cathedral, horse, and (to be checked, but hopefully) a carry over of the combined network names when they follow the same sections of ways.

Point 13
I have also noticed that LoMaps draws the coastline differently, sometimes pruning parts of the land off. Perhaps LoMap coastline is using some method similar to residential landuse?

The result seems less accurate.

See attached example, bottom is OSM, left is OAM, right is LoMap.

Point 12
Since my theme for v4 is currently targeting OAM I am naturally comparing how OAM abd LoMap v4 maps differ.

I've just remembered that landuse for residential areas is very different in Lomaps, which provides "lm_landuse". This tag uses its own method to establish residential areas, but this results in rather approximate areas, see attached which compares building up residential area using various landuse values (RED) in OAM vs using lm_landuse in LoMap (BLUE).

Can we have the missing landuse=residential tag value?

1. The latest beta (4.15.1.2_1097) downloads but won't install for me. Do I need a gold or silver subscription?
EDIT: Aha! The latest "normal" version which I have installed is a higher version number.

Point 11
I'm missing a lot of tidal mud areas around some of the British coastline, see attached comparison of OAM vs LoMap v4.

OAM have mapped natural=mud + tidal=yes to be treated the same as wetland=tidalflat.

Can something be done to include mud+tidal in LoMap v4 maps? E.g. treat as wetland=tidalflat, or include natural=mud + tidal=yes...

Point 4
- the LoMaps V3 was generated as 512x512 tiles and zoom or area is really "shifted" in comparison of 256x256 V4 tiles. There were minor changes in `zoom-appear` attribute for some elements. But it was mainly for zoom-levels 9 - 10 (I think). Do you have some specific requests to change the zoom-appear for certain elements?

Point 7, re:Point 4
In OAM most of the natural land features (that can cover large areas) appear from zoom level 12, but in LoMap v4 these are appearing at later zoom levels:

From Z13: beach, cliff, desert, fell, heath, marsh, scree, shingle, valley

From Z14: barerock, earthbank, grassland, sand, rock, wetland

Can these appear from Z12? In fact OAM has sand appear from Z10.

At the moment the map goes very bare when zooming out from Z13/Z14 compared to OAM, see attached.



...and few more requests...

Point 8
Can we include "surface" tag for "highway" and "natural" elements?
I think only tracktype is included, but often only "surface" is set in osm. Being able to differentiate sealed surfaces is very useful to many map users (e.g. using pushchairs, cycles, wheelchairs).


Point 9
Is it possible to include 10m contours? And make contours appear earlier too? E.g. major from Z9, medium from Z10,  minor from Z12.  See attached for comparison of LoMap v4 with OAM at Z12.


Point 10
Can we have "peak_dist" available, this allows the theme to bring peaks into view in sensible order and avoid cluttered view, also to have text size varying based on peaks significance, see attached example, note how LoMap v4 map has all peaks same size font. Note that peak_dist values need to override the default peak appear zoom levels to introduce peaks gradually from Z9 to Z12, see OAM tagmapping file as an example.

@voldapet

Thank you for raising the PR.

Regarding: Point 5

John's JohnThorn maps are raster maps, so there is no theming possible within the LocusMap app...

the OAM maps now include (for UK maps) an additional tag:

<!-- OS_OpenData -->
<osm-tag key='os_open_data' value='crags' zoom-appear='13' />

which renders the OS crag data, so from a theme point of view it is very simple to include... but of course there (presumably) was some considerable scripting effort for the map generation to merge in the OS open data.

Attached is an example of using OAM maps before and after OS crags were included.

Some initial thoughts from me:

Point 1:

I see bicycle=designated is added.

Could we include the following?
   - bicycle=no|yes|designated|permissive
   - foot=no|yes|designated|permissive
   - horse=no|yes|designated|permissive


Point 2:

In the UK we have footpaths and bridleways that are legally protected and signed along their routes - these are known as Public Rights of Way (PROW).

OSM has inluded tagging for these ways (designation):

   https://wiki.openstreetmap.org/wiki/Key:designation

and has the following guidance for usage:

   https://wiki.openstreetmap.org/wiki/Access_provisions_in_the_United_Kingdom

Would it be possible to include this designation tag in LoMap maps?

For the UK, the following values would be useful: public_footpath, public_bridleway, restricted_byway, byway_open_to_all_traffic.
The following values are also used in Isle of Man: access_land, public_cycleway, green_lane.
The following values are also used in Scotland: core_path.

This would provide a massive improvement to be able to indicate footpaths that are of interest to hikers, cyclists and horse riders:
   - bridleways can often be part of a highway=track + designation=public_bridleway - these are currently not displayed in LocusMap but are quite common.
   - bridleways (in the UK at least) are also legally accessible for cyclists - some are sealed and useful to road-bikes but some not and need off-road bicycles.
   - many footpaths in OSM are foot=designated but only because there is a general (Cycle|Foot) signage used by the councils to indicate a shared space footway - these are publicly accessible paths, usually pavements, cyceways, side_walks, combined cycle lanes and footpaths - most are in/around towns. They are not PROW but if rendered as "footpaths" clutter the map with many "additional" paths, resulting in a "can't see the wood for the trees" situation for the walker...


Point 3:

Car parking amenities seem to be growing in OSM over the last year, to the point that the maps are starting to be cluttered with many additional parking=side_street.

Could you include the parking=* tag to help identify which car parking amenties are dedicated off-street parking from the many on-street packing, see:

https://wiki.openstreetmap.org/wiki/Key:parking

This tag is also useful for being able to indicate multi-storey and underground car parks.

When combined with access tag, it allows to identify those car parks that are publicly accessible and likely destinations for people arriving somewhere to park.


Point 4:

I see that many of the appear-zoom levels have been tweaked, some appearing much later...

I noticed when we went from v3 to v4 for OAM that there is a difference in visual scaling between LoMap and v4 maps of the same zoom level.
e.g. zoom=16 in LoMap appears similar in scale to zoom=15 in v4 maps.
This has the effect (for the user) that symbols/ways seem appear much later in v4 maps. When you zoom out in v4 maps you seem to get less information compared to when you switch to LoMap.
...so I was a little surprised to see some appear-zoom levels being increased for some tags...


Point 5:

The OAM maps have recently added OS crag data available from  OS open data. I think Christian did some magic scripting behind the scenes to make this possible for OAM and it is a massive improvement for UK maps.
Is this something that might be considered for LoMap v4?


Point 6:
In OAM maps the map tagging separates out common tag values, e.g. foot=yes and bicycle=yes are transformed into foot=ft_yes and bicycle_bic_yes.
I'm wondering if this is something that is desirable for LoMap v4 maps?
I'm not 100% sure why this was done, but is does mean that you can OR together many tags and check for specific instances of common values like ft_yes or bic_yes.
Perhaps this is now resolved with the bugfix to the double tag issue mentioned earlier?

Hi guys,
finally, after years, we are preparing LoMaps based on the latest MapsForge V4 library.

Useful info (numbered so it may be easier to ask for additional info if needed).

1. Required Beta version 4.14.2.3+: http://bit.ly/lmVersionsTest

2. App contains the latest public code for MapsForge lib. So not the latest official 0.18.0 version, but 0.18.0 + latest changes and fixes: https://github.com/mapsforge/mapsforge/blob/master/docs/Changelog.md#new-since-0180

3. LoMaps, for testing of the new theme (currently only Europe) are prepared here: http://bit.ly/3IFmOS4

4. Public repository with the latest "LoMaps offline theme" and also tagging file is here: https://github.com/asamm/lomaps-mapsforge . Seems that @voldapet has to add some "readme".

5. You may notice that themes contains also a separate "poi" theme. This is a special addition currently only for internal LoMaps that affect the display of offline LoPoints (the base map theme does not contain instructions for the LoPoints icons at all). If interested, I may add support for this for public themes as well.

6. The New MapsForge library contains many useful improvements and also some fixes that may be interesting for overcomplicated hacks that are done in OpenAndroMaps regards colors (more here: https://github.com/mapsforge/mapsforge/pull/1366 )

7. Here also comes the idea to unite tag-mapping-xml for main MapsForgeV4-based maps. This should make a life for all theme creators so much easier. What do you think, mainly @Tobias?

8. I would also like to notify all map creators who have themes created for current V3-based LoMaps (and others) about this, namely: @john_percy , @Magellan , @karlchick , @LocusUser#1 , @Tobias, and others ...

9. And the last. If you notice any issue in the rendering system for V4 maps, feel free to ask me as well. I may help here a little bit.

10. New maps are not compatible with current public maps, so auto-loading won't work between them.

Uff, hope this is all. Thanks for reading and testing if someone will want to try it  ;)

In many weeks of testing I have developed a Windwos batch script to generate maps for Locus which are very close to maps probided by OpenAndroMaps. This script enables you to generate a topographic map for any area of the world.

The script and all necessary software will run on a "normal" Windows 10 PC. All details will be found on my website. Although the website is in German, you can translate the most parts easily and the script inself is mostly in English. You will find download links for the map-generation-script, all necessary other scripts and download links for all software packages.

The maps generated with this script will be named OpenOutdoorMap (OOM) . There is also a test-map for download.

https://www.maiwolf.de/openoutdoormap

I am happy to get any feedback und suggestions.

Regards
Bernard

Themes - Vector maps / [Theme] OS Map
May 29, 2020, 17:45:48
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:


SCROLL TO VIEW THE COMPARISONS >>>>

Here are the list of all the changes made for each release:

v20200427
Initial release for v3 maps only

v20200529
Added v4 map support
Added option to highlight toll roads (default is not highlighted). Highlight means orange outline and orange dots as you zoom in.
Added option to set OS style roads names (pathtext) for countires that are left hand traffic or right hand traffic. This is only applicable to dual carriage ways.
Added drawing of footpaths and bridleways that are on dashed track/service roads.
Added thicker dashed 1:50k style for airport runways (was using thinner 1:25k for 1:50k before)
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 track core colour to match service/residential roads.
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.

v20210103
Added cycle lanes and cycle tracks with display option "cycle lanes/tracks".

Changed emphasise hiking routes highlight colours, green for national and yellow for local.
Changed emphasise cycling routes highlight colours, red for national and blue for local.
Changed (renamed) option "left/right hand traffic road labels" to "drive on the left/right side" as this option now also affects oneway cycle lanes/tracks.

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.
Changed buildings in 25k views to merge as you zoom out, avoids clutter of lots of small buildings.

Changed priorities of various symbols to prioritise those that align with OS map conventions first.

v20231218
Removed residential roads from filled in residential areas at zoom level 12.
Removed unused categories and tidied up style menu definitions
Added colour icons to style menus to indicate options by colour groups, green=hiking, orange=cycling, purple=mtb, brown=urban, black=roads, white=non-OS.
Added option "Show symbols earlier" so you can have less symbol intrusion at Z15 and lower, useful in urban/city areas.
Added option "Building names earlier" so you can have more building namers appear earlier from Z16 onwards.
Added option "emphasise all sealed roads too" so you can selectively also highlight ALL roads that are sealed, or disable (if you prefer a less distracting urban view).
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.
Changed option "emphasise road surface/grade textures" to "emphasise surface textures" to be shorter menu entry.
Changed size of covered reservoir symbol at Z13/Z14 to be smaller.
Changed unclassified roads to appear from Z12 (was Z13).
Changed smaller service roads to appear from Z13 (was Z12).
Changed 50k pylons to be smaller at high zoom levels.
Changed place name priorities to work better.
Fixed missing bridges casings at Z13/Z14.
Fixed symbol/pattern filenames to be have matching cases in both theme and filing system - enables theme to work correctly with OruxMaps.

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:

Map Points Trimmer v3.3.2

The aim of this utility is to help transfer your map points with photos in their descriptions from one program to another one so that embedded photos will be properly displayed according to your wishes and screen resolution as preview and have the ability to be magnified by click. Also you can set any path to your photos within any device, delete outdated garbage from descriptions and so forth.

To be short, the main bonus for Locus Map is to get pictures right in the description body and/or as the attachments.

Initially this program has been developed as a self-education utility for quick transformation a huge database of my own map points before transferring them between Locus Map Pro and Google Earth Pro on desktop forth and back.

Then it was added with some more features and I decided to make a design and let others to use it as it may be helpful for someone.

Ideally all this has to be made as a separate site page on a server but I'm not interested in having a hosting and for now the utility is being proposed as it is.
Use it at your own risk  8)
