Troubles & Questions / Online map cache timeout
« on: April 22, 2021, 11:14:35 »
How do I set cache timeout to "never" (or "valid for" to forever)?
Do I set the value in the field to 0, -1, or a very large number?
I can't find anything in the knowledge base.

Maps / Usage = cyclo not English
« on: December 31, 2020, 18:12:36 »
Map usage categories use the word "cyclo" which is not English. How about "cycle" instead?

Discussion/New features / World map at low zooms
« on: December 24, 2020, 12:15:09 »
If I remember correctly, world map at low zooms used to be an option for vector (offline) maps only. Now it applies to all maps.
I want to be able to display overlays such as weather at low zooms. To do this currently I have to turn off the world map display for all types of map.
Ideally I would like to turn on or off the world map display for vector maps, raster maps and overlays separately - and even be able to set the zoom at which it switches. Maybe that's asking too much and I would be more than happy to just allow overlays to appear over the world map.

Discussion/New features / Hill shading intensity
« on: April 30, 2019, 11:12:15 »
It seems to me that the hill shading gets increasingly intense at lower zoom levels to the point where it can easily obscure important map details in hilly terrain.
I have two requests
1. Please turn down the volume control at lower zoom levels so the hill shading is more visually consistent
2. Please introduce an intensity control for hill shading in settings

I use the Locus World base map from the Locus Store for improved speed at low zooms when using vector maps. I note it does not switch in if I am using a Mapsforge v4 map.  :(

3.33 Locus Free "Navigate to" crashes. Both with Brouter offline and Graphhopper online engines. Both via popup on point and button in side menu.
Perfectly ok in Pro version.

Troubles & Questions / Map cache "valid for"
« on: April 28, 2018, 18:26:10 »
I am attempting to use an overlay to display traffic delays and road closures and I can't get it to display reliably..

I have some questions regarding the time validity of the map cache.
1. If I "Set valid for" to 0, does that mean the map is not cached, or that the cache does not expire?
2. Does the same validity apply when the map is used as an overlay rather than a base map?
3. Regardless of the expiry time, is the map cached anyway within the same session of Locus. That is, is the validity of the cached copy only tested when Locus is restarted? To put it a different way, once the map is accessed once in a session, is the same image used until Locus is closed?

Much the same questions apply if I attempt to use an online map with traffic conditions.

Discussion/New features / Inconsistent user interface
« on: April 26, 2018, 12:04:39 »
I think it is time for some consistency in the user interface, particularly with regard to accepting or cancelling settings screens. I illustrate three different screens in particular.

1. Changing info text for a track.

Do I tap the back arrow, or the SAVE text? Answer, no. Hide the keyboard and there's a SAVE button underneath.

2. Choosing available maps.

Does the X on the top right corner cancel? No, it accepts the settings in the check boxes.

3. Accepting terms of use for a map

No, the orange box is not a confirmation button. That's up in the top corner, where it says CONFIRM. And the X means cancel this time.

Oh Menion, let's get this right!

Themes - Vector maps / [Theme] OS Style
« on: February 26, 2018, 16:34:35 »
Just for fun, I've produced a theme that mimics the UK Ordnance Survey styles as far as possible. It's available for free download here.

Troubles & Questions / Backup and restore worked
« on: December 27, 2017, 15:47:07 »
For some reason Locus Pro disappeared from my phone today. Just went.
I reinstalled from the Play Store but all my settings were gone. So, I found the latest automatic backup and did a restore and now all is well!

Troubles & Questions / POI grouping
« on: September 27, 2017, 10:26:06 »
Either I don't understand the Group POI switch in Settings, or it is not working properly.
Looking at an area where there are many POIs, such as central London, I get numbers in circles corresponding to multiple POIs whether I turn the switch on or off.
I am testing with the internal Hike & Bike theme. In the third image below I have circled the markers for multiple POIs

Troubles & Questions / Spurious hill shading
« on: September 22, 2017, 19:13:53 »
Using the latest LoMap of Wales on the latest LocusPro, at zoom=12 only I get spurious hillshading tiles in the sea. There may be spurious hillshading elsewhere, but in the sea it is obvious!
I get the same effect using OAMaps at zoom=11.


Themes - Vector maps / Scaling of dy displacement with zoom
« on: October 11, 2016, 19:27:23 »
In a a pair of lines like
Code: [Select]
<line stroke="#B3A18F" stroke-width="0.6dp" dy="2dp" stroke-dasharray="1,8" stroke-linecap="butt" />
<line stroke="#B3A18F" stroke-width="0.1dp" stroke-linecap="butt" />
the stroke-width scales up and down with the zoom but the dy displacement does not change in the same way.

This code is intended to produce a line with ticks off to one side. As far as I can see, ideally it ought to be:
Code: [Select]
<line stroke="#B3A18F" stroke-width="0.6dp" dy="0.3dp" stroke-dasharray="1,8" stroke-linecap="butt" />
<line stroke="#B3A18F" stroke-width="0.1dp" stroke-linecap="butt" />
with teh displacement and the width scaling exactly the same way.

Themes - Vector maps / [Theme] Voluntary UK
« on: March 04, 2013, 18:22:01 »
The Voluntary UK theme is designed for clarity of display. Its colours are based on UK Ordnance Survey conventions and will be fairly familiar to British users. Even if you are not British, the colours and styles will probably work well for you. It automatically scales for devices with displays of different resolutions and symbols enlarge smoothly for higher zoom levels. The zoom levels at which various features appear has been adjusted to provide optimal information and reduce unwanted clutter.

You can choose Hiking, Cycle, City, Multi, Yellow or Transparent style when you select the Voluntary UK theme.

The styles take advantage of switchable options. Display of hiking, cycle and mountain bike routes can now be switched on or off, as can highlighting for each of them. The number of options shown is relatively limited to aid ease of use. Cycling, Hiking, City and Road styles function almost as presets with a limited range of tailored options. Within these particular styles the display is subtly tailored to its purpose: for example, Road displays junction and road numbers better; Cycling has a better display of cycle routes. Multi, Transparent and Yellow have a fuller (but manageable) range of options. Locus remembers the settings of the options for each style.

The City style is aimed at use in large cities such as London and has a less cluttered (and slightly faster) display at low zoom levels. Colours in the Yellow theme are more muted and are aimed at use with overlays in Locus Pro.

1. Voluntary (Mapsforge version) | 2. Velocity (Locus version)

A "Transparent" style turns off the map background and enables use of a vector map as an overlay on top of a satellite image in Locus Pro. This requires the use of "src atop" blend mode for the overlay map. Similarly the "background" checkbox in the Yellow style can be used to achieve the same effect.

Generally, blue dashes are cycle ways, green dashes represent dual use both on bike and on foot (bridle paths in the UK), and brown shorter dashes use on foot only. Blue blobs are cycle routes, green blobs are hiking routes. Mountainbike trails are shown by violet blobs. Cycle routes are also indicated by blue dashes on the roads. Hiking, cycle and mountainbike routes can be emphasised by selectable overlays.

The theme is designed to work well with both LoMaps from Locus Store and maps from OpenAndroMaps. Footpaths, bridleways and cycleways are indicated on the map by dashed lines where they follow the path of a mapped track or pedestrian way if the map supports it (currently OpenAndroMaps).  Also on maps from OpenAndroMaps, blue dashes on roads are either cycle routes or roads with cycle tracks alongside, while shorter blue dashes on roads show cycle lanes in the road.

The Locus package includes a version that works with Mapsforge v4+ (Multilingual) maps from OpenAndroMaps. This theme only appears when a Mapsforge v4+ map is selected.

Also included in both zip files is the visually-similar Velocity theme for a simpler display with much faster drawing.   

The package is available in two versions, one for Locus maps and the other for Cruiser, Orux Maps, etc.

The Locus version of this theme can be installed easily from the Locus Store in the app. Go to Locus Store > By Usage / Graphic  / Themes - Vector Maps and scroll down to Locus Community / Voluntary UK theme. Alternatively, download Voluntary, below.

For Cruiser , Orux Maps, etc., download, below.. 

From time to time I will update these themes (and reset the download count). The latest version is always in this post.

Updated to show hiking and cycling routes at lower zooms in the respective styles and to improve the rendering of unpaved roads; bugfix version released and download count reset 09 May 2020
