Maps / Universal world map

@Michael: thanks - are your latest versions available elsewhere?

Hello John and all interested parties,
once the new release is complete, it will be hosted on Christian's site, like the old overview maps.

But here is a link to the ZL 8 map, which is mostly stable (only some rogue elevations in OSM in Alaska and the Philippines (in feet, without notice) keep changing the most isolated peaks there, while I correct the elevations round by round based on Max' SRTM-OSM comparison):

And below is the draft of the text for the overview page (google translate, not yet redacted).

Enjoy and I'm interested in your feedback.


January 2018:

Overview maps with more information
What is common in comparison to the 2016 edition: different zoom levels are different
Data sources used, and the file size remained in the same order of magnitude.
And also the basic format: these maps are NOT vector maps because they react too slow in low zoom levels, conventional bitmap maps
Here are much faster - the undisputed domain of vector maps is now the detailed resolution higher
zoom-levels. However, now only one format, MBTiles, is offered, which can be displayed equally by the essential apps.
As is usual with all cards here, there is a button for the quick installation directly on the smartphone for Locus and Oruxmaps.
What has changed? The more or less random presentation of OSM data (e.g., locations) in the rendering and map generation tools
is simply a nuisance. Therefore, I have explicitly included the selection and control of the objects to be displayed and highlighted in the generation process of the overview maps.
But for a better end result, this presupposes a (mostly manual) editing of the OSM raw material.

So far, the following information has been prepared:
- The main places of countries, provinces and sub-states of many countries are highlighted in 3 different colors, in English and the national language (if that name is significantly different.
- The display size of city names increases in steps with the number of inhabitants (if specified in OSM, hopefully correct, otherwise an assumption is made by location category (city, town, village)). These location size categories are now also included as a "PopCat" tag in Christians OAM maps and can be used by theme for interactive selection. An adapted Elevate theme is on my list for 2018 - maybe Tobias is faster too: -)
- Islands or groups of islands, especially the remote ones, are often hard to find, and there is also a remedy here.
- Inspired by a discussion on the appearance or visibility of mountain peaks operated by Christian and Tobias, and with helpful data tables from Max, I have highlighted some 100 important mountain peaks
- The deepest sea trenches have also been around for a few days.

The idea behind all this is to have selected information available at a glance, OFFLINE. A supplement to Wikipedia, so to speak, which also exists offline: Kiwix and Aard2, both of which I highly recommend.
In the case of settlements, information maximization here means: it is not simply selected by size, but a certain amount of settlement names is packed into a surface. For Alaska or Siberia then show up with less than 100 inhabitants - and they are important because they are the only ones - while in Japan at the same zoom level some 50,000-inhabitant city finds no place. In general, overlaps are NOT avoided, but names of places of larger category always cover smaller places. If it gets tight, this too is an indication, and 1 or 2 zoom levels further, the names of the places are completely legible.

Discussion/New features / WikiLocation feature and alternative

Hi Menion, just wondered if you took the WikiLocation databases from Ben back in 2014 ? Or would you consider using the new and supported and official Wikipedia API that Ben mentions in his services termination post of 2014 ?   TXs and cheers from France Michael

I did a series of routings for vacation planning and found that only one out of 10 or so targets appeared in the recently used list.
Can this pls. get fixed ?
TXs and cheers

Troubles & Questions / FC when deleting point from Appalachian trail
« on: September 03, 2016, 07:41:36 »
Hi all,
first observation is that Locus creates 1000s of arrow down icons while importing the trail tracks. The 10s of POIs are handled properly, and the track itself is valid, too, but for each segment Locus creates a useless point in addition. 1000s. Trying to delete one, Locus cycles forever and ends up in FC.
The issue I see is the amok import exercise in the first place.

Selecting the option Merge points with track will lead to long running import, that delivers only the extra points, but NOTHING from the track.

The GPX I use comes from here:

Moving from one Country to another correctly swizches maps, but the name displayed in the top bar stays with the map of the old place and only switches to the correct name at zoom level 15 or so.

Troubles & Questions / Geo based access to Wikipedia
« on: May 22, 2016, 12:18:39 »
Hi Menion, I am on Sicily and face on gap in the information flow chain:

Locus shows a map section, all offline, I select search, then the Wikipedia of interest (language)   and then access to the Internet is needed. Once the list of nearby matches is presented, you can continue offline by using aard 2 app and SD card DBs. 
I saw you are using an older DB from Ben D.
Could this DB be downloaded and evaluated by the Locus app itself ?

TXs and cheers

Fortsetzung von
in deutsch.

Hier meine Antworten:

Kann man vielleicht auch die Google Map unterlegen? ja - App Locus-addon Map Tweak hilft.

Wie kann ich während der Navigation eine Adresse, einen Punkt auf der Karte o.ä. abfragen u. dorthin navigieren? Während einer Navigation ist Locus weiter normal bedienbar, inkl. Adress-Suche, Punkt-Infos etc. Wenn Du dann dorthin navigierst (via > Kontextmenü, ist die alte Navigation natürlich tot. Probiere die Details einfach einmal aus.

Was hat es mit der Gültigkeit der Karten auf sich? Die wird von Locus nicht überwacht (d.h. keine automatischen Updates), und auch nicht limitiert. Ich nehme an die Frage geht um Offline-Karten. Bei den LoMaps von Asamm gibt es eine zeitlang Updates. Aber ich nutze praktisch nur die OpenAndroMaps-Karten.

Was heißt Karte neu initialisieren? Was ich mich natürlich nicht traue, weil da steht "own risk". Wo kommt diese Funktion vor ? Habe sie bisher nie gebraucht.
ist übrigens der Einstieg zum Benutzerhandbuch (CZ, E, D).

Schöne Grüße

Troubles & Questions / Tracking start stuck in "working" message

Even after hours no way to get back control. Reboot needed.

Troubles & Questions / Hill shading and HGT downloads
« on: March 15, 2016, 21:14:54 »
Tried Hill shading for areas for which I do not yet have the HGTs on my SD.
Funny effect: the HGT covers more than shading is displaying. But the dynamic elevation does recognize and display the value. I attached a typical situation.

Troubles & Questions / POI DBs not recognized
« on: January 22, 2016, 01:35:52 »
From earlier times I have many POI DB files along the OAM map files in mapsvector folder. In the past Locus recognised them all,  regardless of available map files and their names.
Since a while a POI DB file is only recognized if there is a map file with the same prefix name. E.g.  and austria.osm.db will show you the austria.osm POI file in the selection list. If there is only,  you will not see austria POI file. This is obstructive and not justified. POI DB should work even with online maps and not a single offline map. Pls. do not take your users hostage of the Locus vector map store.
Thank you.
