Heute

habe ich einen ersten Vergleich gemacht, um den Unterschied besser sichtbar zu machen. Die Bilder zeigen eine Streckenmessung mit einem Samsung S10-Handy und der gleichen Konfiguration auf dem anderen S20-Aufzeichnungshandy für den separaten GNSS-Empfänger.

Es ist deutlich zu erkennen, dass in den Gebieten, in denen die Randbedingungen schlechter sind, das Mobiltelefon schwächelt und der GNSS-Empfänger im Vorteil ist.

Hier die Beispiele:

Beispiel 1:

- Mobiles S10: https://c.gmx.net/@324496113698608933/WuHjHue5RUeQ9AyBsU7eIg
- Perfect Shot GNSS-Empfänger: https://c.gmx.net/@324496113698608933/QditWyVVT4OQmbpuAVn5Ew

Beispiel 2:

- Mobiles S10: https://c.gmx.net/@324496113698608933/sDB_yH7qTXSmT9ymj6xhLg
- Perfect Shot GNSS-Empfänger: https://c.gmx.net/@324496113698608933/h3kkw4WWTW2F9REXYYGgng

Würde mich über ein Einschätzung und Rückmeldung freuen.

Danke

Hello,

my interest is, to get a more precise GNSS position for the track recording as it is done by the usage of the mobile phone internal GNSS receiver. Background is, that during my hiking tour, specially in mountain, valley and forest regions, the tracking of the position and related altitude is not as precise as I want to have it. One good example is, if you are standing close to the edge of a deep hollow and the measuring point jumps between bottom and top, the result is a altitude calculation, which is far from real.

In a first step, I bought a GNSS receiver from Adrusimple, which allows together with an RTK helix antenna very precise measurements, if the programming is done well, which I worked out over several weeks. I'm using this equipment since month now and I'm really happy with the related results. But: The costs are really high, about 300€ and not really an option for maybe other interested user.

So in the second step, I tried to reduce the cost by using catalog single components and a cheaper U-Blox M9N GNSS chip. After a lot of testing and programming, the new receiver delivers nearly the same positioning quality as the former one. I will now do some further optimizations on the housing and tests in mountain regions. 
If you like, I will keep you informed and show some comparison measurements with simple mobile phone logging afterwards.

I'm looking forward to get some feedback from you side, if you have same experience and maybe interest to get further information details.

Cheers

Hallo wiedermal,

inzwischen gibt es Neuigkeiten....

Fangen wir mal mit der Historie an: Den bisherigen Adrusimple Empfänger, der auch eine RTK Genauigkeit bietet, hatte ich ja bereits "vorgestellt". Ich nutze diesen nach wie vor (ohne RTK Daten Download) und freue mich, über die deutlich bessere Genauigkeit gegenüber einem Handy GNSS Empfang. Natürlich mit Mehrkanal GNSS und deutlich besserer Antenne, als es ein Handy bieten kann. Problem: Für die allgemeine Outdoor Anwendung deutlich zu teuer.

https://c.gmx.net/@324496113698608933/o7FrrIyoRO2bJBvz3TvjnQ

Stage 2 basiert auf einem U-Blox M9N Chip, welcher gleichfalls einiges an Potential mit sich bringt, allerdings deutlich günstiger zu erwerben ist, da er keinen RTK Empfang beinhaltet.
Die aktuelle Basis besteht aus diversen Komponenten, die ich zusammengestellt und dann in ein Gehäuse integriert habe. Nach ziemlich vielen Testrunden mit unterschiedlichen Einstellungen der U-Blox Software des GNSS Chips, habe ich inzwischen eine Programmierung gefunden, die der Genauigkeit des F9P nahe kommt.
Die Optimierung läuft weiter und bei entsprechend positivem Feedbach werde ich berichten, kommende Woche dann ggf. aus den Vogesen.

Würde mich freuen, wenn es Weiterhin Interesse gibt.

Liebe Grüße

Hallo

ich bin auf der Suche nach Gleichgesinnten, die auch nicht zufrieden mit der Qualität der GPS-Positionsdaten Ihres Mobil-Telefons sind, bspw. bei der Nutzung von Locus als Outdoor App.

Ich habe mich daher intensiver damit beschäftigt und nun nach einigen Monaten einen externes Modul entwickelt, welches deutlich bessere Daten liefert.

Ich wäre jetzt für mich damit zufrieden, allerdings könnte ich mir auch vorstellen, es für die breitere "Masse" zu optimieren. Voraussetzung wäre natürlich ein generelles Interesse.

Also: Meine erste Frage wäre daher: Besteht überhaupt der Bedarf, oder sind alle mit der aktuellen Präzision, die ihr Handy liefert, zufrieden?

Alles weitere Fragen würden sich den Rückmeldungen anschließen, wie Details, Kosten, etc.

Ich würde mich über Euer Feedback freuen.

Danke und Gruß

Olaf

I have turned off the screen lock completely. Apparently you can also control the function with Tasker. But I don't need a lock.

Irgendwie weiß ich nicht so richtig was da neue sein soll an Satelliten Karten. Ich kann da keine neue Karten finden.
und was bringen diese ? Ich hatte vorher schon eine Karte mit Satelliten Ansicht. Die war von Google und gibt es schon Jahren. Ich konnte diese als Hauptkarte nehmen oder als Owerlay.

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.

I am happy to get any feedback und suggestions.

Regards
Bernard

Every app which operates with external data (like Locus vs. OAM maps eg) - What is Googles idea here? Only the app itself is allowed to retrieve/store such data? This would be a huge step back (and a huge step towards Apple stupidity).

Hello,
not yet implemented. Suggest voting here to increase priority and watch progress.
Does this basic and useful function really needs votes to be implemented?

All geo App developers should unite and kickk Google's ass.
Now all of them - and their customers and users are suffering separately.

Unacceptable.

Themes - Vector maps / New style: FzOAM
June 27, 2020, 17:44:03
Hello, fellow walkers, runners, bikers, hikers and mountaineers!

While searching for the best map and theme source I've found two great projects:
1. OpenAndroMaps is already a huge one, with well tuned maps and many themes (Thank You!).
Unfortunately in my opinion, none of them was easy to read and/or detailed enough.
2. Freizeitkarte on the other hand isn't that widespread, but is an impressive project (Thank You!).
It is far more detailed and has really good themes.
The only major flaw was that the theme details appear too late when zooming.

I wasn't brave enough to tune the zoom level for every detail,
but tried adding the useful landscape details to the feature rich Elements theme for OAM.
Most of the textures are directly borrowed or heavily inspired of FZK.
The documents and key file are slightly tuned accordingly.
I am providing the result if anyone finds it useful.
I don't have the time and talent to support and develop the new theme.
If someone decides to adopt it, I will be very happy!
Until then I hope You enjoy it.

Happy journeying everyone!

b) I personally even with my quite slim fingers, from time to time incorrect tap on buttons in function panels, so I believe that this increase in width will be a benefit for easier usage.
@menion - also remember/ please don't remove the functionality of config.cfg dev_gui_main_rescale_value setting. Maybe migrate into expert settings. It allows function panel buttons to be increased in size for this purpose.

Also, more importantly, merry Christmas & happy new year to Menion & all the incredibly hard working Locus team, and wishing you all great success in 2020.

So short (5-10 minutes) poll for those of you, interest in future of Locus Map: https://forms.gle/ro1xvZoRjwqTnXCP9 .
A pity there is no option in the poll for zoom buttons positioned as currently along the bottom of screen; when cycling I rest of my hand on the bottom of the phone to stabilize, so having those buttons close to other buttons as proposed increases the risk of tapping the wrong button.

Each question could have an extra text box so the user can provide further comments (as above). Maybe too much information?

PS, I had to think about why that prototype screenshot was bugging me...  Now I know.

There are things covering up parts of the map.  Four round things.  The map to me is #1, it's the reason for the app.  I have Locus set up to show a clean map rectangle, and all the cruft is outside of it, in panels where it belongs.  (Other than scale and invisible [!] copyright, but close enough.)

Also, I like BIG targets for the + and - buttons.  They're quite big now, but those fat round circles in the prototype look smaller and harder to hit, certainly harder with the left thumb.

My two euro-cents...  :)
