I am developing a real-time location tracking website that works with Locus Map. The current workflow is as follows: the Locus Map app periodically sends user location data (including longitude, latitude, altitude, nickname, etc.) to my server, and the server is required to return a response upon receiving this data.

I have tested responses in both KML and GPX formats, and Locus Map can parse and display them on the map without any issues. However, I now wish to use JSON format for the server's response, and I am unsure whether Locus Map supports directly parsing JSON-formatted response data.

If it is supported, what specific fields are required in the JSON response? Is there any official documentation or example available for reference?

Vážený týme Locusu,

jsem dlouholetým uživatelem aplikace Locus Map a při outdoorových aktivitách ji vždy používám. S tím, jak se funkce Locus Map 4 stále zdokonalují, jedna trápící zkušenost, která mě provází řadu let, stále nebyla vyřešena – když používám mapy Číny, poloha se vždy zobrazuje nesprávně. Doufám, že v nové verzi tento problém vyřešíte. Jedná se o vylepšení uživatelského komfortu pro konkrétní region. Někdy, pro větší pohodlí, musím použít i OruxMaps, protože dokáže dokonale vyřešit bolestivé body uživatelů v Číně. Pevně věřím, že i Locus Map 4 dosáhne toho, aby se poloha při používání map Číny nezobrazovala chybně.

Níže přikládám soubor providers.xmlz OruxMaps.

Hello tartiflix
I have been using https://arkluz.com/trk for almost a year now since I discovered it.
The overall feeling is still very good, but sometimes the network is not good.
I want to use your source code to build a website in China.
Could you please share this source code with me?
Thanks

I also used a real-time tracking system that supports both APRS and Locus Map customization here

If we could integrate the functions of the two platforms, the effect would be better

http://necc.co

Do you have a real-time tracking open source system?

Is there a source code download available

I like it so much

I want to see what teammates need to do in the Locus Map application

Hi! Hello friend

I really like your real-time trajectory project

How can I view teammates' positions in the local map app?
