garmin-opentopo VS GarminDB

For my purposes I wanted an extremely stripped down style file. You can see other examples of styles here: https://github.com/8cH9azbsFifZ/garmin-opentopo/tree/master/lib/fzk-mde-garmin-develop/Freizeitkarte-Entwicklung/style (in the example above you would have a folder called your_style instead of fzk). I'm not sure how the file naming works, but for my purposes I have a info, lines, options, points, polygons, and relations file (no file extensions). The points and relations files are completely blank, since I don't care about routing or landmarks. My style will render easy runs green (line type 0x01) intermediate as blue (line type 0x02), etc. Anything that is a night run will have a yellow line rendered behind it, and the chair lifts are rendered in red. Look at the TYP file to see how I made 0x01 a green line.

How are you syncing/storing the data?

I've been a Garmin user for nearly a decade and would really like to get the data off their platform so I can do more with it.

There are a few self-hosted options (https://github.com/tcgoetz/GarminDB seems like the best) but I keep kicking that can down the road.

You may want to check out https://github.com/tcgoetz/GarminDB if you're using a newer (Elevate v4 or v5 sensor) Garmin device.

https://graphhopper.com/maps/ is an amazing product that is open source, but it just does routing (with GPX download). I wish it had a little PostGIS data browser that I could write into via routes I draw on the map, or I upload (or import from other devices using something like GarminDB or similar). That, and adding arbitrary points, would be great. Just a simple, general-purpose map authoring tool. I just feel like I'm missing something, it seems like this would exist already.

If you are just interested in getting the data, GarminDB works really well.

Have a look at GarminDB. It allows you to download all your activity files.

I found this https://github.com/tcgoetz/GarminDB, it looks like the thing you're talking about. However it doesn't use "the" API or a API: It web-scrapes the data from your "Daily Summary" page on Garmin Connect. It can also import data that has been exported (manually) from Garmin Connect. Neither of these two are an API.

Ah, sorry I thought I had linked GarminDB in my post. It's a set of python scripts for downloading fitness and health data from Garmin Connect or a Garmin device via USB and importing into a SQLite database. The idea is then to visualize/analyze the data with something like Jupyter.

This tool is for Peloton -> Garmin. I personally haven't tried to export Garmin -> X myself as I haven't had the need yet, but there seems to be a few repos where I'd start looking: * https://github.com/petergardfjall/garminexport * https://github.com/tcgoetz/GarminDB
