Google Maps Routes to Dawarich

[zku]

I wanted to add my routes from an old trip (from before Dawarich) at least retroactively. Since it might also be interesting for others, I wanted to briefly describe the workflow via Grasshopper and QGIS. There are probably other (maybe easier?) ways, but for me this was the simplest.

1. Reconstruct the routes in Grasshopper ( GraphHopper Maps | Route Planner ) and export them as GPX

2. Load the GPX into QGIS and export it as GeoJSON (right-click on layer → export)

3. Add timestamps to the points:

Select the layer and switch to edit mode (1 pen symbol)
Open the field calculator (2 calc symbol)
Replace an existing field → select time

Then add a time value like this (e.g., every 10 seconds starting from 20.08.25):

to_datetime('2025-08-20 12:00:00')
+ make_interval(0,0,0,0,0,0, $id * 10)

Safe the changes (click again 1)

…and import the GeoJSON into Dawarich!
