I have a Leaflet page, that fetches various GPS tracks and data from a website and filters the resulting GeoJSON files via HTTP GET variables.
If you want to get the data just for one day, I can use this URL:
I need to view some data now as well in QGIS. I can add the layers fine, but when I want to change the date, I have to manually edit the date in every layer.
Is there any possibility to have a textbox, where I can add the date and it will be applied to all GeoJSON layers.
I have looked at the filtering, but if I export all tracker points, it takes ages to load the data.
