[edit]Teaching geometry at a distance.
[edit]My granddaughter, 14, is about to start studying geometry in her school. They, of course, do everything remotely now. I am capable to assist her but I also think of possibly finding a program that could be employed on both hers and mine computer whereas I could draw pictures and also use stored figures for illustration. Does anybody know of something like this existing on the web? There are online courses, but is it what I need? We live at different states in the USA.

- Have a look at GeoGebra. --Wrongfilter (talk) 20:41, 3 January 2021 (UTC)
Why was the speed attribute removed in GPX 1.1?
[edit]The docs for gpxpy say that
- GPX 1.0 specified a speed attribute for every track point, but that was removed in GPX 1.1.
Why was it removed? It seems very useful. If you have a GPS receiver that reports speed using Doppler, that could be saved to the file, and could be used to do Kalman filtering (for example) on the data. --Trovatore (talk) 21:58, 3 January 2021 (UTC)
- Trovatore, the GPX developers' website has contact information. I would normally go first to the developer's forum, but that was a poorly-chosen Yahoo! Group, so it's been shut down. You can contact the website maintainer through this form. Elizium23 (talk) 22:08, 3 January 2021 (UTC)
