How about a GPS Cops and Robbers type game? Uses a GPS web app and played over a wide area with multiple teams. Players can set up their own games anywhere in the world.

For the moment I managed to done some operation with gpsbabel and its filtering option.(see GpsBabel Manual). I do not have the visualization of the tracks, but manage to do the merge, and trim (and you can automatize the work using scripts instead of editing each file individually) I am still looking for a tool with visual feedback.

Your units are in decimal degrees and they should be in a projected coordinate system. If you still have the gps unit, you can change it to something like an appropriate UTM projection then download the coordinates and use those in your calculation.

I upvoted @user27285's answer. I don't know any better. I use the Josm editor with the EditGPx Plugin and other JOSM features to edit my gpx traces all the time. You can configure Josm to show when your track changed directions by color styles. On top of all those features you also have reference Imagery layers to pick from to help see where your data is ...

I'm also searching for a really good way to do this... but in the meantime I do have a system which works OK. Slow but effective: Use the Openstreetmap editor JOSM. This is good at displaying GPX info. Use the plugin 'InfoMode'. This makes it easy to see the time data on the GPX track. Note exact times for the nodes which you want to edit/delete etc. Edit ...

Spatialite-gui has a tool "Import EXIF photos" for that. The current Spatialite version is 4.2 but this old document is still valid https://www.gaia-gis.it/spatialite-2.3.1/spatialite-exif-2.3.1.html. You can also easily export the data from Spatialite into other formats like txt/csv or dbf with another tool in Spatialite-gui.

On the ArcGIS stack, there is the Geotagged Photos to Points tool. Reading the EXIF GPS fix is a fairly easy thing to do, it should be possible in Python using something like using PIL (sample) and xlwt (sample).

If you set the project CRS in QGIS to EPSG:32718 (UTM zone 18), you get the same coordinates as reported by Google Earth. You might get different results if you have chosen another CRS. There are several CRS that are called UTM 18S (=South), but only one is based on the WGS84 ellipsoid. The negative Y coordinate looks like a UTM 18N (=North) CRS. For QGIS, ...

First of all, the GPS Almanac consists of information about the GPS constellation, satellites' health and their course in order to make it easier (possible) for your receiver to find them in the air. (Most of the time, you do not need to download that since you did before, but that is a discussion for another Q/A). The point is, almanac is not important for ...

You should be able to do a simple 'select by expression' where DATECOLUMN like "% 12%" This is assuming your date is a string column. Essentially; the query is using the 'pattern' that is formed, and saying "Find me every record where there's a space, followed by 12, follow by a colon. Since your data is in 24h format, the only records criteria that ...
