I record my hikes using a GNSS receiver. Recorded tracks are available to download below as GPX files. Each .gpx file is paired with a statistics (stats.txt) file and comes packaged in a .zip file. I use Simple GPX to remove timestamps and simplify tracks to 20 m (66 ft) accuracy.

I also contribute these files to OpenStreetMap (OSM). Public GPX files uploaded to OSM are available on the Public GPS Traces page. Learn more about recording GPS tracks.

I’m Gerhard Lanz—a spatial professional with a creative streak. I believe in a world enriched by location information.

I have been working with Geographic Information Systems (GIS) as a Geospatial Analyst since 2012. If I’m not sitting in a room lit only by glow of raster data, you can probably find me in the great outdoors.

This website is intentionally simple—it allows me to focus on what really matters. It is also GDPR complaint. This website does not use any tracking scripts, nor does it collect, use, or share any personal data.
