I could have also said: “All the places I went last year”, but it would not be that accurate. Instead of yuxtaposing the raw gpx tracks, I found that giving them a transparency they would tell the story better. The black spot is the consequence of not turning on the GPS in closed spaces (noise).
- Record every movement you make with a GPS.
- Download all the .gpx files from your GPS.
- Merge all your recorded tracks (.gpx files) with Merge tool (Windows).
Run the program inside the folder and it will merge all the gpx files in one.
- Open the generated .gpx file into JOSM. Convert the layer to a data layer (right click button) and you’ll be able to edit the points. Save the layer as another (clean) .gpx file.
- Open Qgis and import the gpx from last step (seen in cartotalk).
- Create a new layout, insert the map and export to pdf or svg.
- Open it in inkscape (or illustrator, or freehand) and put the lines with transparency 25%.
- If your computer is ‘strong’ enough you’ll be able to export/print the resulting image (I had some problems with it).
Note: It might be a little bit to intimate to show all this traces, but it looked so nice that I had to post it. Years ago I did a similar map drawing with a pilot every movement I made on a Madrid touristic paper map. I never published it. Different tools, same story.
