Adding features based on a GPS route

A smartphone, like any GPS tracker, can record journeys. The journeys can be used as the basis for adding features to the map.

In this example, I used the Runkeeper app to track a walk. (Any of Runkeeper’s competitor apps would work just as well.) Afterwards, I downloaded the tracked journey as a GPX file, and imported it into Open Orienteering Mapper.

Runkeeper trace of a route

I walked along the centre of clear paths in the mapped area. The journey mostly coincides with mapped trails, except for the south-western bit.

To turn that part of the path into a map feature, I clip the path at its junctions with the existing mapped trails, and delete the overlapping parts.

I adjust the endpoints of the remaining portion to form neat junctions with the adjoining trails, then use the switch symbols tool to turn the imported path into a less distinct trail symbol.

The imported route is now a mapped object

This technique works well for mapping linear features.

This article is part of the Orienteering Mapping with LiDAR, Smartphones and Free Tools series.

Polite and constructive responses are always welcome.

Hopeless at orienteering, rubbish at flying radio controlled planes, but enjoys both activities anyway.
