Overview

Creak track lines between GPS points based on the animal and date/time.

Points to Path

  1. Search for Points to Path in the processing tool box. This will create lines between sequential points. Since there are multiple unique animals, you'll want to group by the unique tag_ident and order by the timestamp field.

  1. Without changing the path, it's going to save it as a memory layer (or 'scratch' layer). As it's in memory, it's not written off to disk and will vanish once you close QGIS. Incase our QGIS crashes let's save it as a shapefile file by selecting the three dots next to path.

  2. Click Run.Your map should look like the below:

  1. Now we can style the lines based on the individual. Right click the layer > Properties > Symbology

  2. Change the top drop down option to Categorized and select the value tag-ident

  3. Select a color ramp of preference

  4. At the bottom of the window screen, select Classify > Apply

Your map should look something like this:
