Overview

The trips dataset records the GPS locations where faecal sludge trucks collected sludge in Kampala, Uganda, between 30th March 2015 and 25th June 2015. Each record is tagged with the treatment plant the truck was associated with (Bugolobi or Lubigi).

The README shows these locations as a static image, because GitHub does not render JavaScript widgets in Markdown. This article renders the map as a fully interactive leaflet widget that you can pan, zoom, and click. The colour of each circle marker indicates the associated treatment plant, and the two larger markers show the location of each plant.
