Understanding vegetation mapping


Orienteers should understand a few things about the way vegetation is mapped:

  • The darker green an area is on the map the thicker the vegetation / forest is in the terrain
  • Forest mapping represents both the runnability and the visibility. Areas of low vegetation where the runnability is reduced but hte visibility is generally still high are marked with thin green stripes.
  • Edges of vegetation symbols are typically indistinct in the terrain. Distinct edges are marked with the distinct vegetation boundary symbol (block dots or short dark green dashes). Orienteers should be able to identify these boundaries in the terrain as well as on the map.
