1 Basic Map Info - 2 Orienteering in the terrain

2 An orienteering map is different from a topographic map: Mountaineers use a topographic map. The scale is usually 1 / 25 000 or 1 / 50 000 A topographic map shows: * only very distinct roads and vehicle tracks * only distinct rivers * forests - green * open areas - white

3 An orienteering map is more detailed: The scale is usually 1/10 000. * vegetation is more detailed: each colour has a meaning showing difference in vegetation * very small streams, even dried up water courses are shown * even small paths, tracks are shown

4 What can you see on a course map for orienteering? 1 - The scale 2 - The elevation (difference in height) between two contours --> contour interval 3 - The category this course belongs to 4 - The length of the course (as the crow flies) 5 - Control point definitions 6 - The course itself, shown by: * the start (triangle) * the finish (two concentric circles) * the control points (single circle)

5 THE SCALE The scale of the map is useful in estimating the distance from where you are now, and where you want to go. 1 / 10 000: 1 cm on the map = 100 meters on the terrain 1 / 5 000: 1 cm on the map = 50 meters on the terrain You need to know how to count your paces!

6 Pace counting Homework: Measure your pace for 100 meters * count 2 paces for 1 * count: - uphill - downhill - straight bit * count: - walking - jogging - running

7 Contour interval The contour interval shows the vertical difference in height (the elevation) between two contours. Contour interval = 5 m 5 m = One and a half stories in a block of flats The distance between two contours on the map will show the effort for climbing; Less effort Steep climb

8 Contour interval Homework: if the contour interval is 5 m Assuming the first contour lies at the lowest point (car park surface), how many contours for A? B? C? Which one has the most climb? Note: most climb may not mean longest distance! A B C

9 Yellow White Green show density of vegetation Blackshows man-made features or stone features rocks, stony ground, buildings, roads, paths, fences, special man-made objects... Blue shows water lakes, rivers, streams, dried up water course, well, fountain, swamp... Brown shows earth contours, knolls, pits, earth banks, special earth features... COLORS

10 Black Paved area Asphalt Road Fence Man-made object Power line Rockface (teeth point downwards) Building Rock Unpaved path

11 Man-made line features roads fences stone wall power lines

12 Difference in width...

13 Unpaved paths and tracks... Less distinct path, wide enough for only one person More distinct path, wide enough for 2 people to walk together Vehicle track wide enough for a vehicle to pass

14

15 asphalt road unpaved vehicle track distinct footpath less distinct footpath fence (passable) fence (impassable - forbidden to pass) ruined fence stone wall small power line or telephone line high voltage power line

16 Match the terrain with the map

25 Cultivated open land Rough open land Semi-open land with scattered trees Forest: easy running

26 Vegetation: difficult to run Vegetation: very difficult to run

28 Undergrowth or small shrubs may slow down your pace Dense forest runnable in one direction
