C.S
Relief
refers to the highest and lowest elevation points in an area.
Spot heights
- exact height of a place on a map in meters above sea level
- usually written in black.
Triangulation Pillars
- Triangulation pillars also show height
- usually at a high spot on the land
- drawn as a dot inside a blue triangle on the map
Layer Shading
- shown in different colours
- need a key
- layer contouring can tell you a good deal about the shape of the land.
Contour Lines
- a line on a map joining points
- equal height above or below sea level.

How to measure the distance:
Using a scale line
Straight line distances:
To measure using the straight-line method. Measure from the starting point to the finishing point. Once you do that you need to put it on a scale line and get the distance
Curved distances:
With curved distances, you need to measure point by point. (A-B, B-C, C-D.eg). After that is done, you once again measure it on the scale line to get the distance.
(Contour lines)
The higher the number the…
