CCHARACTERISTICS OF A MAP

MAP SCALE

The scale of a map is defined as the quotient of the horizontal distance between two points on the map and the same two points on the ground.

The larger the denominator, the smaller the scale. For example, maps at a scale of 1:25 000 are detailed whereas those at 1:250 000 are small scale maps.

RANGE OF SCALES			DENOMINATION SCALE / MAP			BASE MAP UNIT
Less than 1:500 000			Very small / exploratory			> 625 ha
100 000 - 500 000			Small / survey			25 - 625 ha
25 000 - 100 000			Medium / semi-detailed			1,5 - 25 ha
10 000 - 25 000			Large / detailed			2 500 - 15 625 m2
Greater than 10 000			Very large / intensive			< 2 500 m2

The larger the scale of a map, the smaller the spatial variability of the map units represented (greater degree of purity): large scale maps are therefore more interesting for making predictions and appropriately assigning land uses.
