What are topographical plans and maps?
1. Topographical plans and maps are drawings which show the main physical features on the ground, such as buildings, fences, roads, rivers, lakes and forests, as well as the changes in elevation between land forms such as valleys and hills (called vertical relief). You base these plans and maps on the information you collect from topographical surveys.
2. Plans are usually large-scale drawings; maps are usually small-scale drawings. Depending on the scale you use to make the drawing (see Section 9.1):
it is a plan if the scale is larger than 1 cm for 100 m (1 : 10 000), for example 1 cm for 25 m;
it is a map if the scale is equal to or smaller than 1 cm for 100 m (1 : 10 000), for example 1 cm for 200 m or 1 cm for 1000 m.
