LESSON 12.17 SkillBuilder: Drawing a précis map
What is a précis map? A précis map is a simplified map — the cartographer has decided which details to leave in and which to leave out. It is different from a sketch map, which includes all the main features.
LESSON 12.18 SkillBuilder: Creating and reading pictographs
What is a pictograph? A pictograph is a graph drawn using pictures to represent numbers, instead of the bars or dots that are traditionally used on graphs. Data can be drawn vertically or horizontally. Each picture is given a value.
LESSON 12.19 SkillBuilder: Describing photographs
What is meant by ‘describing a photograph’? A description is a brief comment (up to a paragraph) on a photograph, identifying and communicating features from a geographic point of view. Sometimes it is necessary to infer information from a photograph; for example, a cloud of dust in an image may tell us that the climate is dry, or that the place is experiencing drought, or that some movement disturbed the soil at the time the photograph was taken.
LESSON 12.20 SkillBuilder: Constructing a basic sketch map
What is a basic sketch map? A basic sketch map is a map drawn from an aerial photograph or developed during fieldwork. It identifies the main features of an area and is different from a précis map, in which the cartographer opts to include or leave out certain features.
