‘How geographers work’ examines the methods employed by geographers. Geographers need to employ a wide range of skills. Fieldwork is a key activity, which developed from the expeditions undertaken by pioneers. This is used in both physical geography, when gathering data or testing hypotheses, and in human geography, when conducting questionnaires. Maps are synonymous with physical geography, but human geographers study mental maps held by local people. Numeracy has been essential since the quantitative and information revolutions. Geographers must also be literate in a wide range of academic fields. Applied geography proclaims the importance of geography to the real world, and is evidenced by geographers' participation in policy discourse.
