cartographer (geography)

A cartographer is involved with the scientific, technological and artistic aspects of developing and producing maps. Cartographers present complex information as diagrams, charts and spreadsheets, as well as in the form of conventional maps. Geographical information systems (GIS) and digital-mapping techniques now dominate the role.
Maps and detailed geographical information are needed for a range of purposes, from everyday use by individuals to large-scale industrial development.
Cartographers work within a variety of areas, including publishing, government, surveying and conservation. The role varies widely from the development and design of geographical information to more strategic and technical work.

Typical work activities

The traditional methods employed in map-making have been superseded by the use of IT, enabling the generation and manipulation of dynamic images on screen. These developments have led to changes in the nature of the profession: within map-making, almost all the data is now collected and transmitted electronically, whereas in cartographic illustration the change has been less marked. In commercial cartographic publishing, the work has more in common with book publishing, requiring innovative design skills.
A cartographer's role can vary widely; from the technical role of the development, maintenance and manipulation of cartographic databases to the promotion of effective and efficient visualisation of geospatial information, to the design of bespoke maps.
Typical work activities may include:
  • designing maps, graphics, illustrations and layouts;
  • communicating information through the use of colour, symbols, style and other means;
  • using computers to compile and produce graphs for specialist and general users;
  • researching, selecting and evaluating map source data for use in the preparation or revision of maps and charts to various scales;
  • analysing and evaluating mappable information;
  • liaising with surveyors and designers;
  • collating data provided by remote sensing techniques (the means by which spatial and environmental data about the earth are acquired by sensors located in satellites and aircraft);
  • operating a photogrammetric plotting instrument or a digital photogrammetric workstation (DPW), which views the photographs stereoscopically, or in a 3D format;
  • design, maintenance and manipulation of geographical information (GI) databases;
  • working with geographical information systems (GIS) to see, model and analyse landscape features;
  • using desktop publishing packages to edit and formulate information;
  • capturing, maintaining and outputting digital geographic data;
  • generalising map data to allow for a reduction in scale (derived mapping);
  • checking and appraising the content and accuracy of maps, charts and printing proofs;
  • keeping up to date with emerging specialist software;
  • as seniority increases, managing projects, staff and resources
  • Range of typical starting salaries: £15,000 - £18,000.
  • Range of salaries with three to five years' experience: £20,000 - £25,000.
  • Range of typical salaries at senior levels: £30,000 - £45,000.
  • Salaries and conditions vary between employers and between the public and private sectors.
  • Working hours are mainly nine to five, usually based in an office, at a workstation. Flexi-time is common. While many of the more junior roles in cartography are information or desk-based, at senior levels there may be more interaction with other departments or clients.
  • The level of pressure varies according to role, though it is likely to rise when meeting publication or project completion deadlines.
  • Short-term contracts are increasingly common in the private sector.
  • Consultancy work is possible with considerable experience. Academic opportunities are scarce.
  • A small number of cartographers with experience go on to run their own companies or work on a self-employed basis.
  • Jobs are mainly available in south and southeast England, for example, in government departments, especially those involved in cartographical publishing.
  • Geographical mobility, in order to move laterally across the job market, may be necessary in your early career.
  • Travel within the working day is sometimes needed, but overnight absences and overseas travel are uncommon.
