How to be a cartographer

In February, 2014 Siddharth Hande, an environmental activist held a workshop for IIT students that had them sit up and listen to with interest. During the time allotted to him Hande was their Social Scientist Guide to map and map-making. A geo-spatial analyst and researcher in Urban Studies and New Media, Hande promotes citizen cartography – people making maps of their immediate neighbourhoods. He believes maps are not impartial reference objects (not merely physical/political/polar), but “instruments of communication, persuasion, and power.” Like paintings, they express a point of view, by connecting us to a world of property lines, voting rights and enterprise zones, they embody and project the interests of their creators [Dennis Wood, The Power of Maps]. Participants carried home guidelines to survey methods using GPS and paper-mapping, analysis and visualization with QGIS and web-mapping – how to publish maps online and tips on using Google maps.

Can one make a career in cartography? Yes, says Professor Jagannathan, HOD, Geography, Madras University. “Students have to learn cartographic grammar and do laboratory work to get high-level skills in digital-mapping including web maps.” Basic qualifications needed are excellent computer/mathematical/design skills, spatial awareness, ability to analyse information from different sources, logical approach, a high level of accuracy and attention to detail. Hands-on experience is necessary and most successful modern-day cartographers are at least partially self-taught.

As for academic qualifications, you could get a B.Sc Geography, M.Sc Geography, M.Sc Applied Geography, M.Sc Spatial Information Technology, M.Sc Cartography, M.Sc Geographic Information System, M.Sc Remote Sensing, M.Sc Geoinformatics, M.Tech Geoinformatics, P.G.Diploma in GIS, Cartography, Surveying and mapping/topographic/earth sciences or urban and land studies before applying for jobs.

“Cartography is an interesting career because it is a true blend of art, science, and technology,” says the Professor. “Making professional-quality maps requires strong education in geography with a focus on cartography and remote sensing, mathematics through basic calculus and statistics, introductory computer science including programming and database management, and basic graphic design.” With a UG degree, you could serve as a Junior Cartographer, mapping assistant or a GIS/Cartographic assistant. Excellent opportunities in government/NGO/International institutions await those with a PG. After completing PhD, you can apply for top-level jobs like Geomatics consultant, research fellow, post-doctoral fellow, GIS analyst/co-ordinator, mapping scientist/Professors/ Technical Support Analyst and a host of similar positions like GIS sales manager, Internet Product Software Engineer and Applications Programmer.

Go for it, says the professor. Mapping business could grow by 30% annually, geoinformatics is a growing field and a special type of IT. It will solve all spatial problems – from those of villages to those of the highest level of policy-makers, of NGOs, industries, higher education. It is a field that employs advanced digital technology tools like QGIS, Inkscape, GIMP, Scribus, colorbrewer. These save time and gift you with beautiful, well-composed maps. Cutting-edge digital technology is used in Geographical Information Systems, web mapping technology, spatial database, photogrammetry, remote-sensing, GPS, geo-spatial intelligence.

As a cartographer you will make maps for the military, industries, special territories (tribal land) as well as everyday maps detailing roads and footpaths for tourists/travellers. Cartographers collect, analyze, and interpret both spatial (latitude, longitude, elevation, distance) and non-spatial data (population density, land-use patterns, annual precipitation levels, demographic characteristics). Maps are prepared either in graphic or digital form with information from satellites, light-imaging detection and ranging (LIDAR), aerial cameras, geodetic surveys and remote sensing systems. Remuneration depends on qualifications and who you work for - a qualified person can expect a starting salary of around Rs. 10,000 - 15,000 per month. Overseas organization are known to pay around Rs.500,000-Rs.1,000,000 per year. With experience of two years, one can earn Rs.50,000 per month or more.
