Cartographer

Cartographer are mapmakers. They gather, evaluate, and visualize geographic information and analyze geographical data to create charts and reports. They combine creativity with technical aptitude to produce, for example, topological maps, aeronautical charts, natural resource maps, or nautical charts and other hydrographic maps. In addition, they may work on demographic maps such as population characteristics, economic maps such as land use, or social maps such as crime rates and poverty.

At a Glance

Imagine you are sitting in a quiet, brightly lit room with a huge drawing table, a couple of big computer screens, and stacks of maps and photos. You stare intently at a series of photos of a river in the northern part of the province. Last month, heavy storms caused the river to flood its banks. When the water receded, the river had noticeably changed course. As a cartographer, you will update old maps of the area, redrawing the river's new course. This river is an important part of a large watershed, so accurate maps are critical to local watershed managers and land-use planners. You start by comparing aerial photos and old maps to get a sense of where the river has moved and how much it has changed.

In the weeks since the river receded, teams of surveyors have been taking measurements and re-surveying the river's course. You will use their data, as well as data from geological surveys and elevation maps, to construct your map. You use sophisticated cartography software to redraw the maps. But the software isn't a perfect substitute for a pencil and a ruler and can't replace your technical and artistic skills. Once you have your computer-generated map, you will continue to revise it to make it as accurate as possible. Finally, you'll add the legend and scale, and the updated map will be ready for use.
