Oh, mapmaker, mapmaker, make me a map—the need for people who gather and interpret geographic information to make maps will bloom by 30 percent by 2024. The much-faster-than-average growth is driven by the need for maps in everything from managing government lands to the ever-growing number of mobile and web-based mapping tools, says BLS’s Emily Richards. Photogrammetry (from photo meaning “light,” gram meaning “drawing,” and metry meaning “measurement”) is the science of taking measurements from photos—think aerial photos taken from a plane or satellite—and then creating maps or 3D models. Cartographers and photogrammetrists make good money: a median annual salary of $60,930 (as of May 2014). And they’re in high demand in some highly desirable areas: Denver, Colorado; Portland, Oregon; Washington, D.C.; and Anaheim, California.
