Because LIDAR is often more accurate than traditional surveying methods, it can also be used to collect other forms of data, such as the location and density of forests.Ĭartographers and photogrammetrists often develop online and mobile maps. LIDAR systems use lasers attached to planes or cars to digitally map the topography of the Earth. Some also use light-imaging detection and ranging (LIDAR) technology. Photogrammetrists are specialized mapmakers who use various technologies to build models of the Earth’s surface and its features for the purpose of creating maps.Ĭartographers and photogrammetrists use information from geodetic surveys (land surveys that account for the curvature of the Earth’s surface) and remote-sensing systems, including aerial cameras and satellites.

How to Become a Cartographer or PhotogrammetristĬartographers and photogrammetrists typically need a bachelor’s degree in cartography, geography, geomatics, or surveying. Work EnvironmentĪlthough cartographers and photogrammetrists spend much of their time in offices, certain jobs require extensive travel to locations that are being mapped. What Cartographers and Photogrammetrists DoĬartographers and photogrammetrists collect, measure, and interpret geographic information in order to create and update maps and charts for regional planning, education, and other purposes.
