Cartographers and Photogrammetrists
Main Topic: Physical Geography
Secondary Topic: Cartography, G. I. Science
Overview: Cartographers and photogrammetrists gather, assess and interpret geographic information in order to create and update maps and charts for educational, research and official purposes. They use information from geodetic surveys and modern tools such as remote-sensing systems, LIDAR and satellite technologies to digitally map the topography of the Earth. The following are examples of Cartographers and photogrammetrists job titles:
Cartographers: Cartographers typically collect geographic data, create visual representations of collected data, examine and compile data from ground surveys, reports, aerial photographs and satellite images. They also prepare maps in digital or graphic form for environmental and educational purposes. They are also responsible for updating and revising changes in the existing maps and charts. They are mapmakers who design user-friendly maps.
Photogrammetrist: Photogrammetrists are responsible for planning aerial and satellite surveys to ensure complete coverage of the area in question. They also collect and analyze spatial data, such as elevation and distance as well as develop base maps that allow GIS data to be layered on top. They are specialized mapmakers who use various technologies to build models of the Earth’s surface and its features for the purpose of creating maps.
Cartographers and photogrammetrists often develop online and mobile maps. Interactive maps are popular, and collect data and design these maps for mobile phones and navigation systems. They also create maps and perform aerial surveys for governments, to aid in urban and regional planning. Such maps may include information on population density and demographic characteristics. Some of them help build maps for government agencies for work involving national security and public safety.
