Collects, analyzes and interprets geographic information provided by geodetic surveys, aerial photographs, and satellite data. Researches, studies and prepares maps and other spatial data in digital or graphic form for legal, social, political, educational, and design purposes. May work with Geographic Information Systems (GIS). May design and evaluate algorithms, data structures, and user interfaces for GIS and mapping systems.
This career is part of the Agriculture, Food and Natural Resources cluster Natural Resources pathway.
