Collect, analyze, and interpret geographic information provided by geodetic surveys, aerial photographs, and satellite data. Research, study, and prepare 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.

Select aerial photographic and remote sensing techniques and plotting equipment needed to meet required standards of accuracy. Delineate aerial photographic detail, such as control points, hydrography, topography, and cultural features, using precision stereoplotting apparatus or drafting instruments. Build and update digital databases. Prepare and alter trace maps, charts, tables, detailed drawings, and three-dimensional optical models of terrain, using stereoscopic plotting and computer graphics equipment. Determine guidelines that specify which source material is acceptable for use. Study legal records in order to establish boundaries of local, national, and international properties. Travel over photographed areas in order to observe, identify, record, and verify all relevant features. Identify, scale, and orient geodetic points, elevations, and other planimetric or topographic features, applying standard mathematical formulas. Collect information about specific features of the Earth, using aerial photography and other digital remote sensing techniques. Revise existing maps and charts, making all necessary corrections and adjustments. Compile data required for map preparation, including aerial photographs, survey notes, records, reports, and original maps. Inspect final compositions in order to ensure completeness and accuracy. Determine map content and layout, as well as production specifications such as scale, size, projection, and colors, and direct production in order to ensure that specifications are followed. Examine and analyze data from ground surveys, reports, aerial photographs, and satellite images in order to prepare topographic maps, aerial-photograph mosaics, and related charts.
