Career Description

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.

What Job Titles Cartographers and Photogrammetrists Might Have

• Cartographer
• Compiler
• Photogrammetric Technician
• Photogrammetrist

What Cartographers and Photogrammetrists Do

• Determine map content and layout, as well as production specifications such as scale, size, projection, and colors, and direct production to ensure that specifications are followed.
• Inspect final compositions to ensure completeness and accuracy.
• 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.
• Prepare and alter trace maps, charts, tables, detailed drawings, and three-dimensional optical models of terrain using stereoscopic plotting and computer graphics equipment.
• 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.
• Examine and analyze data from ground surveys, reports, aerial photographs, and satellite images to prepare topographic maps, aerial-photograph mosaics, and related charts.
• Identify, scale, and orient geodetic points, elevations, and other planimetric or topographic features, applying standard mathematical formulas.
• Determine guidelines that specify which source material is acceptable for use.
• Collect information about specific features of the Earth, using aerial photography and other digital remote sensing techniques.
• Study legal records to establish boundaries of local, national, and international properties.
• Select aerial photographic and remote sensing techniques and plotting equipment needed to meet required standards of accuracy.

What Cartographers and Photogrammetrists Should Be Good At

• Oral Comprehension - The ability to listen to and understand information and ideas presented through spoken words and sentences.
• Near Vision - The ability to see details at close range (within a few feet of the observer).
• Written Comprehension - The ability to read and understand information and ideas presented in writing.
• Oral Expression - The ability to communicate information and ideas in speaking so others will understand.
• Written Expression - The ability to communicate information and ideas in writing so others will understand.
