What the work is
Research, study, and prepare maps and other spatial data in digital or graphic form for one or more purposes, such as 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. May collect, analyze, and interpret geographic information provided by geodetic surveys, aerial photographs, and satellite data.
On a typical day
- 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 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 to ensure that specifications are followed.
