Coordinate findings with the work of engineering and architectural personnel, clients, and others concerned with projects. Adjust surveying instruments in order to maintain their accuracy. Establish fixed points for use in making maps, using geodetic and engineering instruments. Determine longitudes and latitudes of important features and boundaries in survey areas, using theodolites, transits, levels, and satellite-based global positioning systems (GPS). Train assistants and helpers, and direct their work in such activities as performing surveys or drafting maps. Analyze survey objectives and specifications in order to prepare survey proposals or to direct others in survey proposal preparation. Compute geodetic measurements and interpret survey data in order to determine positions, shapes, and elevations of geomorphic and topographic features. Develop criteria for survey methods and procedures. Develop criteria for the design and modification of survey instruments. Conduct research in surveying and mapping methods, using knowledge of techniques of photogrammetric map compilation and electronic data processing.
