Engineering-Related Tech

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.

• Compile data required for map preparation, including aerial photographs, survey notes, records, reports, and original maps.
• Delineate aerial photographic detail, such as control points, hydrography, topography, and cultural features, using precision stereoplotting apparatus or drafting instruments.
• Prepare and alter trace maps, charts, tables, detailed drawings, and three-dimensional optical models of terrain using stereoscopic plotting and computer graphics equipment.

Make exact measurements and determine property boundaries. Provide data relevant to the shape, contour, gravitation, location, elevation, or dimension of land or land features on or near the earth's surface for engineering, mapmaking, mining, land evaluation, construction, and other purposes.

• Direct or conduct surveys to establish legal boundaries for properties, based on legal deeds and titles.
• Prepare and maintain sketches, maps, reports, and legal descriptions of surveys to describe, certify, and assume liability for work performed.
• Write descriptions of property boundary surveys for use in deeds, leases, or other legal documents.

Apply theory and principles of mechanical engineering to modify, develop, test, or adjust machinery and equipment under direction of engineering staff or physical scientists.

• Assemble or disassemble complex mechanical systems.
• Interpret engineering sketches, specifications, or drawings.
• Calculate required capacities for equipment of proposed system to obtain specified performance and submit data to engineering personnel for approval.

Perform surveying and mapping duties, usually under the direction of an engineer, surveyor, cartographer, or photogrammetrist, to obtain data used for construction, mapmaking, boundary location, mining, or other purposes. May calculate mapmaking information and create maps from source data, such as surveying notes, aerial photography, satellite data, or other maps to show topographical features, political boundaries, and other features. May verify accuracy and completeness of maps.

• Position and hold the vertical rods, or targets, that theodolite operators use for sighting to measure angles, distances, and elevations.
• Check all layers of maps to ensure accuracy, identifying and marking errors and making corrections.
• Design or develop information databases that include geographic or topographic data.
