GS-1311 - Physical Science Technician Series
This series includes positions that involve nonprofessional technical work in the physical sciences and that are not specifically included in other series in the Physical Sciences Group. Positions in this series require a knowledge of the principles and techniques of physical science, but do not require competence equivalent to that represented by the completion of a full four-year college curriculum leading to a bachelor's degree in physical science. Positions in this series involve work in the fields of astronomy, chemistry, geology, geophysics, health physics, hydrology, metallurgy, oceanography, physics, and other physical sciences.
This series includes all positions involving work that requires full professional education and training in the field of chemistry. This work includes the investigation, analysis, and interpretation of the composition, molecular structure, and properties of substances, the transformations that they undergo, and the amounts of matter and energy included in these transformations. This work includes the investigation, analysis, and interpretation of the composition, physical and chemical properties, molecular structure and chemical reactions of substances; the prediction of transformation that they undergo; and the amount of matter and energy included in these transformations.
This series includes positions requiring the application of professional knowledge and skills in mapping and related sciences, and relevant mathematics and statistics to plan, design, research, develop, construct, evaluate and modify mapping and charting systems, products, and technology.
GS-1371 - Cartographic Technician Series
This series includes positions that require primarily a practical knowledge of the processes, practices, methods, and techniques involved in the construction of new or revision of existing maps, charts, and related cartographic products. Cartographic aids and technicians perform precompilation tasks (such as the investigation of source materials, the extension of basic geodetic control network, and the plotting of map projection and ground control on base sheets), manual or photogrammetric compilation, assembling aerial photographs into mosaics, drafting, digitizing, and editing or reviewing. The positions do not require full professional knowledge and abilities and, therefore, do not require education equivalent in type and scope to that represented by completion of a professional curriculum leading to a bachelor's degree in cartography or a related science.
This series includes positions that involve professional work in land surveying that is concerned with establishing, investigating, and reestablishing land and property boundaries, and with preparing plats and legal descriptions for tracts of land. The work requires application of professional knowledge of the concepts, principles and techniques of surveying, including underlying mathematics and physical science, in combination with a practical knowledge of land ownership laws.
