Job description

The Nevada Department of Transportation (NDOT) is recruiting for a Photogrammetrist/Cartographer 2 position in Carson City, NV. Incumbent will perform Photogrammetirc Compilation by collecting both planametric features as well as 3D DTM data. This will be achieved by measuring with 3D images through stereo monitors. ***Applicants must be authorized to work for ANY employer in the U.S, we are unable to sponsor or take over sponsorship of an employment Visa at this time. Please note that this position is on-site and does not offer remote work options. The Job Duties section listed in this announcement reflects the Statewide Class Specifications for all positions and do not fully correlate with the specific duties of this position***.

Photogrammetrist/Cartographers perform remote sensing work in the preparation of contour maps, terrain models, profile sheets; digital animated fly-through and related mapping materials which require the application of photogrammetric or cartographic techniques. They then apply photogrammetric or cartographic principles in the production and distribution of topographic maps, orthophotographs, planimetric maps and related products requiring the application of those techniques and principles. Work involves the scanning and analysis of aerial photographs and survey data applying standard mathematical formulas and mapping techniques to identify, scale, and orient geodetic survey control, elevations, and other planimetric or topographic features with associated cartographic detail in creating and preparing original maps, charts, and drawings. Work products must graphically delineate details such as survey control points, hydrography, topography, and cultural features using digital workstations, specialized software, precision plotting apparatus, and other technical equipment. Incumbents re-project, create, revise and merge existing elevation models, orthophotographs, and mapping from disparate sources using specialized software. Transformation of map and photo data is performed utilizing a working knowledge of various coordinate systems. Bachelor's degree from an accredited college or university in photogrammetry, cartography, physical science, geography, civil engineering, or related field and one year of photogrammetric and/or cartographic experience which included compiling digital map files from aerial photography and survey data; operating manual and computerized photogrammetric or cartographic equipment; OR an Associate's degree from an accredited college or university in photogrammetry, cartography, physical science, geography, mapping, surveying, civil engineering or related field and two years of progressively responsible experience as described above; OR one year of experience as a Photogrammetrist/Cartographer I in Nevada State service; OR an equivalent combination of education and experience. Prepare photo flight requests for mapping projects; identify areas to be mapped showing area to be covered, altitude and flight path for low and high altitude photo flights; and select and use field Global Positioning System (GPS) points for control of mapping data, Geographic Information System (GIS) datasets and attributes using resource grade GPS collection units.

Create scalable plots and 3D digital animation fly-through products utilizing data from orthophotos, LiDAR point clouds, terrain models and other remote sensing data. Operate metric aerial camera system and maintain current camera calibration.

Analyze flight photos to determine specific overlap and quality, and perform aerial triangulations by analytic, semi-analytic or digital methods.

Perform map compilations based on horizontal and vertical positions which are compared to completed field survey files; prepare topographical maps, cross sections, profiles, and renderings through digital map compilations; review final mapping files for accuracy of contour intervals, elevations, grid coordinates, and planimetric features; calculate map accuracy, create statistical reports, and ensure agency standards are met using the National Standards for Spatial Data Accuracy method (NSSDA).

Consult with other divisions and outside entities to determine required mapping needs while exceeding minimum required standard mapping specification.

Collect and maintain GIS datasets. Generate map compilations and create computer-aided design drafting (CADD) files in compliance with agency standards; convert existing mapping (rotate, scale and transform), create, re-project and incorporate existing graphical Public Land Survey System (PLSS) and administrative boundary data into design files, and establish mapping parameters for other divisions within the agency or outside contractors.

Maintain and calibrate equipment to ensure proper and accurate operation; maintain equipment inventory, repair, and maintenance records.

Provide training to lower level staff regarding digital mapping programs, accuracy, and mapping procedures.

Perform related duties as assigned.

Under general supervision, incumbents perform the full range of duties in the series concept. Incumbents will be responsible for specific work duties unique to the assigned section. These specific duty sections include: Cartography, Imagery and Photogrammetry.
