Junior Photogrammetrist

Leidos•St. Louis, MO

21h•$59,150 - $106,925

About The Position

The Junior Photogrammetrist provides photogrammetry support to a customer, including support related to LiDAR processing and analysis or generating point clouds from EO imagery, and co-registering multi-source datasets. The role assists with producing, reviewing, and validating elevation DEM products and uses SOCET GXP and other geospatial software to generate, edit, quality-control, and finish DEMs and orthorectified imagery. The position also performs stereo-imagery feasibility analysis and collaborates in meetings to maintain clear communication. The role requires an active TS/SCI clearance, a high school diploma, and 2–3 years of relevant experience. CONUS travel may be required for one-week trips to geographically separated branch locations, up to four times per year. Shift work may be required due to production workstation limitations in STL.

Requirements

Basic experience with stereoscopic viewing and editing using electronic light tables, such as SOCET GXP.
Basic knowledge of photogrammetry, data processing and analysis, and DEM generation.
Basic understanding of processing and analyzing elevation data or 3D point clouds, and documenting precision and error in accordance with existing data standards.
Basic understanding of co-registering multiple datasets to the WGS 84 reference frame and performing statistical analysis to determine absolute and relative error.
Basic experience using SOCET GXP, QTModeler, or similar elevation or point-cloud processing and analysis software.
Knowledge of digital data formats such as vector data, raster data, or shapefiles.
Strong oral and written communication skills.
Active TS/SCI clearance.
High school diploma and 2–3 years of relevant experience.
