LiDAR Hydrology Technician
Portland, OR, USA
Description: Quantum Spatial is seeking a LiDAR Hydrography Technician. The position will focus on the development of new hydrography delineations in Oregon and Washington, using high quality LiDAR-derived Digital Elevation Models (DEMs), imagery, and field collected data, which will be incorporated into the high-resolution National Hydrography Dataset (NHD) and National Watershed Boundary Dataset (WBD). The selected candidate will also perform editing of vector hydrography data and update the NHD to incorporate the LiDAR-based delineations.
Hydro-enforce DEMs where hydrography intersects roads, canals, and other anthropogenic features to ensure accurate hydrologic surface flow.
Facilitate quality control/assessment reviews of initial delineations by hydrologists using web-based GIS applications.
Manage data associated with hydrographic modeling. These data include interim raster products, final hydro-flattened/enforced DEMs, breaklines, channel initiation points, etc.
Perform transactional edits on the National Hydrography Dataset (NHD).
Maintain critical attributes from existing NHD features while replacing geometry with LiDAR-based delineations.
Perform quality control and adjustments to hydro breaklines, waterbody features digitized from imagery, and hydrologic unit boundaries.
Ability to effectively communicate orally and in writing
Proficiency with the ESRI ArcGIS version 10.x software suite, including the spatial analyst extension
Demonstrated experience editing vector-based data in ArcGIS version 10.x software in a production environment
Demonstrated experience managing, processing, and analyzing raster datasets to model hydrography
Familiarity with the high-resolution National Hydrographic Dataset (NHD) requirements and data standards
Understanding of basic hydrologic science principles
Experience with performing geospatial statistical analysis
Experience designing and editing geodatabases with related tables to a state or national standard
Experience producing and/or maintaining editable feature services in ArcGIS web applications
