GIS Hydrographic Analyst w/ Sandborn (pdx)

Hydrographic Analyst 
Join Sanborn’s award-winning team! Sanborn is looking for a Hydrographic Analyst to work onsite with our federal government client in Portland, OR. The position will delineate new hydrography in Oregon and Washington where high quality LiDAR-based Digital Elevation Models (DEMs) are available. The new hydrography will be used to update the high resolution National Hydrography Dataset (NHD) and National Watershed Boundary Dataset (WBD). This position is located in Portland, OR.

The Hydrographic Analyst will develop new hydrography delineations using LiDAR-derived Digital Elevation Models (DEMs), imagery, and field collected data, which will be incorporated into the high-resolution National Hydrography Dataset (NHD).

REQUIRED EXPERIENCE:
•Bachelor’s degree or higher in the biological sciences, agriculture, natural resource management or related disciplines appropriate to the position.
•Three years of experience
•Master’s degree preferred in a natural resource science (Biology, Geology, Hydrology, Soil, Range, Forestry)
 
REQUIRED TECHNICAL EXPERIENCE:
•Proficiency with the ESRI ArcGIS version 10.x or Pro software suite, including the spatial analyst extension.
•Demonstrated experience managing, processing, and analyzing raster datasets to model hydrography.
•Understanding of basic hydrologic science principles.
•Demonstrated programming experience with Python.
•Familiarity with the high-resolution National Hydrographic Dataset (NHD) requirements and data standards.
•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.
•Ability to effectively communicate orally and in writing.
 
PREFERRED BUT NOT REQUIRED:
•Familiarity with the physical geography of Oregon and Washington.
•Analytical Math skills
 
TASKS:
•Prepare LiDAR-derived DEMs (e.g., mosaicking, resampling, etc.) at the watershed or subwatershed scale for hydrography modeling.
•Hydro-flatten DEMs to adjust elevations where hydrographic waterbodies, areas, and double-line streams occur.
•Hydro-enforce DEMs where hydrography intersects roads, canals, and other anthropogenic features to ensure accurate hydrologic surface flow.
•Develop and execute Python scripts to model hydrography from prepared LiDAR-derived DEMs.
•Facilitate quality control/assessment reviews of initial delineations by hydrologists using web-based GIS applications.
•Adjust initial delineations and hydro-enforcements based on feedback from hydrologists.
•Manage data associated with hydrographic modeling. These data include interim raster products, final hydro-flattened/enforced DEMs, breaklines, channel initiation points, etc.
 
Deliverables:
•Flow-line, waterbody, and 2d stream area spatial feature classes formatted following the high-resolution NHD data standards.
•Hydrologic DEMs and breakline features.
•Scripts and written documentation describing the entire modeling process.
