About this file
This is a bathymetry and topography map for Port Orford Jetty in Oregon, showing seaward contours and elevation data. The map displays 2010 bathymetric and topographic survey data acquired through aerial photogrammetric mapping and bathymetric surveying techniques. The document illustrates existing centerline stations and 2010 contours at five-foot intervals, with elevation values referenced to NAVD88 (North American Vertical Datum of 1988) ranging from a high of 120 feet to a low of -40 feet. The map covers the Port Orford Jetty area along the Pacific Ocean in Oregon and includes background topography and imagery derived from the 2010 survey data.
The map notes that smooth areas along the jetty represent data gaps from the 2016 survey effort, occurring in shallow inter-tidal zones that were too hazardous for survey vessel access. These interpolated low-lying areas are incorporated into cross-sectional graphs for analysis purposes. The document was created on January 23, 2019, and appears to be part of a coastal project file managed within a GIS database, indicating ongoing coastal monitoring and management initiatives for the Port Orford area.

THE SMOOTH AREAS ALONG THE JETTY ARE WHERE
NO DATA WAS ACQUIRED IN 2016, LIKELY DUE TO
SHALLOW INTER-TIDAL ZONES TOO HAZARDOUS FOR
A SURVEY VESSEL. THESE LOW-LYING AREAS ARE
INTERPOLATED IN CROSS-SECTIONAL GRAPHS OF THE DATA.
