Twin Pipelines Mapped in Alaska with Ultra High Resolution Multibeam Sonar
eTrac is added as a USACE prime contractor for coastal surveying services for the Alaska district. Contract performance period is 3 years with broad geographic coverage in the state. We are excited and honored to be added to this contract. eTrac supports USACE with hydrographic surveying services in various USACE districts.
Multibeam data was collected using an R2 Sonic 2024 coupled with an Applanix PosMV Position and Motion system. Modeling was performed in AutoCAD Civil 3D. The data will be used to assist engineers in a seismic upgrade to the pier scheduled for 2015.
