REMUS subbottom image processing for integration into ArcGIS

Abstract

The Naval Océanographie Office collects subbottom acoustic data using the Remote Environmental Monitoring Units (REMUS) Autonomous Underwater Vehicle (AUV). The subbottom data are processed using customized playback software that creates a subbottom profile image that can be integrated into ArcGIS 9.2. A REMUS AUV test survey was recently completed that obtained quality subbottom profiler data that were used to demonstrate this image integration approach. Recent improvements in the processing software developed at the Naval Research Laboratory (NRL) have been used to decrease the time and effort required to efficiently utilize and integrate the subbottom profile imagery into the ArcGIS 9.2 product. This new software allows multiple subbottom images to be easily added to the ArcGIS 9.2 project while at sea, providing a more complete representation of the REMUS survey. The efficient integration of the subbottom imagery into an ArcGIS 9.2 project is a significant step in providing a more improved product.
