Self Consistent Bathymetric Mapping Using Sub-Maps: Survey Results From The Tag Hydrothermal Structure, C. Roman, R. Reves-Sohn, H. Singh, S. Humphris Dec 2005

Self Consistent Bathymetric Mapping Using Sub-Maps: Survey Results From The Tag Hydrothermal Structure, C. Roman, R. Reves-Sohn, H. Singh, S. Humphris

Christopher N. Roman

The spatial resolution of microbathymetry maps created using robotic vehicles such as ROVs, AUVs and manned submersibles in the deep ocean is currently limited by the accuracy of the vehicle navigation data. Errors in the vehicle position estimate commonly exceed the ranging errors of the acoustic mapping sensor itself, which creates inconsistency in the map making process and produces artifacts that lower resolution and distort map integrity. We present a methodology for producing self-consistent maps and improving vehicle position estimation by exploiting accurate local navigation and utilizing terrain relative measurements. The complete map is broken down into individual "sub-maps'', which …
