ROV geographic information system upgrades
Lead Scientist: Jim Barry
This proposal addresses problems with the integration of remotely operated
vehicle (ROV) navigation data
and the ‘real-time’ MBARI-specific extensions to a commercial Geographic
Information System (GIS) package. We also propose to improve our at-sea access
to the Western Flyer/Tiburon core data-streams during long
expeditions.
a) ROV Real-time GIS Upgrade
ArcView GIS software has been used very effectively with the MBARI ship / ROV
systems to track dives in relation to high-resolution basemaps, integrating
available map data with ROV operations and science goals. ArcNav is the
name of the real-time GIS tracking software extensions package written by Gerry
Hatcher in 1997 and used extensively on both MBARI vessels. These extensions
enable scientists and ROV pilots to navigate the vehicle over ArcView GIS
basemaps in real-time and permit users to mark points with comments and vehicle
data directly into their ArcView projects. Users have come to rely on the ‘markpoint
files’ created by this system. These files contain the map locations along
with the comments and associated vehicle navigation data. One objective of this proposal is to modify the ArcNav scripts to ensure
that the data currently being collected in the ‘markpoint files’ can be
linked to and archived with other mission data in the navigation database.
b) Western Flyer Data Integration
Efficient ship/ROV operations are compromised by the current post-cruise
'batch' nature of dive information processing, in which the expedition database
and archives are updated only when the vessel returns to home port or when the
data is hand-carried back. In either case, data is still not as easily
accessible on-board for the duration of the voyage. A portion of this proposal
will address making relevant portions of the expedition database and newly
acquired, minimally processed, data more immediately accessible at sea on the Western
Flyer.
