A Design and Implementation of Ocean-Bottom Seismometer Position System Based on GIS

Abstract

As the Ocean-Bottom Seismometer (OBS) in the engineering work put in difficulties and position inaccurate practical problems, the position support systems for OBS has been designed and developed to accurately record the process, accurately locate the submarine position of OBS, for the recovery services. This system mainly consisting of decision making databases, GIS platform, application modules and graphical user interface (GUI). First, we describe the methodologies and Principle of OBS launch position in this system, in this paper, and Analysis the advantage by integrated the GIS engine. And then the Schematic overview of the position support system is designed, the functions and implementation of the application module are detailed. A position model which integrates USBL and pseudo range positioning to determine the location of OBS on the seabed presented. Finally, the system implementation are described and illustrated with application figure to familiarize users with the system and its usage. The main advantage of the system is that it considers the demand of lightweight for Spatial Data Engine, integrates GIS engine, achieves with hierarchical modular method. Users are able to obtain information of OBS using an intuitive interface, which supports visualization and analysis via a series of operation of software.
