Abstract
In the mine warfare community, a mission consists of mapping the ocean floor using sonar technology, a process that generates gigabytes of files. These files contain the metadata and the sonar image packed in a proprietary version of the TIFF image file format, as specified by the sonar vendor. Mission data has been collected for decades, yet there is no way to catalog, search, and extract analytics from historical information. Using the Java programming language and a Hadoop Distributed File System (HDFS) cluster of servers, the Naval Postgraduate School (NPS) managed to extract information and store it in a not only SQL (NoSQL) database (HIVE). Using a HDFS-to-Oracle database data transfer tool (Sqoop), a subset of the data was then moved to a relational database schema which opened up the ability to combine with Google Maps. Integration of the visualization (maps) and search was provided by the database vendor add-on known as Application Express (APEX). Mine identification is a separate research project that involves analyzing the image portion of the file, and is a major Navy effort. The NPS-Computer Science (CS) team explored artificial intelligence (AI) algorithms for mine identification, and were encouraged by the results (research in progress). Given the cost overruns of any project, the team also demonstrated that the needed hardware/software can be assembled and installed to build a cost-effective system using open-source technologies.
