DataView - an application for visualising
and distributing seabed data
Seabed observations come in a variety of georeferenced data sets
including, acoustic, video, photographic and physical capture (sediment
and biota) information. These data need to be quality checked,
displayed and synthesized for a range of research, management and
stakeholder uses. We concentrate here on the need of researchers to
share, quality check and cross-reference the observational data in a
timely manner. An associated need is the ability to distribute and view
observational data without the need for extra software costs. A program
"DataView" was developed that represents the first steps in
addressing
these needs.
DataView, written in Java using CMRlib, is a special purpose GIS system
customised to our data and currently supports the following
georeferenced data sets:
* Classified video clips of the seabed (not supported by commercial
GIS
systems),
* Bottom type indices generated from single beam acoustics, including
display of acoustic footprint,
* Survey information from legacy system data files,
* Ship's operations and underway data from data center databases,
* Drop camera photographs and video frame grabs,
* Biota catch summaries with species descriptions,
* Sediment samples with photographs and analyses,
* Generic support for any georeferenced data held in an SQL compliant
database.
DataView gets the majority of its data from database tables and has
support for multiple data sources. Using Java technologies, database
tables can be stored in text files and written to CD in a format that
is both human readable and database accessible. A demonstration of the
software and its portability will be presented.
This program may be of interest to any researchers with two dimensional
georeferenced data they wish to visualise or distribute to
stakeholders.
