Abstract:
|
Effective ocean and coastal data management are needed to
manage marine ecosystem health. Past ocean and coastal data management
systems were often very specific to a particular application and region, but
this focused approach often lacks real-time data and sharing/interoperating
capability. The challenge for the ocean observing community is to devise
standards and practices that enable integration of data from sensors across
devices, manufacturers, users, and domains to enable new types of applications
and services that facilitate much more comprehensive understanding
and analyses of marine ecosystem. A given kind of sensor may be deployed
on various platforms such as floats, gliders or moorings, and thus must be
integrated with different operation, and data management systems. Simplifying
the integration process in existing or newly established observing
systems would benefit system operators and is important for the broader application
of diverse sensors. This paper describes a geospatial “sensor web”
architecture developed by the “NeXOS” project for ocean and coastal data
management, based on the concepts of spatial data infrastructure and the
Sensor Web Enablement framework of the Open Geospatial Consortium.
This approach reduces the effort to propagate data from deployed sensors
to users. To support the realization of the proposed Next generation
Ocean Sensors (NeXOS) architecture, hardware and software specifications
for a Smart Electronic Interface for Sensors and Instruments (SEISI)
are described. SEISI specifies small lower-power electronics, minimal operating
system, and standards-basedresearch software to enable web-based sharing, discovery, exchange, and processing of sensor observations as well
as operation of sensor devices. An experimental scenario is presented in
which sensor data from a low-power glider with low-bandwidth intermittent
satellite communications is integrated into the geospatial sensor web
using the NeXOS architecture. |
