Query: Towards Realisation of Heterogeneous Earth-Observation Sensor Database
  Framework for the Sensor Observation Service based on PostGIS   Environmental monitoring and management systems in most cases deal with
models and spatial analytics that involve the integration of in-situ and remote
Geosensor observations. In-situ sensor observations and those gathered by
remote sensors are usually provided by different databases and services in
real-time dynamic services such as the Geo-Web Services. Thus, data have to be
pulled from different databases and transferred over the network before they
are fused and processed on the service middleware. This process is very massive
and unnecessary communication-work load on the service middleware. Massive work
load in large raster downloads from flat-file raster data sources each time a
request is made and huge integration and geo-processing work load on the
service middleware which could actually be better leveraged at the database
This paper therefore proposes the realization of heterogeneous sensor database
framework based on PostGIS for integration, geo-processing and spatial analysis
of remote and in-situ sensor observations at the database level. Also discussed
in this paper is how the framework can be integrated in the Sensor Observation
Service (SOS) to reduce communication and massive workload on the Geospatial
Web Services and as well make query request from the user end a lot more
flexible. Keywords: Earth-Observation, Heterogeneous Earth-Observation Sensor
Database, PostGIS , Sensor Observation Service.
