摘要：Accurate and fine-grained discovery by diverse Earth observation (EO) sensors ensures a
comprehensive response to collaborative observation-required emergency tasks. This discovery
remains a challenge in an EO sensor web environment. In this study, we propose an EO sensor
observation
capability
metadata
model
that
reuses
and
extends
the
existing
sensor
observation-related metadata standards to enable the accurate and fine-grained discovery of EO
sensors. The proposed model is composed of five sub-modules, namely, ObservationBreadth,
ObservationDepth, ObservationFrequency, ObservationQuality and ObservationData. The model is
applied to different types of EO sensors and is formalized by the Open Geospatial Consortium Sensor
Model Language 1.0. The GeosensorQuery prototype retrieves the qualified EO sensors based on the
provided geo-event. An actual application to flood emergency observation in the Yangtze River
Basin in China is conducted, and the results indicate that sensor inquiry can accurately achieve
fine-grained discovery of qualified EO sensors and obtain enriched observation capability
information. In summary, the proposed model enables an efficient encoding system that ensures
minimum unification to represent the observation capabilities of EO sensors. The model functions
as a foundation for the efficient discovery of EO sensors. In addition, the definition and
development of this proposed EO sensor observation capability metadata model is a helpful step
in extending the Sensor Model Language (SensorML) 2.0 Profile for the description of the
observation capabilities of EO sensors.
