Implementation of Sensor Observation Service for Satellite Imagery Sensors

Abstract

This research takes advantages of Sensor Observation Service (SOS), according to a grid-based satellite sensor: Geostationary Operational Environmental Satellites (GOES) to construct a framework to serve GOES data with standard interfaces. The implemented SOS operations here are Get Capabilities to serve the service metadata about the specific service instance, Describe Sensor to serve detailed sensor metadata and Get Observation to retrieve observation data structured according to the Observation and Measurement specification. Two major problems occurred in the implementation will be discussed in this Paper: One is how to retrieve real-time GOES data automatically since the sensors keep collecting data and the other is how to modeling sensor observations. A data order system is designed to achieve the goal of retrieving GOES data. The Observation and Measurements (O&M) specification which can handle lots of data types in an efficient and robust way is adopted to solve the second problem.
