Section 4: Provisioning Data through a Sensor Observation Service

<<Prev T.O.C Next>>


4.1 Requirements

The next two sections describe approaches how to publish sensor data through a OGC Sensor Observation Service (SOS). There is only one requirement for this: you need an installed version of the SOS that supports the transactional SOS operations for inserting new sensors and sensor data via an HTTP interface. This tutorial is based on version 1.0 of the SOS specification, so that the used SOS has to support this version of the specification.

An example for such an implementation is the 52°North Sensor Observation Service (http://52north.org/sos ). For more information on the installation please refer to this guide.

If you are aware of other SOS implementations, any feedback on compatibility issues is appreciated. Furthermore, additional chapters applying to different SOS implementations are very welcome.

4.2 Summary of Steps

This page contains two step-by-step guides different approaches to publish sensor data through a OGC Sensor Observation Service (SOS). The first one is based on the direct use of the transactional operations of the SOS interface. It is mainly intended for programmers who want to connect sensors or data pools directly to the SOS.

The second approach is intended for a broader range of users that have sensor data archives available in a file-based structure. This proposal shows how such files (more specifically comma-separated values (CSV) files) can be published using a SOS import tool that hides the SOS-specific XML protocol and consequently is more user friendly.
