52°North SOS¶
ウェブサービス¶
52°North Sensor Observation Service (SOS) は、現地もしくは遠隔センサがリアルタイムに蓄積したデータの取得をサポートします。 センサとしては人工衛星に搭載したカメラから、川の水量メーターまで様々な物を取り扱うことができます。
機能¶
- Browser Client: The SOS is delivered with a browser based application. This provides means for administration and configuration of the service instance, as well as sending test requests for SOS operations; appropriate sample requests are included.
- JavaScript Client: The SOS contains a JavaScript application for displaying time series data. With its help, time series will be visualized without any additional software.
- Specifications: The 52°North SOS implements the current specification version 2.0.0 and the previous version 1.0.0 (here no transactional operations). Listed below are implemented operations for each standard version.
- INSPIRE Download Service Extension: Starting with Version 4.2.0 an extension is available that allows the SOS to be used as INSPIRE download service. Background information is provided in a blog post and in the wiki .
- Air Quality Data e-Reporting Extension: Starting with version 4.3.0 is an extension available that allows to provide for the Air Quality Data Flows E1a, E1b and E2a compliant data (the instance on OSGeo-Live is not configured accordingly). In 52°North Wiki the installation and configuration is documented.
- RESTful API for Timeseries: Starting with Version 4.1.1. is an bundle version available, that directly brings the RESTful API . Hence, timeseries can be requested in a RESTful way in JSON encoded requests. More details incl. documentation can be found in the SOS webapp.
- Read more: The track of the details of the implemented functionalities can be found in the 52°North Wiki.
SOS Operations¶
Queries:
- GetCapabilities: for requesting a self-description of the service.
- DescribeSensor: for requesting information about the sensor.
- GetFeatureOfInterest / GetFeatureOfInterestTime (from 1.0): for requesting features (e.g. sensor/measurement locations).
- GetObservationById / GetObservation: for requesting observations.
- GetResult (from 2.0): for requesting sensor data.
- GetResultTemplate (from 2.0): for requesting a template of the result structure that will be returned by a GetResult request.
- GetDataAvailability (from SOS 2.0 Hydrology Profile - OGC Best Practice): for requesting the data availability for certain configurations.
Transactions:
- InsertSensor (from 2.0): for inserting metadata of new sensors.
- InsertObservation (from 2.0): for inserting new observations.
- UpdateSensorDescription (from 2.0): for updating the description of a sensor.
- DeleteSensor (from 2.0): for deleting a sensor/procedure and all related offerings and observations.
- DeleteObservation (extension for SOS 2.0): for deleting an observation.
- InsertResultTemplate (from 2.0): for inserting a result template.
- InsertResult (from 2.0): for inserting results.
Within these operations the following filter operators are possible where applicable:
- Spatial filter: BBOX, using a bounding box.
- Temporal filter: During, with time period.
- Temporal filter: TEquals, with time instant.
