INTRODUCTION TO OGC’S SENSORML AND O&M: EXAMPLE OF A POSSIBLE SOLUTION Alessandro Oggioni & Holger Dettki

A future for a common bio-logging language? BLS 6, 27 September 2017, Konstanz, Germany OPEN GEOSPATIAL CONSORTIUM (OGC)

Standards organization, originated in 1994. In the OGC, more than 500 commercial, governmental, nonproﬁt and research institutions worldwide collaborate in a consensus process encouraging development and implementation of open standards for geospatial content and web services. OPEN GEOSPATIAL CONSORTIUM (OGC)

principal OGC web services

• Web Map Service WMS a standard for exposing spatial data as a images on the web

• Web Coverage Service WCS a standard for exposing raster data with their informative content on the web

• Web Feature Service WFS a standard for exposing vector data with their informative content on the web

• SensorWeb Enablement SOS a standard for exposing observations and sensors information collected

by in-situ sensors on the web 350 Q sim Q mis 300

• Web Processing Service WPS 250

a standard for exposing process requests (input) and responses (output) from 150 different data sources 100 50

SENSOR WEB ENABLEMENT (SWE) ▸ open geospatial consortium (OGC) and W3C standard SWE = O&M + SensorML

▸ capacity of systematic acquisition in- situ measurements/observations

▸ on-line accessibility to data (O&M) and sensor metadata (SensorML)

▸ implementation of SWE services within Spatial Data Infrastructures (SDI) SENSOR METADATA LANGUAGE - SENSORML

deﬁnes a conceptual schema encoding for observations. While the O&M standard was developed in the context of geographic information systems, the model is derived from generic patterns proposed by Fowler and Odell (1997) and is not limited to spatial information.
