2 OPEN GEOSPATIAL CONSORTIUM (OGC) Standards organization, originated in 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.

3 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 Web Processing Service WPS a standard for exposing process requests (input) and responses (output) from different data sources Web Catalog Service CSW a standard for exposing a catalogue of geospatial records on the web apr 29-apr 19-mag 8-giu 28-giu 18-lug Q sim Q mis

4 OPEN GEOSPATIAL CONSORTIUM (OGC) STANDARDISED SENSOR METADATA - to automatically ingest/import/exchange DATA SENSOR WEB ENABLEMENT (SWE) open geospatial consortium (OGC) and W3C standard SWE = O&M + SensorML capacity of systematic acquisition insitu measurements/observations on-line accessibility to data (O&M) and sensor metadata (SensorML) implementation of SWE services within Spatial Data Infrastructures (SDI)

5 SENSOR METADATA LANGUAGE - SENSORML OGC XML schema for describe instruments: STATIC CONTENT General Info DYNAMIC CONTENT Histories Parameter

6 OBSERVATIONS & MEASUREMENTS (O&M) 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.
