Meeting on OGC Sensor Observation Service (SOS) for INSPIRE

Rafał WartanowiczInstitute of Meteorology and Water Management

- National Research Institute (IMGW-PIB)

Previous SOS experiences

Scope: Self study on possibilities to implement SOS

Delivered content: potential content for SOS includes meteorological measurements which are collected as time series at measurement stations located in Poland

Previous SOS experiences

Delivered content: infrastructure for content is based on project C2.6 which does not contain GIS software but contains sources of measurement data and ISOK project which is based on ESRI GIS infrastructure.

Discussion: Why an INSPIRE/SOS?In my opinion:• SOS services are very good as additional option for

delivery of small amount of up-to-date measurement data in form of time series from monitoring stations, this protocol solves also problem of delivery of metadata of the nodes of measurement network

• WFS (pre-defined data sets) very good for delivery of moderate amount data from discrete geospatial features

• ATOM (pre-defined data sets) very good and practical for delivery of URLs to large amount of data from discrete geospatial features

Discussion: Wish list• Which features would you like to see in an INSPIRE

download service for observation data?

SOS would be good additional option in INSPIRE download service.

Additional informationMaybe some ideas like: option for• JSON• RestFul approach • Compression• Packaging (good for caching algorithms)

would also useful as a part of SOS standard implementation
