• INfrastructure for SPatial InfoRmation in Europe (INSPIRE)

• Laid down in INSPIRE Directive (accepted by EC May 2007), in Implementing Rules, (many !) guideline documents …

• Aim: “establishing an infrastructure for spatial information in Europe to support Community environmental policies, and policies or activities which may have an impact on the environment”

enable exchange of spatial information between the member states to support environmental policies

Keywords: Harmonization, Metadata, Services, Infrastructure …

• This leads to Interoperability, standards (and OGC !)

INSPIRE Overview

OGC®

INSPIRE data specification

• What data ?• A Drafting Team (DT) has provided a high level definition of data

themes, laid down in 3 annexes :• Annexe I and II : “Basic” geographic data

• CRS, Grid Systems, Addresses, Cadastral Parcels, Hydrography …• Elevation, Orthoimagery, Geology ..

• Annexe III : Themes directly linked to DWG Met-Ocean concerns • Human Health and Safety (Air quality (O3, NO2, SO2, UV, aerosols)).• Natural Risk Zones• Atmospheric conditions (Precipitation, wind, clouds, lightning, temperature, UV) • Meteorological geographical features (Synoptic observations, clouds,

precipitation.)• Oceanographic geographical features• Sea Region (Sea water temperature, sea level)

OGC®

Main INSPIRE milestones

• December 2013:

Metadata available for spatial data corresponding

to Annex III

• January 2015: Newly collected and extensively restructured Annex II and III spatial data sets available.

• May 2019: Other Annex II and III spatial data sets available.

• III-13 Atmospheric Conditions:– Physical conditions in the atmosphere. Includes spatial data based on

measurements, on models or on a combination thereof and includes measurements locations

• III-14 Meteorological Geographical Features:– Weather conditions and their measurements: precipitation, temperature,

evapotranspiration, wind speed and direction

!!! What is the difference between III-13 and III-14? Distinction is not so clear & scope potentially very large

TWG - AC+MF from the directive

OGC®

The scope

• No guidance available on the range of information to be covered by AC + MF:– Inclusion of forecast data?– Precise list of parameters?– Spatial and temporal resolution?– Vertical dimension?– Etc.

• Detailed review of available documents yields no a priori reason to exclude any type of meteorological information=> critical question: feasibility and affordability.

• List of mandatory parameters for the initial implementation: basic meteorological parameters required for the reference use case

OGC®

TWG - AC+MF approach

• Develop Use Cases and use them to focus on which data are really needed

– Treat AC & MF as single theme for initial development of data specification

• Ensure coherence with other, highly significant, development work underway:

– Data and services specification in OGC MetOcean Domain Working Group

– New WMO Information System• both aiming at interoperability of meteorological information

The modelThe modelISO 19156 (Observations and ISO 19156 (Observations and

Measurements)Measurements)

• the AC-MF conceptual schema is rooted on the common base conceptual model of Observation and Measurements (O&M) defined in ISO 19156:2011 which introduces the concepts of observation and spatial sampling feature.

• Observation: is an act that results in the estimation of the value of a feature property of a feature of interest using a designated procedure.

• Spatial sampling feature: the applied sampling regime required where exhaustive observation of environmental parameters is not possible – for example, there is no observation that can provide air temperature values of the whole atmosphere above London.

• Central place given to “Atmospheric Condition”: aggregation of one or more instances of OM_Observation

• Examples of such aggregation:– an entire result set (all parameters, all times, all levels) of a single

model run– all observations collected from a single ground observation station

within one collecting period (1 minute - 1 day)– all observations collected from all available ground observation

stations within one collecting period (last 3-6h)– all possible weather information available for a given region over a

given time period– all air traffic related meteorological information considering two

given airports and the airspace between– any distinct data set containing meteorologically interesting data

• The Directive states that atmospheric data can originate from measurements, models, or post-processed information combining measurement and model output.

• AtmosphericConditionProcess shall provide information

regarding the procedure used to generate the result for each observation member of AtmosphericCondition.

• This set of information consists of the following information

pieces: identification, type and further documentation of the applied

procedure; individual(s) and/or organisation(s) related to the procedure; names of parameters controlling the procedure’s output.

• AC-MF model adopts the CSML observation types - specialisations of sampling coverage observation - each corresponding to a particular spatiotemporal sampling geometry and related coverage result [OGC pending document 11-021].

• CSML will be external to AC-MF model in the future versions.

Phenomenon model

• The phenomenon model was removed from SWE Common 2.0• Ongoing work on a new phenomenon model (Dominic Lowe) • The new phenomenon model will handle « composites » and

« complex » observed properties • The INSPIRE phenomenon model will probably have to be harmonized

accordingly• WMS layers are based on Observed Properties• The Observed Property is also a crucial discriminator for data

discovery

OGC®

CSML dependencies

• CSML types are embedded in the AC-MF model, but CSML will have to be external to AC-MF (and available somewhere in the foundation Inspire schemas)

• CSML observation types (i.e ProfileObservation ) directly extent OM_Observation, because DiscreteCoverage and SamplingCoverageObservation are only « informal » in O&M 2.0

• Maybe, it would be useful to define elementary and generic enough domain feature types and sampling feature types in our model

• Define schematron rules to set additional constraints related to missing types (SamplingCoverageObservation, …)
