2 Outline ERFF, LWEC, UK EOF INSPIRE Methodology: MOLES, EMF, ISO Data model: MonitoringActivity, MonitoringFacility, Instrument Funds ObservationCollection Summary

3 ERFF, LWEC Environmental Research Funders Forum was a grouping of the major UK funders of environmental research (incl. Defra, EA, Met Office, NERC, etc.) announced 10 June that it would merge with... Living With Environmental Change a ten-year partnership between Research Councils, government departments, devolved administrations, delivery agencies aims to strengthen the evidence base for policy by aligning 1bn investment in first 5yrs

4 UK EOF UK Environmental Observation Framework, established to: identify and address the issues surrounding environmental observations made for and by the UK will enable funders and users to: see the entire observation/monitoring portfolio, understand the motivations of its various components, and will improve data accessibility and quality

5 Environmental Observation Activity Catalogue An initial implementation allows searching ( Who, What, Where, Why ) for a large number of UK monitoring activities A second phase will expand the information Addressed to three classes of users: funders and decision-makers for a strategic overview (for instance to aid coordination of resourcing) program managers as a tool for efficient implementation of monitoring data users to facilitate discovery and access to monitoring data In addition, it should include data suitability elements (e.g. whether metadata standards have been applied, how data is made available, etc.)

6 UK EOF data model This project was focussed on developing a data model for UK EOF support use cases conform to emerging standards Adopted INSPIRE methodology: UK NERC MOLES AWWB EMF candidate ISO standards ( , 19156) Who, What, Why, When, Where... Decision-makers, program managers, data users...

11 MonitoringActivity An identifiable activity that generates observations by deploying instruments at one or more monitoring facilities. It includes monitoring networks, fixed deployments, flights, cruises, field trips, computations etc. Targeted programmes of monitoring (projects) are also included. Information is included on the activities objectives and associated legislation. A Monitoring Activity may be comprised of a number of child monitoring activities.

12 MonitoringFacility A facility at/from which instruments are hosted or deployed to undertake environmental monitoring (in-situ or remotely sensed); either a static observation site or a moving platform. Hierarchies of monitoring facilities are allowed, for instance identifiable observation sites comprising a larger observation site.

13 Instrument An instrument or instrument system which may be used in making an observation. May include human observer protocols.

14 A source of funds associated with a monitoring activity (including programmes and projects). It includes the nature of the resource (e.g. whether cash or inkind), and its status (e.g. ongoing or fixedterm). Funds

15 ISO Observations and Measurements A recurring pattern: an observation measures some observed property of a feature of interest using a procedure, generating a result class Overview: Observation GFI_Feature +featureofinterest GFI_DomainFeature +propertyvalueprovider 1 GFI_PropertyType SF_SamplingFeature Intention 1..* +sampledfeature 1 +generatedobservation summarised into: OM_Observation + parameter [] + phenomenontime + resultquality [] + resulttime + validtime [0..1] +observedproperty 1 Range +result OM_Process +dependency +procedure ObservationCollection Any

16 ObservationCollection A collection of observations generated through a monitoring program or activity. Usually corresponds to a dataset (probably conforming to a theme-specific data model). Also includes usability information and access constraints. Summarises details of sampling location, observed properties, and procedures (instruments) used within a dataset.
