In order to test the different prototypes created in the project a series of datasets have been compiled and evaluated. The quality of the datasets and their suitability for the targets of the project determine the scope and reliance on the results. In the frame of GEOSS, potential data providers, clients and, in the end, users of geospatial data must also be taken into account. Three main aspects will be considered:

  • the dataset in itself (sources, methods, parameters, topics covered, social impact)
  • associated quality data of the dataset (quality measures of raw data and products)
  • data chain (e.g., discovery time, propagation, services, delivery, stakeholders)

The pilot cases description template and several discussions within GeoViQua generated the definitive selection criteria for the pilot case testing datasets:

  • provenance and traceability: prioritizing contributions from partners and/or datasets registered in GEOSS Global Common Infrastructure (GCI) Component and Services Registry (CSR).
  • contributors expertise: guarantee comprehension of the dataset (control on sources, processes, data peculiarities, data description, potential use)
  • availability (or else retrieval system) and reliability of associated quality parameters
  • suitability for experimental testing
  • variety: cover the wider range of fundamental aspects (e.g., data sources, methods, quality measures, scales,parameters) in order to assure an optimized match between the dataset features and the corresponding experimental tests
  • scenarios building capacity
  • suitability for dissemination purposes
  • topic and social impact: cover a wide range of thematic areas as derived from the Description of Work including parameters highlighted in the critical Earth Observation priorities list, sticking to GEOSS SBAs and CoPs

Regarding the last point, the selected datasets were to be in accordance with the Critical Earth Observation priorities list, derived from the GEO Task US-09-01a. This task seeks to identify Earth Observation needs across a full spectrum of user types and communities both within each SBA and across all SBAs, including observation needs from a variety of geographic regions and significant representation from developing countries . This list includes ground, in situ , airborne, and space-based observations. The focus is on both observed and derived observation parameters as well as model products. As a result, a complex sample will be subjected to several experimentation tests related to WP7 objectives (quality parameterization, validation of search components, quality aware visualisation, and validation of the GEO Label). This variety intends to be representative of situations commonly faced by all potential users (scientists, technicians, decision makers, politicians, disseminators, teachers, students or general public) in their daily activities with geodatasets, setting an example of real cases.
