Post-condition The information obtained can help user to make decisions. <strong>Data</strong> source: INSPIRE-Conformant Orthoimagery Provided by National Program of Remote Sensing (PNT) and water need parameters by Member State User can access orthoimagery, in official map projection ETRS-89, by File • Description Transfer Protocol (FTP). Report data generated for agriculture water needs to provide summary details across Europe. • <strong>Data</strong> provider Each member state or other national, regional or local providers. Geographic scope Europe wide, although a smaller area may be selected. Thematic scope INSPIRE Annex II. Orthoimagery. Scale, resolution A Minimum resolution threshold is required, which crops areas can be defined. About 30 metres of pixel size at least.

The scenario for the Demarcation update of agricultural plots at regional level for inventory record and funding is that a specific owner of agricultural plots should be able to consult the inventory record concerning his properties and update it by using detailed and as recent as possible existing orthoimages of the area. Once the information is updated, a funding request in agreement with the Common Agricultural Policy (CAP), should be automatically processed. It must be taken into account that Member States can introduce regionalised payments for a whole region or country. Use Case Description Name Demarcation update of agricultural plots at regional level for inventory record and funding. Priority high The user, who is the owner of an exploitation, uses a publicly accessible GIS to find, either through zoom/pan tools or, by gazetteer search, his Description different agricultural plots clearly drawn over the most recent available orthoimages of the area. In case of changes with respect to the existing information, the user may update, by using web-based tools, the graphical information and attributes for any specific plot. Quality-controlled agricultural data, together with the orthoimagery, is available to the user according to INSPIRE specifications and the INSPIRE Pre-condition registry provides all the necessary information for standardised access to data. The images used to generate the orthoimagery must have been acquired during a period consistent for the updating task. Flow of Events – Basic Path • Step 1. The user calls a Web Processing Service and logs into the system by providing user identification. • Step 2. The Web Processing Service displays the list of plots belonging to the user. The user may select specific plots and display their boundaries over the • Step 3. most recent available orthoimages with enough resolution for the application purposes. The user may select a specific plot, maybe composed of several polygons, and activate an updating application able to make several graphic • Step 4. operations: zoom in/out, polygon merging, polygon division, deletion and creation of polygons, boundary modification, etc. Labelling of the contents of those polygons should also be available. • Step 5 The user may download the data related to his property (KML, …) Post-condition The user obtains some kind of certificate of update for their declared exploitations.
