INSPIRE Compliance Procedure in the DLS Portal
INSPIRE Directive refers to three Annexes which describe specific data themes in the Technical Documents. These Technical documents give guidelines regarding the category of GIS data that fall within specific Data Themes; describe examples and logical diagrams (UML Models) that show the relation between the various data categories.
The Technical documents describe the Application Schemas, logical meanings that explain how GIS data relate through the different Data Themes. In order to include data in corresponding Data Themes, initially, it must be identified what data exist for specific categories and Data Themes, how these data are being used, what is the classification of these GIS data and how it is used in business level, and what is the structure of the attributes that accompany the GIS data.
The analysis of the GIS data was being performed by the Department of Lands and Surveys in direct and continuous with all stakeholders (Data Providers) in order to identify:
- What data each stakeholder/data owner maintains for corresponding data themes;
- How these data are being used at the business level;
- How are these data being classified;
- What is the structure of the GIS data.
The INSPIRE Directive and the Technical Documents disconnect the "What" must be implemented from the "How" it must be implemented. What must be implemented is defined in theoretical level and how it will be implemented is upon each Member State to decide.
The term "INSPIRE Compliant" means:
- The web services (VIEW-WMS, Download-WFS, Atom) for viewing and downloading must fulfill two criteria; to be compliant as services and to publish data that are compliant with the relevant logical conceptual data models;
- The same rules apply for Discovery-CSW services; to be compliant as services and to publish data compliant with the directive.
Transformation of Data
All the data from the corresponding Data Providers in Cyprus (other Governmental Departments and Services) has been imported into the DLS GIS Database. Through ETL (Export-Transform-Load) scripts, the data was processed so to become INSPIRE compatible. Lastly, through publishing services the data becomes available to the internet via the DLS INSPIRE GeoPortal within the DLS PORTAL.
