2. System Tools Spatial Validation Process: GISVal Tool Descriptive and Spatial Data Loading: N2K Loader ToolBox Spatial Data Publishing Tools: N2K Generalization Toolbox Data Assessment: AreaCalculation Toolbox DataBase Model

3. GISVal Application Purpose: Used for the spatial validation – Consistent representation of the sites in both databases (descriptive + spatial) – The position of the centroid calculated by GIS and compared with descriptive data values – The area calculated by GIS and compared with descriptive data values Input: MS Shape Files + BioTop table Output: Personal Geodatabase + ArcGIS map document Technological Environment: ArcGIS 9.3

4. N2K Loader Toolbox Purpose: Used to load validated data into N2K database (Spatial + Descriptive) Input: CNTRY.mdb + MS shapefiles Output: N2K Database (ETRS89) Technological Environment: – SQL Server 2005 or 2008 – ArcGIS 9.3 – Python 2.5

5. N2K Generalization Toolbox Purpose: This toolbox is used to generalize N2K spatial data to be integrated into web environment Input: N2K raw sites (polygons in ETRS89) Output: N2K sites scaled to 1:100K, 1:1M and 1: 10M (ETRS 89 LAEA) Technological Environment: – ArcGIS 9.3 – Python 2.5

6. Area Calculation Toolbox Purpose: Analyse area distribution of N2K sites by MS and for EU27 – Area and count of all marine SPA, SCI and C sites – Area and count of all terrestrial SPA, SCI and C sites – Marine area overlap between SCI and SPA sites – Terrestrial area overlap between SCI and SPA sites Input: N2K100K_LAEA feature class Output: Personal Geodatabase + Excel sheet Technological Environment: ArcGIS 9.2 + Python
