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

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

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

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

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

N2K Database Components

• UML Database Model• ArcSDE Export Files• ESRI Personal Geodatabase
