Harmonisation approach Determining a is the reference

Harmonisation approach • Determining a is the reference dataset in term of harmonisation to producers, which 1. Data that we have in 2. Harmonise them at the most useful and cost efficient to do so 3. maintenance and derivation NDB similar scale NDB 1 NDB 2 Nat. Harm. Core Euro. Regional. Map Nat. Harm. Core NDB larger scale 2

Harmonisation approach • Map resolution allowed • Data content restricted to maintained by mapping agencies • Basic spatial analysis requirements • • usually of transport and water network of administrative boundaries 3

Conceptual Model • Level 3 topology • Node-to-edge, Face-to-edge • Simple primitive • Feature Class • • • Set of features sharing a homogeneous set of attributes Point, area, line, text FACC DIGEST except italics* Feature Class Name WATERCRSL Feature class Type Line Feature Codes BH 502 Attributes EXS, HOC, HYC, LOC, NAM, NA 2, NLN 2, WD 7, WD 8 * 5

Administrative boundaries Content • Lowest level (commune) • Integration of SABE attributes with relate tables SABE. NAM and SABE. ISN Requirement Mandatory Topology 3, full topology Requirement Consistent geometry with water network ( at least for international boundary *) User Purpose Geo-spatial analysis Visualisation Location Arc/Info Model BNDNET (arc, poly) 6

Water Network Content • Water Network (BH 502) • Navigability, Name, Classification (WD 7, WD 8) • Water area, ice • Ponctual features Requirement Most Mandatory Topology 3, full topology requirement Full connectivity by portraying fictitious axis in open water and underground network User Purpose Geo-spatial analysis Visualisation Location Arc/Info Model HYDRONET ( arc, poly, node) HYDROPOINT ( point ) 7

Vegetation and Soil Content • Trees, Orchard, Sand area Requirement Woods mandatory Topology 3, full topology requirement Nothing specific User Purpose Visualisation, cartographic applications Arc/Info Model VEGPOLY (poly) 8

Miscellaneous Content • Power lines • Building, Landmarks, Industrial el. , Towers, Physical el. • Natural parks Requirement Most optional Natural parks mandatory Topology 3, full topology requirement Nothing specific User Purpose Visualisation, cartographic applications, location (name) Arc/Info Model MISCPOLY (poly) MISCLINK (arc, point) 9

Transport Content • Road network • Railway network • Airfields, Harbours • Ferry lines, • Stations, parkings, level crossings, interchanges Requirement Most Mandatory Topology 3, full topology Requirement Full connectivity of road and railway network User Purpose Intelligent transport systems, Location based services, Arc/Info Model Map display , visualisation TRANSNET (arc, poly) TRANSLINK (arc, node, point) 10

Settlement Content Built up area: • Name • population range (PP 1 PP 2 ) • Named location Requirement Mandatory Topology 3, full topology Requirement Selection consistent with the road network User Purpose Visualisation, LBS, Planning Arc/Info Model POPPOLY (poly) POPPOINT (point) 11
