Terminology and definitions For the purposes of these product specifications, the following definitions apply. Attribute Characteristic of an object (type). Note: In an object catalogue, an attribute of an object type is determined by a name, a definition, a data type, and the possible values that can be assigned to this attribute (attribute domain). In a data set, an attribute of an object is determined by a name and the attribute value of the object. Object catalogue Catalogue containing the definition and description of object types, attributes, and object relationships that occur in one or more data sets. Where appropriate, an object catalogue also contains the operations that have been defined for the object types. Object (type) An object is an abstraction of an occurrence from the real world. An object type is determined by a definition and can have several attributes. The behaviour of an object type can be determined by operations. The links between object types or between different objects of the same type can be determined by relationships. 1.3.

PRODUCT IDENTIFICATION 3.1. Title AdminVector v4.1 (2019) 3.2. Brief description AdminVector is the vector data series that contains the most geometrically accurate and semantically detailed administrative vector data. These data come directly from their respective authentic sources and are integrated into a single digital series by the NGI. The data set includes 12 classes of objects covering statistic sectors, municipal sections, municipalities, districts, provinces, regions and the territorial and maritime boundaries of Belgium. The geometry of the data for all these topics is described by X,Y or X,Y,Z coordinates. AdminVector is available for the entire Belgian territory and can be supplied as an ESRI File Geodatabase or as shapefiles. 3.3. Scope AdminVector contains the data used primarily to produce administrative and topographic maps. However, when producing vector data, data movements or any other form of generalisation for these mapping applications are avoided. In effect, these data constitute a geographical reference inventory of the Belgian territory and can consequently form the basis for a wide range of applications. Where possible, external thematic identification codes have been associated with AdminVector to facilitate linking to other data sets. 3.4. Topics − Basic mapping − Administrative boundaries 3.5. Type of spatial representation − Vector data with X,Y,Z coordinates. 3.6. Spatial resolution − Equivalent scale: 1:10,000 3.7. Geographical demarcation AdminVector is available for the entire Belgian territory The coordinates below demarcate a rectangular area within which all data are located. Expressed in decimal degrees ETRS89: − degree of longitude west side: 2.2° W, − degree of longitude east side: 6.45° W, − degree of latitude south side: 49.45° N, V4.1 (2019) AdminVector Product specifications Page 5 of 28 − degree of latitude north side: 51.9° N. Expressed in Lambert 2008 coordinates: − X coordinate west side: 500,000 m, − X coordinate east side: 800,000 m, − Y coordinate south side: 515,000 m, − Y coordinate north sides: 790,000 m. Expressed in Lambert 72 coordinates: − X coordinate west side: 0 m, − X coordinate east side: 300,000 m, − Y coordinate south side: 15,000 m, − Y coordinate north sides: 290,000 m. 4.
