Purpose

Top10Vector is a vector data set containing the NGI's geometrically most accurate and semantically most detailed topo-geographic vector data. The data originate from the topo-geographic inventory of the Belgian territory (ITGI) which was build and is maintained by the National Geographic Institute. The dataset contains feature classes, which are grouped in eight themes: road network, railroad netwrok, hydrography, high-tension network, constructions, land cover and vegetation, local relief and particular zones. The geometry of the data of all these themes is described by x, y, z-coordinates. Top10Vector is available for the entire Belgian territory and can be supplied in the form of an ESRI File Geodatabase, shapefiles or gml-files.

Statement

The data have been collected in two different ways: on the one hand, by field survey, writing down the attribute data on mat-pale photographs, followed by the photogrammetric stereo restitution of the geometry in a CAD-file (with Lambert72 xyz-coordinates) and finally the topological cleaning up and the import of the attribute data in a 2D-database. On the other hand, by photogrammetric stereo restitution of the geometry in a CAD-file (with Lambert72 xyz-coordinates), followed by the import (on-site) of the attribute data in the CAD-files and finally the topological cleaning up in a 2D-database.During the dataloading into the new ITGI-model, the contents of the 2D-database have been mapped and converted into a database with Lambert2008-coordinates. The z-coordinate was recovered from the photogrammetric restitution's CAD-files or calculated on the basis of the DTM.
