Top10Vector - Hydrography
s'Top10Vector – Hydrography' is the dataset of the Belgian hydrography. This dataset comprises 6 feature types. The basis of the hydrographic network is formed by watercourse segments [HY_watercoursesegment]. The surface of larger watercourses is represented by watercourse surfaces [HY_watercoursesurface]. Water surfaces [HY_watersurface] and wetlands [HY_wetland] are also included in the dataset. Water points [HY_waterpoint] are point features where water reaches the land surface naturally or disappears into the subsoil. Another type of point feature is the kilometre marker [HY_waterwaykilometremarker].
The dataset can be downloaded via the links in 'Access' at the bottom of this page.

- Purpose
-
Top10Vector is a vector dataset 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 35 feature classes, which are grouped in eight themes: road network, railway network, hydrography, high-voltage 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 downloaded in the form of a GeoPackage or Shapefiles.

- 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.
