Purpose

Top10Vector contains the data which are used in the first place to make topographic maps at the scales of 1:10 000 and 1:20 000. However, shifting data or other kinds of generalisation for these cartographic applications are avoided during the production of these vector data, as they constitute a geographic reference inventory of the Belgian territory and as such they can be used for a wide range of applications. Whenever it was possible, external thematic identification codes have been linked to Top10Vector in order to facilitate the links with other data sets.

Statement

For this data set, the NGI aims at an update cycle of 1 year for the road network, 3 years for the constructions and 6 years for all the other themes, The update processes vary according to the theme. The road network and the constructions are updated by means of photogrammetric restitution and field surveys. The geometry of these data is updated in stereoscopy (3D), using recent aerial color photographs. Moreover, some topological rules which apply to this dataset are checked. Next, these data are passed on to the field survey service which will update the attribute data. The update of all the other themes is done by interpretation on orthophotographs and field surveys.First, the geometry and the attribute data are updated in monoscopy (2D), using recent orthophotographs. Next, these data are checked on the field and completed. The NGI collaborates with other organizations for the update of certain themes (re-use of existing data). In order to respect the update cycles whenever it is possible, we sometimes work with subcontractors.
