INSPIRE compliant discovery service for geographic information made available by the Belgian Federal Government.

The web application G-DOC provides information on all Belgian geodetic reference points. These points can be used as starting points or checkpoints to determine coordinates according to the national reference systems. three groups of geodetic reference points are available: 3D points, altimetric points and planimetric points.

Points Of Interest - Cult elements contains point elements relating to the cult, namely churchs (anglican, catholic, orthodox, protestant), mosques, synanogues, buddhist temples, chapels, abbeys, priories and other religious buildings or small monuments in Belgium.

Geodetic markers of which the 3D coordinates are precisely known in common Belgian reference systems.

Points Of Interest - Economy interest contains point elements indicating the location of an economic activity, such as a brewery, wholesale market, (commercial, industrial) building, cooling tower, gas processing/disposal, slagheap, telecommunications, wind turbine, solar panel park in Belgium.

DSM 1m is a homogeneous and regular point grid indicating the height of the Earth’s surface level in order to model its landscape. DSM 1m is achieved by interpolating in Lambert 2008 source data in Lambert 72 and at a 1m-resolution from the Flemish and Brussels Regions, and by adding Lambert 2008 data at 1m-resolution from the Walloon Region.

Top10Vector – Particular zones is the vector dataset of portions of the Belgian territory having a particular attribution which makes them different from the objects in the other Top10Vector-themes. This dataset includes only one class which can be downloaded via the link in 'Access'.

Points Of Interest - patrimonial elements contains point elements relating to the patrimony, namely (water and wind)mill, (historic, commemoration, fortified) building, historic mound, ice house, castle, kiosk, shoring, non-religious monument, monumental stairs in Belgium.

Top25Map is a digital version of the NGI’s topographic cartography on a scale of 1:25 000. These images result from the symbolisation of the objects and themes which are present in the topo-geographic inventory of the Belgian territory (ITGI), which is built and kept up-to-date by the NGI. Top25Map contains all usual themes of the NGI’s cartographic products (land use, transport, hydrography, buildings and constructions, relief,…), as well as the map lettering and the toponyms. The Top25Map cartography is appropriate to hiking.

Top10Vector – Railway network is the dataset of the railway network in Belgium. This data set includes three classes. First class: rail network kilometer markers. Second class: railway stop. Third class: railway track segments. This dataset can be downloaded via the hyperlink in 'Access'.
