Top10Vector - Road network is the vector data set of the Belgian road network. It contains five classes. First class: dirt roads. Second class: kilometer markers along the road network. Third class: path segments. Fourth class: road obstructions. Fifth class: road segments. This data set aimt at representing the surface area of the road network on the Belgian territory and is not designed for route calculations. This data set can be bought via the corresponding hyperlink.

Top10Vector – Rail network is the data set of the railway network in Belgium. This data set includes three classes. First class: rail network kilometre markers. Second class: railway stop. Third class: railway track segments. This data set can be bought via the corresponding hyperlink.

Vector dataset of aeronautical obstacles with a height of 60 meters or more above the ground. The update of this dataset takes place on a multi-year cycle; for each obstacle and for each location, the situation is indicated as applicable at the time of its last update. Based on the horizontal range of an obstacle, it is classified into one of three classes: polygonal obstacle if the smallest rectangular area enclosing the obstacle has a length and width of more than 100 meters; line obstacle if the smallest rectangular area enclosing the obstacle has a length of more than 100 meters, but a width of less than 100 meters; point obstruction in other cases.

The eTOD digital terrain model (DTM) is a homogeneous and regular point grid indicating the elevation of the ground level in order to make a model of its surface. This DTM is obtained by resampling raw altimetric source data from the Flemish and Walloon Regions, grouped in Lambert 72 and with a resolution of 1 m; as well as data obtained internally by direct photogrammetric recording of structure points and lines based on the most recent aerial photographs for all areas not covered by regional data. For this DTM, the resolution and coordinate reference system are used as defined by the eTOD specifications.

Landcover100Map is a digital version of the NGI’s topographic cartography on a scale of 1 :100 000. The images come from the symbolisation of the objects and the themes in the topo-geographic inventory of the Belgian territory (ITGI), which is built and kept up-to-date by the NGI. Landcover100Map is meant for a regional use on a larger scale than the one for Top50Map, typically on the scale of a province. The land use theme is very salient in this topographic cartography. The relief is represented by shadowing.

The entities included in the dataset represent the Belgian road transport network in the sense of the Inspire European directive. The dataset comprises several classes. The RoadLink class represents, in a linear manner, all of the road links between each pair of dots for the network considered. The footpaths, cycle paths or carriageways that connect the pairs of dots correspond to as many entities in the class. The RoadServiceArea class represents the sections of space devoted to auxiliary road transport functions, such as service stations or rest areas. In addition to this are two classes without geometry. RoadWidth class describes in metres the width of each segment of the "road links" class. The "functional importance" class ranks the segments of the "road links" class by functional importance on the road transport network.

The entities included in the dataset represent the Belgian rail transport network in the sense of the Inspire European directive. The dataset comprises several classes and is in accordance with the INSPIRE specifications. The RailLink class represents, in a linear manner, all of the rail links between each pair of dots for the network considered. The RailwayStationNode class represents occasionally all of the stations located along the network. In addition to this are two classes without geometry. The RailwatType class ranks the segments according to the type of rail transport for which they were designed. All the segments for this dataset belong to the train category. The "RailwaytElectrification" class lists the segments according to whether they are electrified or not.

Top50Map is a digital version of the NGI’s topographic cartography on a scale of 1:50 000. The images come from the symbolisation of the objects and the themes in the topo-geographic inventory of the Belgian territory (ITGI), which is built and kept up-to-date by the NGI. It can be used for on-screen viewing or printed on scales between 1:25 000 and 1:50 000 (recommended threshold values). Top50Map is meant for regional use.

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.
