Top10Vector – Hydrography is the data set of the Belgian hydrography. This data set includes six classes. First class: waterway kilometre markers of the Belgian navigable waterways. Second class: watercourse surfaces. Third class: watercourse segments. Fourth class: water points, which means points where the water arrives at the surface or disappears into the subsoil. Fifth class: wetlands, which means zones where the soil is saturated or regularly flooded. Sixth class: water surfaces. This data set can be bought via the corresponding hyperlink.

The entities included in the dataset represent the Belgian hydrographic network in the sense of the Inspire European directive. The dataset comprises one sole WaterCourseLink class and is in accordance with the INSPIRE specifications. The WaterwayLink class represents, in a linear manner, all of the waterways in the Belgian hydrographic network.

The entities included in the dataset represent the physical network in the sense of the Inspire European directive. The dataset comprises several classes and is in accordance with the INSPIRE specifications. The Wetland class represents poorly drained or periodically flooded portions of land, the soil of which is saturated with water but where vegetation is nevertheless able to develop. The StandingWater class represents flooded areas that are, nevertheless, completely surrounded by land.

The entities included in dataset represent the Belgian waterway transport network in the sense of the Inspire European directive. The dataset comprises several classes and is in accordance with the INSPIRE specifications. The class represents, in a linear manner, all of the waterway links between each pair of dots for the network considered. In addition to this is one class without geometry. The RestrictionForWaterCehicles class specifies for each segment the maximum tonnage of the building using the segment.
