  • This dataset shows a digital surface model. It is a homogeneous and regular points grid which indicates the height above the surface of the earth, either the soil or any other permanent and visible element in the landscape (vegetation, construction,…). These data represent the situation of the landscape resulting from the July 2021 floods in het areas of the Vesdre, of part of the Meuse downstream from Liège and of the Demer.

  • Network of marks whose planimetric coordinates are known with precision according to the reference systems which are used in Belgium.

  • This dataset contains the orthophotos of the floodable areas along the Meuse, the Vesdre and the Demer. These orthophotos are digital aerial photographs, taken by Hansa Luftbild following the floods of July 2021, in which the systematic distortions due to the central projection, relief and the not always perfectly vertical axis of shooting have been corrected. The orthophoto thereby obtained is metrically more accurate than an ordinary aerial photograph and is highly valuable as basic information. The resolution of the data is 6.5 cm (4 cm above the Hoëgne).

  • Landuse-Particular Zone is the INSPIRE 2D vector data set of the "Particular zones" layer originated from the Top10vector product of the National Geographic Institute in Belgium . It includes the "ExistingLandUseDataSet" features and the "ExistingLandUseObject" features in accordance with the INSPIRE specifications.

  • The layer Geographical Names includes all the names of administrative units, uninhabited places, waterways, remarkable buildings and infrastructures. They are classified into different feature and attribute classes.

  • Buildings is the INSPIRE 2D vector data set of the "Constructions" layer originated from the Top10vector product of the National Geographic Institute in Belgium . It includes the "Building" features and the "OtherConstruction" features in accordance with the INSPIRE specifications.

  • The service makes it possible to view the aerial photos with orthorectification taken by Hansa Luftbild at NGI's request following the floods of July 2021 in the areas of the Vesdre, part of the Meuse downstream of Liège and the Demer. The resolution of the original data is 6.5 cm (4 cm above the Hoëgne). The service allows the images to be viewed at a maximum resolution of 25 cm. Orthophotos are digital aerial photographs in which the systematic distortions due to the central projection, relief and the not always perfectly vertical axis of shooting have been corrected. The orthophoto thereby obtained is metrically more accurate than an ordinary aerial photograph and is highly valuable as basic information.

  • The INSPIRE contour lines used for a cartographic representation of the relief at scale 1:50000, a product of the National Geographic Institute in Belgium. The dataset features are in accordance with the INSPIRE specifications.

  • Orthophotos are digital aerial photographs that have been adjusted for lens distortion, topographic relief and camera tilt. This cover is renewed every three years.The orthophotographs have a minimal resolution of 50 cm. The dataset is generated from the harmonisation of the datasets owned by the Belgian administrative regions.The dataset is INSPIRE compliant. The dataset is downloadable per NGI mapsheet at scale 1:50000.

  • 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.
