This web feature service allows viewing the NGI's historical aerial photos (1947-2007).

Mapindex is a WMS which allows viewing the regular index grid which has been defined on five levels for the entire Belgian territory. It has been defined in order to allow a zonal geolocation. The present version is a beta version (v2) which is submitted to the emergency services. It will evolve to a standard cartographic grid.

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

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.

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.

The contour lines are the set of lines connecting all points at the same elevation in a model used to represent the relief on a large scale.

CadGIS Viewer is an application developed by the General Administration of Patrimonial Documentation of the FPS Finance. This application allows to: - consult the current situation of the land register plan and the administrative units and print them out; - consult all the tax situations since 2018 (situation as on 1 January) for the land register plan and administrative units; - search and geolocate the objects on the land register plan on the basis of space characteristics or queries; - ask for and print out cadastral plan parcels within a certain range around or adjacent to one or more parcels ; - search graphically on the map for surveyors' plans (only for surveyors); - add additional data to the map, both from a predefined list (IGN - Belgian national geographical institute’s aerial photographs, Cartoweb, regional reference frames such as GRB and PICC, ...) as well as other data via the URL of web services.
