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.

The "Aeronautical Obstacle Evaluation Map for Belgium" allows to know whether advice is required for a construction or structure that, due to its height, may have an influence on aviation: if the planned construction or structure exceeds the height indicated on the map, the Civil Aviation Authority of the Federal Public Service Mobility and Transport should be requested for advice, according to the procedure on https://mobilit.belgium.be/nl/luchtvaart/veiligheid/hindernissen-en-bebakening. The height indicated on the map is determined by the federal ministers responsible for Civil Aviation and Defence. This height is determined in order to protect the civil and military aerodromes, the visual aviation routes, the military aviation areas and the civil and military aeronautical installations for communication, navigation and surveillance (CNS). Consequently, the use of this map allows the application of the following Regulation : Regulation (EC) N° 1108/2009 of the European Parliament and of the Council of 21 October 2009 amending Regulation (EC) No 216/2008 in the field of aerodromes, air traffic management and air navigation services and repealing Directive 2006/23/EC. In the Flemish Region the use of this chart allows the application of the article 35 §16 of “het besluit van de Vlaamse Regering van 27 november 2015 tot uitvoering van het decreet van 25 april 2014 betreffende de omgevingsvergunning”. The same data limited to the flemish Region are available on the Digitaal Vlaanderen website.

Settlement area is defined here in terms of land use. Settelement area is the space occupy to live, work, relax and move around. This includes everything that seals the soil but also includes various forms of non-paved green space, such as gardens and parks or sports grounds and these are therefore not counted as open space. These indicators show the total settelement area expressed in m² and the part of the settlement area in relation to the total area per administrative entity (region, province, district and municipality) for Flanders.
