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.

Notifications of the cadastral income corresponds to the dataset describing the new cadastral incomes of property located in Belgium that has been notified to the taxpayer. This dataset is made up of seven classes. The first class includes, at national level, by fiscal status, by nature of cadastral income and by category of motivations, the number of cadastral incomes notified, the total amount of cadastral incomes notified, the median cadastral income notified, the 25th and 75th percentiles of cadastral incomes notified and the standard deviation of cadastral incomes notified. The second class includes this information at the level of the three regions. The following classes do the same at the level of provinces, arrondissements, municipalities, cadastral divisions and statistical sectors. The dataset can be freely downloaded as a zipped CSV.

Real estate property dynamics corresponds to the dataset describing changes in ownership in Belgium as recorded by the FPS Finance. This dataset comprises seven classes. The first class includes, at national level, for each cadastral nature, the total number of parcels, the number of parcels that have changed ownership at different time intervals, the median and mean duration since the last change of ownership, the 25 and 75 percentiles of the duration since the last change of ownership, and the mean duration of ownership rotation over the entire existence of the parcels. The second class uses this information for all three regions. The following classes do the same for provinces, arrondissements, communes, cadastral divisions and statistical sectors. The dataset is freely downloadable as zipped CSV files.

The climate projections for Belgium are available as different data types: 1/ Daily climate model simulations and projections at a high spatial resolution of 0.025° or 2.8km for 3 Regional Climate Models (download service with NetCDF files): - ALARO-0 forced with the Global Climate Model ‘CNRM-CERFACS-CNRM-CM5’, calculated by RMIB-UGent; - COSMO-CLM5.0-TERRA-URB forced with the Global Climate model ‘ICHEC-EC-EARTH’, calculated by KULeuven; - COSMO-CLM5.0 forced with the Global Climate Model ‘MPI-M-MPI-ESM-LR’, calculated by UCLouvain. 2/ Climate indicators for a present (1975) and future (2085) target year under a mean and high impact scenario (view and download service with raster files). The climate indicators for Belgium were obtained by a statistical downscaling based on the high-resolution Belgian climate model projections, as well as on a large set of both Global Climate Model runs (CMIP5) and Regional Climate Model runs for Europe (EURO-CORDEX).

'Top10Vector – Particular Zones' is the vector dataset covering areas within Belgium that are designated for a specific purpose. This dataset contains just one feature type [ZO_particularzone]. The dataset can be downloaded via the links in 'Access' at the bottom of this page.

Hail products are derived from the observed vertical profiles of radar reflectivity and the NWP vertical profiles of temperature. Three types of products are generated. poh : probability of hail of any size (larger than 0.5 cm diameter)expressed in %. posh : probability of severe hail(larger than 2cm)expressed in %. mesh : maximum expected size of hailexpressed in mm of hailstone diameter. All products are generated every 5 minutes. This product is not publically available yet.

The Royal Decree of 20 March 2026 establishing the marine spatial plan for the period 2026 to 2034 in the Belgian marine areas defines 13 nature conservation areas: Seabed integrity zone: Zone 1, upper (Art. 10§1.1°), Seabed integrity zone: Zone 2, middle (Art. 10§1.2°), Seabed integrity zone: Zone 3, lower (Art. 10§1.3°), Ramsar area (Art. 11), Special Area of Conservation "Vlaamse Banken" (Art. 8§1), Special Area of Conservation "Vlakte van de Raan" (Art. 8§3), Special Protection Area for Birds: SPA 1 (Art. 8§5.1°), Special Protection Area for Birds: SPA 2 (Art. 8§5.2°), Special Protection Area for Birds: SPA 3 (Art. 8§5.3°), Marine reserve: Zone 1, upper (Art. 9§1.1°), Marine reserve: Zone 2a, middle (Art. 9§1.2°), Marine reserve: Zone 2b, middle (Art. 9§2), Marine reserve: Zone 3, lower (Art. 9§3). It replaces the 2020 Marine Spatial Plan. Please refer to the Belgian official gazette ("Moniteur belgeBelgisch Staatsblad") for official reference information.

This datasets is a summary of the CTD profiles measured with the RV Belgica. It provides general meta-information such as the campaign code, the date of measurement and the geographical information. An important information is the profile quality flag that describes the validity of the data. A quality flag = 2 means the data is generally good although some outliers can still be present. A quality flag = 4 means the data should not be trusted. 1 meter binned data can be download on the SeaDataNet CDI portal (enter the cruise_id in the search bar) ONLY for the good quality profiles. Full acquisition frequency datasets are available on request to BMDC.
