RADCLIM is a historical dataset based on weather radar observations that provides gridded accumulated precipitation composites over Belgium and surrounding regions. The data are distributed in ODIM_H5 version 2.2 format. The reported quantity is accumulated precipitation (ACRR) for 5-minute and 1-hour accumulation periods. UTC is used as the time reference, and the timestamp in the filename corresponds to the end of the accumulation period. The dataset is produced on a 700 × 700 grid with 1 km spatial resolution in the Belgian Lambert 2008 projection (Lambert Conformal Conic).

The files contain the population characteristics (total, gender and/or age groups) by statistical sector in Belgium on January 1st, according to the Belgian definition of the population. The Belgian definition does not take into account the 12-months criterion and excludes asylum seekers.

Summer and winter maximum daily precipitation given in mm/day that occur once in a year and once in 5, 10, 15 and 30 years (i.e. return periods of 1 year and 5, 10, 15, 30 years). The precipitation extremes are available for the future target year 2085, which corresponds to the middle of the 30-year period 2071-2100, and for mean and high impact scenarios corresponding respectively to the 50th and 95th percentiles of the change factors.

The average household size of private households, by administrative unit (region, province, arrondissement and municipality) for Flanders

Cadastral parcels - monthly situation corresponds to the dataset of the monthly situation of the cadastral parcels layer from the Land Register plan. The dataset is composed of two classes. The first class contains the geometries of the cadastral parcels; the second is a class without geometry and corresponds to a code table of the different fiscal situations used in the first class. The dataset can be freely downloaded as a zipped shapefiles.

The national wastewater-based epidemiological surveillance of respiratory syncytial virus (RSV) monitors the RSV presence in several wastewater treatment plants across Belgium. This dataset contains the results per treatment plant since the beginning of the surveillance in January 2024. The results consist of the RSV concentrations over time as well as other data needed for the interpretations such as the flow rates of the treatment plants and the population covered.

Annual and seasonal precipitation indices given in number of days: 1/ Wet days: Number of days with precipitation > 0.1 mm/day for winter, autumn, spring, summer; 2/ Dry days: Number of days with precipitation < 0.1 mm/day for winter, autumn, spring, summer; 3/ Average length of dry spells: Mean duration of minimum three consecutive days with precipitation < 0.1 mm/day; 4/ Maximum length of dry spells: Longest period of minimum three consecutive days with precipitation < 0.1 mm/day, occurring once in 20 years. The precipitation indices are available for the future target year 2085, which corresponds to the middle of the 30-year period 2071-2100, and for mean and high impact scenarios corresponding respectively to the 50th, and 5th or 95th percentiles of the change factors.

Top10Vector – High tension network is the vector dataset of the high tension network in Belgium. The dataset consists of two classes. The first class contains the high-voltage segments and the second class contains the high-voltage pylons. This dataset can be downloaded via the link in 'Access'.

Orthophotos are aerial photographs that have been geometrically corrected (orthorectified) to eliminate distortions caused by terrain relief, lens distortion, and camera tilt. Unlike raw aerial imagery, orthophotos have a uniform scale and accurate geometry, making them suitable for cartography, measurements, and visual analysis. This specific dataset includes historical orthophotos from 1947 and 1948, derived from aerial surveys carried out by the National Geographic Institute (NGI). During this period, only analogue aerial photographs are available. The analogue images were scanned at high resolution and orthorectified. The resulting orthophotos were assembled into mosaics and georeferenced in the Lambert 2008 coordinate system. All orthophotos are panchromatic (black and white). The ground resolution (GSD) is 50 cm.

Land register plan - situation on January 1st corresponds to the dataset of land register from the reference database for the land register data CadGIS. The land register plan is one of the elements that make up the patrimonial documentation. It is defined as “the graphic representation and assembling on a plan of all the cadastral plan parcels of the Belgian territory”. A plan parcel, such as defined in Article 2 of the Royal Decree of 30 July 2018, is a part of Belgian territory, geographically delimited and identified by the General Administration of Patrimonial Documentation on the land register plan, which corresponds to the ground surface area of one or more patrimonial cadastral parcel(s) (real estate property as mentioned in Article 472 of the 1992 Income Tax Code in respect of which the cadastral income is fixed). This dataset corresponds to the legal situation as defined on 1 January of the reference year. It is composed of thirteen geometric classes and one class without geometry. The first class includes the cadastral plan parcels present in the corresponding administrative unit. The second class includes the buildings managed by the General Administration of Patrimonial Documentation, the third class includes the buildings managed by the regions, the fourth class includes equipment and tools, the fifth class includes water bodies, the sixth class includes cadastral blocks, the seventh, easements and paths, the eighth, toponymic lines, the ninth, toponymic points, the tenth, property boundaries, the eleventh, parcel numbers, the twelfth, cadastral divisions, and finally, the thirteenth, cadastral limits. The class without geometry corresponds to the table of tax situations. The dataset can be freely downloaded as a zipped shapefiles.
