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).

RADCLIM is derived from weather-radar reflectivity measurements by RMI software (RMIRADLIB2). The processing uses 3D reflectivity measurements from the radars in Wideumont and Jabbeke (RMI, Belgium), Helchteren (VMM, Belgium) and Avesnois (Météo-France, France), together with automatic rain-gauge observations from the Service Public de Wallonie (SPW), Vlaamse Milieumaatschappij (VMM), and Waterbouwkundig Laboratorium / Hydrologisch Informatiecentrum (WL/HIC) networks and provides gridded precipitation accumulations of 5 minutes and 1 hour. The 1-hour accumulation product is computed by summing consecutive 5-minute precipitation estimates. The processing chain includes quality control of radar measurements, including handling of permanent contamination and beam blockage, as well as clutter identification using satellite cloudiness products, vertical profiles of reflectivity and image texture. Radar reflectivity is then converted to ground rainfall rate, missing data are interpolated, and radar information is merged into a composite product. Gauge information is incorporated through mean field bias correction and External Drift Kriging (EDK).
Share of the cadastral land take - Wallonia
Share of the cadastral surface area that is artificially developed in the cadastral surface area and not unknown to the administrative entity (region, province, district and municipality) for Wallonia

The land use and land cover data used by IWEPS for Wallonia are taken from the Belgian Cadastre (SPF Finance). A cadastral parcel includes the buildings, annexes, outbuildings, accesses and gardens that are contiguous to it, provided that the whole forms an indivisible whole and is assigned to the same use (SPF Finance, 2014). For each cadastral parcel, the surface area and the cadastral nature are available. The latter corresponds to the main use of the parcel at the time of its last cadastral registration (e.g. house, farm, business, etc.). In 2008, a land use nomenclature was developed on the basis of a joint reflection by the standing conference on territorial development, the SPW Environment and the IWEPS. The cadastral natures were grouped into 16 land use categories. These 16 categories can be grouped together to distinguish between artificial and non-artificial land. This grouping of parcels is based on the work of the European CORINE Land Cover (CLC) project in order to facilitate comparisons with other European regions. The land registry data are not exhaustive. In 2021, 5.2% of Wallonia's territory is not registered and/or of unknown nature. The unregistered areas are part of the public space (roads, squares, railways, rivers and canals, etc.). These areas of unknown nature are not homogeneously distributed over the Walloon territory. The proportion of unknown areas varies from 2% (larger or rural municipalities) to over 20% (Liège and Visé). The Sambre-et-Meuse region accounts for a large proportion of this area.
A climate normal is an average over a 30-years period. The period 1981-2010 is the current reference period recommended by the World Meteorological Organization (WMO). Recent climate normals are available for any locations in Belgium and several parameters including air temperature, precipitations and solar radiation. Climate normals for the reference period 1981-2010 are available for air temperature, precipitation and derived parameters (e.g., annual number of summer days, annual number of precipitation days, etc.). For solar radiation, the reference period had to be adjusted to 1984-2013 because of data availability. These climate normals are available as maps and as table for each Belgian municipality.
The climate statistics are derived from 30-years long observations timeseries in Belgium spatially interpolated on the Belgian territory.
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.
Hail detection module is an implementation of two hail detection algorithms: of Witt and of Waldvogel (Waldvogelet al., 1979). The module takes radar observations and temperature information and estimates probability of hail (POH, %), probability of severe hail (POSH, %) and maximum expected size of hail (MESH, mm). The implementation of the Waldvogel algorithm is based on the Holleman's equation (I. Holleman, 2001), which was verified for Belgium by Delobbe et al. (2003). The POH is derived in the algorithm from the presence of a substantial updraft detected above the freezing level (0º-isoterm). The implementation of the Witt algorithm is based on the weighted integration of the reflectivity values between the heights of 0º-isoterm and -20º-isotherm (Witt et al., 1998). This algorithm provides POSH and MESH estimates.
Govroam is a " wifi roaming " solution. This service offers to the users a simple and secure access to the wireless network of their institution, but also to networks of other participating institutions. A user from an organization that participates in govroam will be able to connect to any wireless access point broadcasting govroam. The data provided here makes it possible to locate these access points.
The map shows the location of Wi-Fi access points that broadcast govroam. This list is established on the basis of the information provided by the administrators of these access points (address of the building, local, ...). It is subject to change depending on the installation / uninstallation of new access points.
Statistical sectors in Belgium (INSPIRE version)
The data set has been established according to the INSPIRE format. It presents in the form of polygons the breakdown of Belgium in almost 20,000 statistical sectors. The statistical sector is the basic territorial unit resulting from the subdivision of the territory of municipalities by STATBEL since 1970 for the dissemination of its statistics at a finer level than the municipal level. A statistical sector cannot extend over two municipalities and any point in the municipal territory is part of one and the same statistical sector. The 1970 and 1981 versions are shown in analogue format while the 2001, 2011, 2018, 2019 etc. versions are available in digital vector format. The files can be linked to the data on population, housing and disposable income on the website of Statbel.

The data set ‘Statistical sectors in Belgium (INSPIRE version)’ is derived from the data set ‘Statistical sectors in Belgium (native version)’. The statistical sectors were created based on social, economic, urbanistic or morphological characteristics as part of the population and housing census from 1970. They were outlined and represented on analogue topographic 1:10,000 maps. Since then, they were updated several times: • the general population and housing census from 1981: to take into account the increase in settlement clusters, new infrastructure works as well as the new administrative borders due to the merger of municipalities carried out since the 1970 census; • the general population and housing census from 1991: to integrate the new administrative borders from the merger of municipalities in Antwerp; • the socio-economic survey from 2001: to take into account the exchange of territories among municipalities, the increase in settlement clusters and employment zones as well as the new infrastructure works such as the TGV railway line; • the population and housing census from 2011: to integrate the new municipal borders from an exchange of territories between two municipalities (Seneffe and Manage in the province of Hainaut) ; • in 2018: to integrate an exchange of territories between Belgium and the Netherlands and to include the intertidal zone in the territory of the municipalities bordering the North Sea and the new version of the administrative borders published by the General Administration of the Patrimonial Documentation; • since 2019, the borders of statistical sectors are reviewed annually based on the municipal borders provided by the General Administration of the Patrimonial Documentation in order to take into account their evolutions and geometric corrections. The digital versions available are derived from the vectorisation of analogue 1:10,000 maps from 1981 referenced in the CRS EPSG 31370 (Belgian Lambert 72) by means of electronic tables to be digitized. The 2001 version is built from a general version (1:10,000) of the administrative borders provided by the National Geographic Institute (NGI), while the following versions are based on more precise versions provided by the General Administration of the Patrimonial Documentation.
This dataset comprises historical orthophotos from the 1980s to 1989, derived from aerial surveys carried out by the National Geographic Institute (NGI). The ground sample distance (GSD) of the images is 10 cm. The mosaics were created using aerial photography campaigns dating from 1989. The original photographs were digitised and orthorectified in the Lambert 2008 coordinate system. The spatial coverage for each year corresponds to the areas for which photographs were available. High-resolution data can be ordered via https://shop.ngi.be/fr/photos-aeriennes/

Foreign real estate - Property characteristics
Foreign real estate - Property characteristics corresponds to the dataset of foreign real estate held by belgian taxpayers as declared to the FPS Finance (only the holders of rights allowing the enjoyment of the property are taken into account). This dataset consists of one class. This class includes, for each foreign country or territory, the number of properties in each category, the total cadastral income of these properties, the median cadastral income of each category, as well as the 25 and 75 percentiles of the cadastral income of each category.
The licence is fully available in French (https://finances.belgium.be/sites/default/files/Licence_plan_opendata_FR.PDF) or in Dutch (https://financien.belgium.be/sites/default/files/Licentie_plan_opendata_NL.PDF).
Foreign real estate - Property characteristics is based on the database of foreign cadastral income. This database contains the data declared by Belgian taxpayers holding real rights on real estate located abroad. On the basis of the data declared, the FPS Finance sets a cadastral income for each property abroad.
