RADQPE provides high resolution radar-based quantitative precipitation estimation in realtime for Belgium and its surroundings. This product is not publically available yet.

Daily forecasts for each Belgian commune, from current day up to the next 14 days. Available parameters are : min temperature, max temperature, weather type, wind speed, wind direction, maximum hust speed, quantity of precipitation. This product is not publicly available.

The ceilometer CL51 employs a pulsed diode laser LIDAR technology, where short, powerful laser pulses are sent out in a vertical or near-vertical direction. The reflection of light (backscatter) caused by clouds, precipitation or other obscuration is analysed and used to determine the cloud base height, the cloud layer height and the amount of clouds (in octas) in different layers.

Bird density profiles are derived from weather radar volume data in real time, by the vol2bird algorithm as described in Dokter et al. (2011, 2019). The vol2bird algorithm exploits the radar reflectivity characteristics of different scatterers in the atmosphere, in order to distinguish biological from non-biological radar echoes. Once biological scatterers are isolated in the volume files, the reflectivity of these scatterers is converted in an estimate of the bird density per vertical layer of 200m, using a mean cross section of 11 cm2. The vbird profiles are provided for the following radars, with the radar owner in parentheses: Jabbeke (RMI), Wideumont (RMI), Helchteren (VMM), Zaventem (Skeyes), Herwijnen (KNMI), Den Helder (KNMI), Neuheilenbach (DWD), Essen (DWD), Abbeville (Météo-France) and Avesnois (Météo-France).

Polar volume reflectivity data from the Wideumont weather radar. Volume data files are produced every 5 minutes from a multiple elevation scan. This product is not publicly available yet.

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.

Land register plan - current situation 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 current situation at the time of consultation. It is composed of fourteen geometric layers. The first five are the administrative units, namely the country, the regions, the provinces, the districts and the municipalities. The sixth and seventh layers correspond to the cadastral units, divisions and sections. the eighth layer includes the cadastral blocks, the ninth, the property stones, the tenth, the addresses, the eleventh, the polders and wateringues, the twelfth, the cadastral plan parcels, the thirteenth the buildings managed by the AGDP, and the fourteenth, buildings managed by the regions. The dataset is freely downloadable via the ad hoc WFS.

Administrative units - current situation corresponds to the dataset of administrative units from the reference database for the land register data. Administrative limits are legally defined by an administrative entity or between two administrative entities. In Belgium, administrative limits as legally defined are fixed and can only be changed by a law, ordinance or decree. The General Administration of Patrimonial Documentation of the FPS Finance is named by the federal authorities as the authentic source of Belgian administrative limits. This dataset corresponds to the current situation at the time of consultation. It is composed of five geometric classes. The first class corresponds to the whole national territory. The second corresponds to the territory of the three regions, the third to the territory of the provinces, the fourth to the territory of the administrative districts, the fifth to the territory of the municipalities. The dataset is freely downloadable via the ad hoc WFS service.
