The number of private households according to official statistics, per administrative unit (region, province, district and municipality) for Wallonia.

The number of inhabitants according to official statistics by age group (<20 years, >=65 years, >=80 years) and by administrative entity (region, province, district and municipality) for Wallonia.

Summer and winter mean wind speed given in m/s. The wind speed fields 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 service makes it possible to view the aerial photos with orthorectification taken by Hansa Luftbild at NGI's request following the floods of July 2021 in the areas of the Vesdre, part of the Meuse downstream of Liège and the Demer. The resolution of the original data is 6.5 cm (4 cm above the Hoëgne). The service allows the images to be viewed at a maximum resolution of 25 cm. Orthophotos are digital aerial photographs in which the systematic distortions due to the central projection, relief and the not always perfectly vertical axis of shooting have been corrected. The orthophoto thereby obtained is metrically more accurate than an ordinary aerial photograph and is highly valuable as basic information.

The Royal Decree of 22 May 2019 establishing a marine spatial plan defines 11 military use and storage sites for war munition zones: Exercise area for sweeping mines (Buiten Ratel) (Art. 17§1), Exercise area for sweeping mines - NB-01 (Westhinder) (Art. 17§1), Exercise area for sweeping mines - NBH-10 (Wenduine) (Art. 17§1), Exercise area for sweeping mines - QZR 040 (Art. 17§1), Munition destruction area (Art. 17§2), Area for shooting exercises on floating objects (Art. 17§3), Area for exercises in shallow waters (Art. 17§4), Area for shooting exercises from land - big sector (Art. 17§5), Area for shooting exercises from land - medium sector (Art. 17§5), Area for shooting exercises from land - small sector (Art. 17§5), Storage site for war munition Paardenmarkt (Art. 18§1). It replaces the 2014 Marine Spatial Plan, which is included for completeness. The Royal Decree of 20 March 2014 establishing a marine spatial plan defines in its Art. 13. and Art. 14., resp. nine zones for military use and one storage site for war munition: three zones for shooting exercises from land direction sea (Art 13. § 1 small sector, Art 13. § 1 medium sector, Art 13. § 1 large sector), four exercise areas for sweeping mines (Art 13. § 3, Exercise area 1 for sweeping mines, Art 13. § 5, Exercise area 2 for sweeping mines, Art 13. § 9, Exercise area 3 for sweeping mines, Art 13. § 13, Exercise area 4 for sweeping mines), one area for shooting exercises on floating objects (Art 13. § 7), one area for defusing mines (Art 13. § 11) and one zone to safeguard the closed storage site for war munition \"Paardenmarkt\" (Art. 14. § 1). These zones are made available digitally in the resource described by this metadata document. Please refer to the Belgian official gazette (\"Moniteur belge/Belgisch Staatsblad\") for official reference information.

Annual temperature extremes given in number of days: 1/ Total number of heatwaves occurring once in 20 years; 2/ Maximum length of the heatwaves occurring once in 20 years; 3/ Hot days: Mean annual number of days with maximum temperature > 25°C; 4/ Tropical days: Mean annual number of days with maximum temperature > 30°C; 5/ Frost days: Mean annual number of days with minimum temperature < 0°C. Heatwaves are defined according to the Royal Meteorological Institute of Belgium when the maximum temperature in Uccle is >= 25°C during at least 5 consecutive days, during which at least 3 days the maximum temperature is >= 30°C. The temperature extremes are available for the present target year 1975, which corresponds to the middle of the 30-year period 1961-1990.

Annual, summer and winter mean potential evapotranspiration given in respectively mm/year and mm/3 months and based on the Penman-Monteith definition. The potential evapotranspiration fields are available for the present target year 1975, which corresponds to the middle of the 30-year period 1961-1990.

Summer and winter mean relative humidity given in %. The relative humidity fields 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 percentiles of the change factors.

Summer and winter mean wind speed given in m/s. The wind speed fields are available for the present target year 1975, which corresponds to the middle of the 30-year period 1961-1990.

This dataset shows a digital surface model. It is a homogeneous and regular points grid which indicates the height above the surface of the earth, either the soil or any other permanent and visible element in the landscape (vegetation, construction,…). These data represent the situation of the landscape resulting from the July 2021 floods in het areas of the Vesdre, of part of the Meuse downstream from Liège and of the Demer.
