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.

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.

Landcover100Map is a digital version of the NGI’s topographic cartography on a scale of 1 :100 000. The images come from the symbolisation of the objects and the themes in the topo-geographic inventory of the Belgian territory (ITGI), which is built and kept up-to-date by the NGI. Landcover100Map is meant for a regional use on a larger scale than the one for Top50Map, typically on the scale of a province. The land use theme is very salient in this topographic cartography. The relief is represented by shadowing.

Orthophotographs are digital aerial photographs that have been adjusted for lens distortion, topographic relief and camera tilt. The orthophotographs are metrically more accurate than common aerial photographs. They are very valuable as reference information and also, for instance, for surveying parcels. This cover is renewed every year by the regions. The orthophotographs are produced on the basis of digital colour aerial photography. The orthophotographs have a minimal resolution of 25 cm. A mosaic of the orthophotos can be consulted on the map viewer or via the viewservices.

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 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.

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 present target year 1975, which corresponds to the middle of the 30-year period 1961-1990.

AdminMap is the digital version of the administrative map. Two versions exist: the most complete one on the scale of 1:300 000 and a simplified version on the scale of 1:500 000. These maps show the different administrative units on the Belgian territory, from the federal State to the center of the districts for the 1:500 000. The map also shows the map grid of the National Geographic Institute. An index allows localizing the different units. The index also contains information on the linguistic statutes and on the postal codes.

Top50Map is a digital version of the NGI’s topographic cartography on a scale of 1:50 000. The images come from the symbolisation of the objects and the themes in the topo-geographic inventory of the Belgian territory (ITGI), which is built and kept up-to-date by the NGI. It can be used for on-screen viewing or printed on scales between 1:25 000 and 1:50 000 (recommended threshold values). Top50Map is meant for regional use.

Orthophotos are digital aerial photographs that have been adjusted for lens distortion, topographic relief and camera tilt. This cover is renewed every three years.The orthophotographs have a minimal resolution of 50 cm. The dataset is generated from the harmonisation of the datasets owned by the Belgian administrative regions.The dataset is INSPIRE compliant. The dataset is downloadable per NGI mapsheet at scale 1:50000.

Top250Map is a digital version of the NGI’s topographic cartography on a scale of 1:250 000. It is the smallest scale used by the NGI to produce a cartographic representation of Belgium. It focuses mainly on inhabited places and transport networks. The whole territory is available in one single file. This map is characterized by the great number of toponyms of inhabited places.
