The product Hillshade DTM 1m is a slope shading view of the digital terrain model (DTM) at 1m resolution. The source data used to produce this Hillshade DTM 1m are the DTM at a 1m-resolution from the regions: data from Digitaal Vlaanderen (former AIV and former AGIV) for the Flemish Region, data from the SPW for the Walloon Region and data from Paradigm for the Region of Brussels-Capital. These regional DTM are derived from the clouds of points obtained during the LiDAR campaign (flight of 9 October 2021 for Brussels, from 19 February 2021 to 5 March 2022 for Wallonia and from 20 February 2013 to 20 April 2015 for Flanders). In order to create this representation, we have used the following parameters: - Azimut: 315° (angle of the fictitious light source relative to the north) - Angle: 45° (angle of the fictitious light source above the horizon) The hillshade view allows to create a graphic effect on the map which gives an idea of the relief on the terrain. LiDAR data coming from regions do not stop at borders, the coverage of the data extends beyond the limits of Belgium and offers a buffer of variable size all around Belgium.
An hillshade is a homogeneous and regular points grid, indicating the grey tone deriving from their orientation relative to the chosen fictitious light source. The Hillshade DTM 5m is a representation of the hillshading of the DTM 5m.
The product Hillshade DTM 5m is a shaded slope view based on regional elevation data compiled and updated in the form of a digital terrain model (DTM) with a 5m resolution. The source data used to produce this DTM are the DTM at a 1m-resolution from the regions: data from Digitaal Vlaanderen (former AIV and former AGIV) for the Flemish Region, data from the SPW for the Walloon Region and data from Paradigm for the Region of Brussels-Capital. These regional DSM are derived from the clouds of points obtained during the LiDAR campaign (flight of 9 October 2021 for Brussels, from 19 February 2021 to 5 March 2022 for Wallonia and from 20 February 2013 to 20 April 2015 for Flanders). The DTM 5m is improved and updated internally using direct photogrammetric surveys based on the most recent aerial photographs. The DTM 5m consists of a compilation of the best available data, and these are constantly updated and improved. To create this representation, we have used the following parameters: - Azimut: 315° (angle of the fictitious light source relative to the north) - Angle: 45° (angle of the fictitious light source above the horizon) Slope shading views allow the creation of a graphic shading effect that gives an idea of the terrain relief on cartographic representations. LiDAR data coming from regions do not stop at borders, the coverage of the data extends beyond the limits of Belgium and offers a buffer of variable size all around Belgium.
This view service allows visualization of the Hillshade DTM1m, the shaded version of the digital terrain model at a resolution of 1m.

The DTM 5m, digital terrain model at 5m-resolution, is a homogeneous and regular point grid indicating the height of the ground level in order to model its surface, without taking into account objects on the surface such as buildings and vegetation. The DTM 5m is the result of the assembly of different data coming from various sources and with different coordinate systems and resolutions. The DTM 1m is achieved by interpolating in Lambert 2008 source data in Lambert 72 and at a 1m-resolution from the Flemish (2013-2015) and Brussels (2021) regions, and by adding Lambert 2008 data at 1m-resolution from the Walloon Region (2021-2022). The DTM 5m is obtained by resampling of the DTM 1m. In addition, the DTM 5m is improved and updated internally using direct photogrammetric surveys based on the most recent aerial photographs.
The product called DTM 5m indicates the height of the ground compared to the Belgian zero level (fictitious zero-D of Uccle). In other words, it is the orthometric height, commonly known as height. The source data used to produce this DTM are the DTM at a 1m-resolution from the regions: data from Digitaal Vlaanderen (former AIV and former AGIV) for the Flemish Region, data from the SPW for the Walloon Region and data from Paradigm for the Region of Brussels-Capital. These regional DSM are derived from the clouds of points obtained during the LiDAR campaign (flight of 9 October 2021 for Brussels, from 19 February 2021 to 5 March 2022 for Wallonia and from 20 February 2013 to 20 April 2015 for Flanders). As the Flemish and Brussels regional bodies deliver their products in Lambert 72, the NGI reprojected those in Lambert 2008 and achieved an interpolation in order to obtain a product with round coordinates, and then gathered them with the product of the Walloon Region (already in Lambert 2008) so that the newly created DTM covers the whole Belgian territory. These source data are gathered and processed in order to obtain a homogeneous and regular grid with every meter a point in X and Y indicating the height of the ground level. This grid makes the product DTM 1m. This product comes directly from the regional data and is not updated. The DTM 1m is resampled by bilinear interpolation in order to obtain the same type of grid at a 5m-resolution. This is also improved and updated in-house using direct photogrammetric surveys of points and structure lines based on the most recent aerial photographs in order to create the product DTM 5m. The DTM 5m consists of a compilation of the best available data, and these are constantly updated and improved. LiDAR data coming from regions do not stop at borders, the coverage of the data extends beyond the limits of Belgium and offers a buffer of variable size all around Belgium.
Hourly forecasts for each belgian commune, from current hour up to the next 5 days. This product is not publically available.
RMI forecasters analyze all the available numeric models and choose those reflecting the situation in Belgium best. These model forecasts are then corrected by the forecasters themselves. Monthly statistics are generated to evaluate the quality of the model data and the accuracy of the corrections applied by the forecasters.

The composite is produced every 5 minutes using the reflectivity data from the Wideumont and Jabbeke weather radars. This product is not publicly available yet.
The rainfall composite combines 2D products from the Wideumont, Jabbeke and Zaventem weather radars. Reflectivity values are converted into rainrates using the Marshall-Palmer relation. For each pixel, the maximum value of the three products is taken. The effective coverage of the composite is smaller than the bounding box. It is determined by the maximum ranges of the three radars, i.e. 250 km for Wideumont, 300 km for Jabbeke, and 250 km for Zaventem.
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.
