Bathymetry - Altitude of the waterbed of Walloon waterways
Description
Topography of the bottom of waterways and reservoir dams in the Walloon Region.
This raster data layer presents the results from the bathymetry of waterways in the Walloon Region as well as reservoir dams. This method makes it possible to know the depth of the different rivers surveyed. The pixel value is the altitude expressed in mDNG .
The resolution is 50cm and the accuracy is less than 10cm in all 3 directions.
This is a composite image obtained by integrating different surveys carried out over a period of approximately 4 years. The majority of the surveys were done between 2019-2023
Particular attention needs to be paid to the fact that the topography of waterways is constantly changing. The bathymetric data is therefore the picture of the situation at the time of the survey itself. Consequently, this data is only disseminated for information purposes and can only be interpreted as it stands in any use under the sole responsibility of the user.
