Belgium-Walloon Elevation Models

Coverage of the 5m and 25m DTM for Walloon Region, Belgium. Credit: Contains elevation data from the Service public de Wallonie (SPW) - Relief de la Wallonie, Modèle Numérique de Terrain (MNT) 2013-2014

Introduction

The Belgium-Walloon 5m and 25m elevation models (Relief de la Wallonie, Modèle Numérique de Terrain (MNT) 2013-2014) are digital terrain models (DTM) produced by EMD from 1m gridded data released by the "Service public de Wallonie (SPW)". The elevation data with windPRO is in either 5m x 5m grid or a 25m x 25m grid - and have a spatial coverage for the whole of the Walloon region. The DTM models were produced by LIDAR surveys in years 2013-2014 with 0.78-0.96 scanning points per square meter. The 5m and 25m datasets made available by EMD represents the data status of February 2020.
