Belgium-Flemish Elevation Models

Part of the 1m DTM for Flanders, Belgium.

Introduction

The Belgium/Flanders 5m and 25m elevation models (Digitaal Hoogtemodel Vlaanderen II) are digital terrain models (DTM) produced by the Agency of Geographical Information Flanders (Agentschap voor Geografische Informatie Vlaanderen). 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 Flanders region. The DTM models were produced by LIDAR surveys in years 2013-2015 with 16 scanning points per square meter.

Acurracy for the LIDAR data is: Horizontal (XY): 0.10m and vertical (Z): 0.05m

Availability from within WindPRO

The data are available directly from within windPRO in 5m and 25-meter resolution. The data can be accessed from the online-services in the following objects:

• Line Object (with purpose to height contour lines)
• Elevation Grid Object

Usage Notes

Please consider the following, when using the data as contour-lines in windPRO:

• You may need to digitize the coastline (0m - contour) - as the grid-cells in the sea/ocean may be attributed with a 'no-data' value

Reference System

The following reference systems were used in the original data:

• Horizontal: Belgian Lambert 1972 (EPSG 31370)
• Vertical: Second General Levelling (TAW, EPSG: 5710)
