Part of the 10m DTM for Iseland. Credit: Contains elevation data from the National Land Survey of Iceland.

Introduction

Iceland LMI Elevation Model 2016 - 10m resolution (LMÍ Hæðarlíkan 2016): The National Land Survey of Iceland has released a DTM of Iceland - covering the whole country: This new DTM is an upgrade of an earlier DTM. The recent data added, which vary in origin, cover 39.100 km2 or some 38% of the country.

Dataset Overview

  • Spatial Coverage: Iceland
  • Reesolution: 10m
  • Data type: Digital Terrain Model (DTM)
  • Coordinate System: ISN93 / Lambert (EPSG:3057)
  • Version: 2016 (with data acessed in spring 2022)
  • Vertical accuracy: Varies, see image to the right and usage notes below

Usage Notes

  • An alternativetive Icelandic elevation model (IcelandDEM version 1.0) is available from the icelandic
  • The vertical accuracy of the new (2016) data added are (see location on figure to the right): 1) Lidar data for the glaciers of Iceland (surveyed in the years 2007-2012), 15144 km2, LE90: 2.65 m. 2) Data from 5-m-contour lines, 10736 km2, LE90: 3.9 m. 3) Emisar radar data, 4536 km2, LE90: 3.2 m. 4) Data from 10-m-contour lines, 2938 km2, LE90: 8.48 m, 5) SwedeSurvey photogrammetic data, 1433 km2, LE90: 2.60 m, 6) 1:25.000 contour data, 1152 km2, LE90: 3.8 m, 7) British lidar data (courtesy of Dr. Susan Conway, Open University), 532 km2, LE90: 0.96-4.63 m.

Availability from within WindPRO

The data are available directly from within windPRO in 10-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

Acknowledgement

  • The LMI are thanked for producing this digital elevation dataset – and disseminating it in the public domain and thus for aiding the development of renewable energy - and wind energy in particular.
