Introduction

Taiwan Elevation Model 2020 - 20m resolution:
The National Development Council of Taiwan has released a digital elevation model (DTM) that covers the region of Taiwan. Most parts of the main island of Taiwan are covered, along with some outlying islands (Guishan Island, Green Islands, Orchid Islands & Xiao Liu Qiu (Liuqiu))

Dataset Overview

  • Spatial Coverage: Taiwan and minor outlying islands.
  • Resolution: 20m
  • Data type: Digital Terrain Model (DTM)
  • Coordinate System: TWD97 (EPSG:3826) - in original data.
  • Version: 2020 (with data accessed in spring 2022)
  • Vertical accuracy: N/A

Usage Notes

  • Question: In the original data - a small part of the model is missing between Hsinchu and Miaoli?
  • Answer: According to the National Develiopment Council, this is due to air traffic control factors in the area, and thus no information is available. In the model delivered with windPRO, this particular part has been patched with data from the Copernicus GLO-30 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 The National Development Council of Taiwan 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.
