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.
  • Question: Is other versions of the Taiwan elevation models available? Answer: Yes, the National Development Council of Taiwan has also released elevation models with version years 2016 and 2018. If you need those, please consult the website for the National Development Council of Taiwan - see the external links below.
