## Description

The DTM is a digital terrain model of the Hong Kong Special Administrative Region\. It shows the topography of terrain \(including non\-ground information such as elevated roads and bridges\) in 5\-metre raster grid with an accuracy of ±5m\. If land area is covered by vegetation, the terrain will be depicted by the height of vegetation\.
