Digital Terrain Model (DTM)

Update Frequency: As and when necessary

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.
