Digital Orthophoto

Digital Orthophoto is an image map produced by the SMO featuring pictorial information of ground features as contained in geometrically rectified aerial photographs, coordinate reference in the Hong Kong 1980 Grid system and a uniform scale of representation.
Currently, the Digital Orthophoto has four series of products, namely DOP5000, DOP1000-1963, DOP1000-1982 and DOPM50-L0, which are classified based on the sizes of image resolution and the types of source photographs used. They are stored in the image formats of GeoTIFF and JPEG with associated geo-referencing data in a World format.

Geo-referenced Public Facility Data

Geo-referenced Public Facility Data contain 79 types of geo-referenced public facility data, which are available on the Hong Kong GeoData Store and DATA.GOV.HK for free download by the general public.
Users could visit the Hong Kong GeoData Store to preview the distribution of the selected type of public facility and download the geo-referenced data, with attributes including names, addresses, WGS84 Latitudes and Longitudes, and HK 1980 Grid coordinates in machine-readable formats of CSV, GeoJSON, GML, KML, as well as GeoData API.
SatRef GNSS Real Time Raw Data Streams
The Hong Kong Satellite Positioning Reference Station Network (SatRef) has been supporting high accuracy positioning applications for public since 2010. The reference stations receive real-time GNSS signals from GPS, GLONASS and Beidou satellites round-the-clock. The GNSS Real-time raw data streams are then instantaneously disseminated via DATA.GOV.HK as part of the Public Sector Information (PSI). They can be acquired by means of NTRIP with the appropriate settings.

Digital Terrain Model (DTM)
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.
