3D Visualization Map (2017) is a form of digital surface model used for spatial data visualization, query and analysis. The 3D Visualization Map (2017) is tiled with dimension of 150m x 150m. 3D Visualization Map (2017) in different districts will be launched by phases and will gradually cover the whole Hong Kong in the future.

Users could visit the Hong Kong GeoData Store to preview and download the 3D Visualization Map (2017) in open formats, i.e. tiled-OSGB or OBJ format.

Pedestrian Network is a set of 3D line features derived from road features and road furniture from Lands Department and Transport Department. A number of attributes are associated with the pedestrian network such as spatially related street names. Besides, the pedestrian network includes information like wheelchair accessibility and obstacles to facilitate the digital inclusion for the needy.

Users could visit the Hong Kong GeoData Store to preview and download the 3D Pedestrian Network.

The i-Series Digital Maps, including iB1000, iB5000, iB10000 and iB20000 Digital Topographic Map, iC1000 Digital Land Boundary Map, iG1000 Geo-reference Database and iGeoCommunity Database, provide more comprehensive datasets in new data formats.

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 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.

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.

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.

The aerial photo flight index shows the aerial photo and flight information, including photo number, shooting position, photo coverage, date of flight, flying height etc., of the aerial photographs taken by Survey and Mapping Office (SMO). There are three file formats, XLS / XLSX, KML and KMZ for download. The file in KML and KMZ file format is geo-referenced to World Geodetic System (WGS84), containing both aerial photo and flight information, while the file in XLS / XLSX file format only contains the aerial photo information.
