Digital Maps
The SMO provides Topographic Maps, Orthophotos, Aerial Photographs, Land Boundary Maps, Geo-reference Database, GeoCommunity Database and 3D Spatial Data in digital form. Many utility companies, engineering consultants, IT consultants and education institutes including government departments have established their own automated mapping, facilities management, customer support and geographic information systems using the digital maps provided by the SMO as common reference.
The i-Series Digital Maps, including iB1000, iB5000, iB10000 and iB20000 Digital Topographic Map, iC1000 Digital Land Boundary Map and iG1000 Geo-reference Database, provide more comprehensive datasets in new data formats and enable users to select the seamless version covering users’ defined area-of-interest so that they do not need to combine discrete tiles of digital maps into one single file for their work.
The 1963 Orthophoto, which is a high resolution orthophoto compiled from aerial photographs taken in early 1963 covering most Demarcation Districts (DD) in the New Territories, was launched in 2013. The 1963 Orthophoto can be used for various applications requiring identification of old ground features.
The 3D Spatial Data, which was launched in 2012, is a set of digital data of 3D models featuring geometry model, texture map and textual attribute to represent the geometrical shape, appearance and position of three types of ground objects i.e. Building, Infrastructure and Terrain. The 3D Spatial Data can be used in the applications such as analysis, visualization and presentation in carrying out technical study or public consultation for different land development and infrastructure construction projects.
