The new 432-page “Hong Kong Guide” provides detailed maps of Hong Kong with indexes for streets, places and villages, estates and buildings, schools, public services, and leisure and cultural facilities, as well as information on public transportation. The “streets” and “places and villages” indexes can serve as gazetteers for names of streets and geographical places in Hong Kong. With the theme “Milestones in Survey and Mapping”, the “Hong Kong Guide” 2020 reviews the development of survey and mapping technologies and map products in Hong Kong over the past half-century, and showcases the upcoming survey and mapping services.
