Abstract
Advances in information technology have promoted the development of smart cities. Under the umbrella of building smart cities, the computer digital surveying and mapping geographic information industry builds an important spatial information infrastructure for smart cities by building a smart city spatio-temporal information cloud platform, and provides intelligent spatio-temporal carriers for smart cities. Based on this research background, the paper analyzes the positioning of computer digital geographic information in the construction of smart cities, and proposes the concept of geographic platform and its value in smart cities: spatial information resource sharing, ubiquitous information support and collaborative management.
