Abstract
In the current information age, digital technology has become an essential part of urban civilisation. The digital city has been transformed from a novel concept to a practical and effective means of supporting urban planning and management. However, there are various definitions of a digital city and each has a unique significance. By comparing these digital city concepts, we examined common aspects of digital city definitions and propose an urban digital operating system (Urban DOS) that will be useful to improve life quality, socioeconomic functions and sustainable development in a city and its surrounding areas. The technical basis for the Urban DOS is the intersection between technology-oriented products (TOPs) and customised application products (CAPs). We then develop a procedure for designing a framework for a digital city based on Urban DOS with TOPs and CAPs. To explain such digital city concepts and applications, we demonstrate the initial development of Urban DOS for Lijiang City.
