Our relationship in local or global network, whether its physical relation or virtual relation, are changing with the attack of COVID 19. Travel across the international border are reduced by 90% and group meetings are minimized by sizes and chances. Global contacts are all shifted to virtual world, while people work at home or locally during quarantine. This will change local activity and territory. This tendency questions how the city’s usage pattern and form will change in the near future. To foresee urban changes in post pandemic era, we try to redefine and delineate local territory as a first step.
