The study of colleges students returning to campus under the epidemic situation based on GIS

The Novel Coronavirus Diseases 2019 (COVID-2019) is an international public health emergency that has drawn wide attention in the world. Affected by the COVID-2019, almost all colleges and universities across the country have decided to postpone the start date. College students are characterized by a wide range of personnel sources, and many uncertain and complex factors on the way back. Therefore, Major universities should take measures to prevent and control the epidemic, and arrange for students to return to Campus under the premise of traveling in batches according to regional location and personnel characteristics. Geographic Information System (GIS) is a computer system used for collecting, storing, processing, analyzing, and displaying geospatial data, which provides important technical support for real-time epidemic transmission monitoring, emergency resource management, comprehensive social governance, public cognition, and other aspects. The purpose of this paper is to study the application of GIS in the formulation of measures for returning to Campus in colleges and universities under the epidemic situation, and to give a preliminary strategy for batching and staggered start of school.
