Abstract Remote sensing has become an important technical means and method in the survey of geological disasters. This paper summarized the interpretation mark features of landslide and debris flow, built the data model of geological disaster marks and database, coded the geological disaster marks, and finally developed the management system of interpretation marks on geological disaster based on Virtual Globe. This system is valuable in effective storage and management of geological disaster interpretation marks and in improvement of the efficiency of remote sensing interpreting task.
