With the development of information science and technology, how to achieve the digitalization and visualization of geological disaster emergency scheme is an important research subject in the geological disaster emergency command system. This paper designs a visualization model of geological disaster emergency scheme, which was divided into three main steps, including emergency scheme structuring, visualization modeling based on ontology and visualization technology. Based on this, computer technology, GIS(Geographic Information System) technology and network information technology are used to develop the visualization software result of geological disaster emergency scheme. This paper aims to provide a set of scheme for the visualization work of emergency scheme. It contributes to improve the operability of the emergency scheme and provide an intuitionistic intelligent auxiliary means with geological disaster emergency response.
