Abstract: At present, the emergency response mode has been changed from "prediction-response" to "scenario-response". Emergency thematic map as an important content of emergency surveying and mapping, its production way should be changed according to the new mode. This paper introduces the definition of unconventional emergency scenarios and geographic scenarios, points out that geographic scenarios as the physical space in which various scenario elements exist or occur are the object of emergency mapping, discusses the principle and 4 main characteristics of rapid mapping of emergency scenario, proposes a cartographic information transmission model combining the traditional cartographic information transmission theory with the new emergency response mode, gives detailed explanations to the process of spatial information transmission and analyzes the spatial cognition of map senders and receivers which affects the efficiency of cartographic information transmission.

Key words: unconventional emergencies, emergency scenario, rapid mapping, information transmission model, spatial cognition
