Description

technical field [0001] The invention relates to the technical field of urban comprehensive emergency management, in particular to a plotting method of a rapid situational plotting system based on a GIS platform and a touch screen device. Background technique [0002] In recent years, all kinds of public emergencies have occurred frequently in our country. Every year, the casualties caused by public emergencies are more than one million, and the comprehensive economic loss is as high as hundreds of billions of yuan, which has caused adverse effects and serious harm to the public safety environment. Public emergencies bring heavy losses to people's lives and property, and restrict the comprehensive, coordinated and sustainable development of the national economy. Undoubtedly, a strong emergency response capability for public emergencies is the key to reducing losses and creating a good social environment. [0003] The comprehensive emergency platform based on the geographic i...
