Abstract

Embodiments of the invention provide an emergency thematic map generation method and system. The method comprises the steps of extracting ground objects in disaster emergency information, and in combination with a pre-established place name search table, obtaining disaster emergency demand data corresponding to the ground objects; according to each type of a disaster emergency demand, obtaining abase map of a thematic map of the type of the disaster emergency demand; and for each type of the disaster emergency demand, according to all types of the disaster emergency information reflecting thetype of the disaster emergency demand, superposing the disaster emergency demand data corresponding to all the ground objects in each type of the disaster emergency information reflecting the type ofthe disaster emergency demand to the base map of the thematic map of the type of the disaster emergency demand according to geographic coordinate information of the ground objects, thereby generatingthe thematic map of the type of the disaster emergency demand. According to the emergency thematic map generation method and system provided by the embodiments of the invention, the thematic map of the emergency demand can be quickly generated, so that the emergency rescue time is effectively shortened.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of data processing, and in particular to a method and system for generating emergency thematic maps. Background technique [0002] Thematic maps are an important means of information expression and transmission. Thematic map, also known as special map, is to highlight and perfectly represent one or several elements related to the theme on the geographic base map according to the requirements of the map theme, so that the content of the map is thematic and expressed in different forms , purpose-specific maps. [0003] The content of a thematic map consists of two parts: one is the thematic content, that is, the natural or socio-economic phenomena and their related features highlighted on the map; There are mainly graticules, water systems, boundaries, and residential areas. [0004] With the accelerated pace of urban construction in my country and the continuous growth of the size...
