The utility model provides a regional spatial information detection device, the device include spatial information collector and map synthesizer, the spatial information collector is connected with the map synthesizer, the environmental data in acquisition area territory to transmission environmental data gives the map synthesizer, and regional spatial position information is oriented to the map synthesizer, and the parallel growth becomes the regional space image information that regional spatial position information corresponds, and this environmental data includes infrastructure's space characteristic, multimedia information, weather information and/or air quality. Realizing the regional environmental data of automatic acquisition, orienting regional spatial position information fast, in real time, the degree of accuracy of the spatial position information of orienting is very high, has improved regional reconnaissance efficiency greatly, the space image information in the region of formation, infrastructure's that can ground directly perceived display area spatial distribution to resource allotment can be fast, accurately carried out according to this space image information, resource allocation's efficiency has been improved greatly.
