The invention discloses a global dynamic heterogeneous spatial information collaborative plotting and spatial knowledge
service system. On the basis of plotting data obtained by a collaborative plotting platform,
mass related heterogeneous spatial information of Africa is collected, and a plotting
knowledge base is generated through
data integration and knowledge reasoning; on the basis of the plotting
knowledge base, a knowledge model is built by means of
data mining, hot spot image-text association and the like,
knowledge services with the text that 'a Chinese is attacked in Africa', and the texts of 'China-Africa international cooperation', 'Africa travel' and the like being themes are carried out, visual representation is performed on hot spot area information by means of hot spot image-
text generation, network map diaries and the like, a
knowledge base (stored data) is built, finally, the African spatial knowledge
service system based on the collaborative plotting technology is achieved, and spatial information active services are provided for the public, the government and associated users.
