To solve the problem of low efficiency and poor accuracy on spatial data retrieval

this paper proposes a scene similarity retrieval method based on spatial object shape description model

spatial relationship description model and adaptive scene similarity computing model.Spatial object shape description model can accurately retrieve database objects satisfied with the sample object shape constraints

and improve the space object shape recognition accuracy.Spatial relationship description model can retrieve database scenes satisfied with relationship constraints of the sample scene

and improve the spatial relationship description precision.Adaptive scene similarity computing model can mark and sequence complete or incomplete matching scenes satisfied with shape and relationship constraints

improve the rationality of similarity scores on retrieval results.Experiments of simulative and real scenes show the scene similarity retrieval has a good retrieval performance.
