Embodiment Construction

[0065] Preferred embodiments of the present disclosure will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0066] The data structure of the relevant geographic object model is a two-tuple expressing the relationship between spatial objects and spatial objects. The relationship between the spatial objects is usually a topological relationship, as shown in formula (1).

[0067] S = (G, R) (1)

[0068] In formula (1), S is the real space world, G is the geographic space object, and R is the topological relationship between the space objects.

[0069] The topological relationship between spatial objects needs to be obtained through the Euclidean spatial principle by using the location information of spatial objects. For example, the topological relationship between spatial o...

Abstract

The invention discloses a spatial data processing method and device. The method comprises the following steps of: receiving a command for drawing a spatial object; according to the command, obtaining the cartographic data of the spatial object from a spatial data cartographic model which is constructed in advance, wherein the cartographic data comprise the spatial information, the attribute information and the semantic information of the spatial object, wherein the spatial information and the semantic information are stored in an associative manner; according to the obtained cartographic data, drawing the spatial object. According to the method, the spatial object is drawn according to the spatial data cartographic model which is constructed in advance, the spatial information and the semantic information of the spatial object are integrally stored to improve the drawing speed, and the expression of the spatial object is more accurate by adding the semantic information.

Description

technical field [0001] The present disclosure relates to the field of communication and computer technologies, and in particular to a spatial data processing method, device and terminal equipment. Background technique [0002] With the rapid development of network technology, large-scale data exchange has become the main means of data sharing. Especially in recent years, with the continuous upgrading of spatial data collection methods and the substantial improvement of data collection efficiency, various industries have established large-scale spatial database systems. On the one hand, these data are distributed and used in electronic form, and on the other hand, they are applied in the form of paper-based thematic maps. Therefore, based on the spatial database system, how to express professional cartography efficiently and quickly to form standardized map products has become a research hotspot in the field of digital cartography. [0003] Relevant spatial data mapping sof...
