Geographic information data processing method and device

Abstract

The embodiment of the invention provides a geographic information data processing method and device. The geographic information data processing method comprises the following steps: acquiring geographic latitude and longitude coordinates of a spatial entity object to be inquired, and converting the geographic latitude and longitude coordinates into corresponding grid codes; inquiring grid elements in a database by use of the converted grid codes, and determining at least one object identifier corresponding to the grid codes, wherein corresponding relationships between the grid codes and the corresponding object identifiers are stored in the grid elements; inquiring an object table according to the determined object identifiers to obtain attribute information of objects identified by the corresponding object identifiers, wherein the object identifiers and the attribute information of the corresponding objects are stored in the object table; and determining attribute information of the spatial entity object to be inquired from the obtained attribute information of the objects. According to the embodiment of the invention, spatial inquiry conditions are converted into numerical matching of the grid codes, so that the effect of efficiently and accurately acquiring result data of geographic information data operation is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of geographic information, and in particular, to a geographic information data processing method and device. Background technique [0002] GIS (Geographic Information System, geographic information system) technology is a technology that combines geography, cartography, remote sensing and computer science, and is widely used in different fields, such as navigation, space research and so on. [0003] In GIS, the geographic latitude and longitude coordinate layer is generally used as the basis of geographic information data organization, and based on this, corresponding operations such as query and statistics are performed based on the latitude and longitude coordinates of physical space objects. However, the longitude and latitude coordinates cannot uniquely identify the location of the entity space object, and the assignment of the identification ID of the space entity object is random....
