However, the analysis of remote sensing data is carried out from the data appearance characteristics, and other location analysis methods need other information reference points to construct complex tool models for positioning, which is too cumbersome for the location analysis of data objects with geographic attribute descriptions, resulting in The efficiency is low, and for data sets of specific topics (for example, when two or more attributes of the data object contain geographic description information), the accuracy of the analytical results of geographic information is poor and not perfect enough

Abstract
The invention discloses a data processing method and device. The method comprises the steps of preprocessing data sources, and outputting data objects with not less than two geographic attributes; foreach output data object, in order to obtain a geographic coordinate, performing the following processing processes of extracting geographic description information of the data object in each geographic attribute, obtaining the geographic description information formed by splicing the geographic description information of the at least two geographic attributes, carrying out address resolution on the geographic description information of each geographic attribute and the geographic description information formed by splicing the geographic description information of the at least two geographic attributes, determining the corresponding geographic coordinate, verifying whether the geographic spatial distance between the geographic coordinates is legal or not, thereby determining selectable geographic coordinates, describing the relative accuracy of geographic locations according to the geographic description information corresponding to the selectable geographic coordinates, and selectingone of the selectable geographic coordinates as the geographic coordinate of the current data object; and configuring new attributes for the data object which obtains the geographic coordinate. According to the method and the device, the geographic information resolution accuracy can be improved.
Description
technical field [0001] The present application relates to the technical field of data processing, and in particular to a data processing method and device. Background technique [0002] For data objects containing geographic information, data analysis and data mining combined with geographic information context will help users understand data content and data relationships, as well as location-based applications and in-depth analysis. [0003] When the data object lacks geographic information for quantitative description, it is generally converted with the help of location reference, remote sensing data or other location analysis means. However, the analysis of remote sensing data is carried out from the data appearance characteristics, and other location analysis methods need other information reference points to construct complex tool models for positioning, which is too cumbersome for the location analysis of data objects with geographic attribute descriptions, resulting ...
