Problems solved by technology

Since the number of spatial geometric objects included in a spatial dataset may be relatively large, and at the same time, the amount of spatial data contained in spatial geometric objects may also be relatively large. At present, this spatial data processing method consumes a large amount of computing resources and causes Spatial data processing efficiency is low

Abstract

The invention discloses a spatial data processing method and device, and relates to the technical field of data processing. One specific embodiment of the method comprises the steps of obtaining at least two types of spatial data sets; constructing a spatial index for the spatial data set; constructing a spatial geometry group according to the spatial index and the at least two types of spatial data sets; and putting the spatial geometry group into a message queue, and performing spatial correlation calculation on the spatial geometry group through an idle thread which is a thread for processing spatial data in the spatial data set. According to the embodiment, computing resources can be effectively balanced, consumption of the computing resources is reduced, and meanwhile the spatial data processing efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a method and device for spatial data processing. Background technique [0002] In recent years, with the abundance of space measurement methods, the improvement of measurement accuracy, and the continuous popularization of space-time sensors such as GPS and other equipment, space-time data has been used more and more. For example, we can monitor land state changes in different regions by combining and processing spatial data such as remote sensing data and land cover data. For another example, through the associated trajectory data of the taxi and the state information of the taxi itself, a series of efficient parking and pickup locations can be mined, and these locations can be recommended to empty drivers, ultimately increasing the utilization rate of the vehicle. It can be seen from this that finding out the correlation between different types of spatial ...
