Problems solved by technology

Moreover, the current research on vector space data is relatively weak. Existing methods generally only encode, store and process spatially adjacent data according to the spatial proximity of vector space objects, without considering the data space complexity.

Abstract

The invention discloses an adaptive fault-tolerant processing method and system for spatial information data, which sequentially arranges the geometric center points in the vector space data according to the frequency of the geometric center points of the same line entity and surface entity appearing in the first N vector space data , the coded sequence of the point entity is calculated by constructing a binary tree with frequency, and the coded sequence corresponding to the line entity and surface entity is obtained through the frequency calculation, and the data processing or storage of the spatial information data is directly performed through the coded sequence; the point entity, the line entity in the spatial information data are Entities and surface entities are processed as mapping data in the form of code sequences, which can greatly compress the amount of data and improve data stability, so that the data deviation of continuous vector data in real-time reading can be reduced. Due to the use of data encoding formats, the The smaller data volume is convenient for data storage, which improves the retrieval and reading speed of spatial information data post-processing, and improves the fault tolerance of spatial data.

Description

technical field [0001] The disclosure relates to the fields of spatial data processing and geographic information data processing, and in particular to a method and system for adaptive fault-tolerant processing of spatial information data. Background technique [0002] Spatial information data is information that reflects the characteristics of geographical spatial distribution. Through the acquisition, perception, processing, analysis and synthesis of spatial information, it reveals the laws of regional spatial distribution and changes. Spatial information is transmitted by means of spatial information carriers (images and maps). Graphics are the main form of representing spatial information. The spatial information carrier represented by spatial information can be described as basic graphic elements such as points, lines, and planes. Only when spatial information is combined with attribute information and time information can the spatial information carrier be fully desc...
