A natural resource vector-oriented surface coverage change statistical processing method

Abstract

The invention discloses a natural resource vector-oriented surface coverage change statistical processing method and a storage medium. According to the method, administrative division is taken as a statistical unit, data of a plurality of different historical periods are matched, precisely spliced and cut, statistical analysis of different ground class classification codes is carried out after surface covering layer space superposition, and finally different types of statistical data reports are selected according to needs and are output. Statistical analysis is carried out by taking administrative division as a statistical unit; the volume of each data processing task is reduced; parallel processing resources of an existing computer can be utilized; A large amount of historical data oriented to natural resource vector surface coverage is processed at the same time, the processing speed and the processing efficiency are improved, query can be carried out in a mode of combination of administrative division codes and ground class distribution codes, and classification of different administrative divisions, ground class classification, classification area summarization and multi-dimensional extraction are achieved.

Description

Technical field [0001] The present invention relates to the field of land and resources statistics, and in particular, to a method for statistical processing of vector land cover changes oriented to natural resources. The historical land resources of a place can be statistically analyzed with the same administrative division as a unit, thereby facilitating the use of multi-core computing resources. Parallel processing calculations. Background technique [0002] Land surface cover refers to the complex of various material types on the earth's surface and their natural attributes and characteristics. Its status and changes are indispensable and important sciences in environmental change research, earth system model simulation, geographic national conditions monitoring, and sustainable development planning. Data and key parameters. Existing results are mostly stored and expressed in the form of remote sensing images. In recent years, with the advancement of high-resolution and sho...

Problems solved by technology

[0006] Under the background that the monitoring of natural resources and the environment is generally valued, change statistics have become an effective means of information acquisition, and the existing methods and software are still unable to provide professional guidance for the entire operation process and technical details

The latest research papers provide a change detection method based on remote sensing images, but the operability is poor and cannot be applied to large-scale vector data

Mainstream commercial and open source software only provide basic spatial analysis operation tools, but cannot effectively model complex processes

[0007] (2) Unable to effectively connect existing analysis methods with high-performance computing facilities to improve processing efficiency

If the existing methods or algorithms are completely reconstructed and developed, the work cost is too high, which is not conducive to the rapid development of statistical analysis of changes
