Abstract

The invention discloses an ArcGIS-based vector data parallel processing method and system. The method comprises: acquiring a spatial range of a vector layer to be processed, dividing the spatial rangeinto multiple sub-spatial ranges, constructing multiple subtask information, starting multiple processes, setting ambient variable parameters of an ArcGIS vector data processing tool, calling the ArcGIS vector data processing tool, executing multiple subtasks, copying a resultant layer to a resultant database for the firstly completed subtask, and adding resultant data of the other subtasks sequentially to the resultant layer. The ArcGIS-based vector data parallel processing method and system have the advantages that vector big data processing tasks can be divided spatially into multiple calculation subtasks, the subtasks are parallelly processed with the ambient variable parameters of the ArcGIS vector data processing tool by using a multi-process technique and calling multiple ArcGIS vector data processing tools, parallel acceleration can be achieved for ArcGIS vector data processing, and vector big data can be processed more efficiently with ArcGIS.

Description

technical field [0001] The invention relates to high-performance geospatial computing technology, in particular to an ArcGIS-based vector data parallel processing method and system. Background technique [0002] The fast real-time processing of vector big data is one of the key problems to be solved in high-performance spatial computing. In the multi-core cluster parallel computing environment, the use of multi-thread or multi-process technology can make full use of parallel computing resources and realize the parallel computing of intensive tasks. accelerate. Due to the complex storage and calculation of vector data, the existing ArcGIS vector data processing tools cannot use parallel computing resources to process large vector data in parallel, resulting in low processing efficiency and low utilization of computing resources. Contents of the invention [0003] The technical problem to be solved by the present invention is that the above-mentioned existing ArcGIS vector ...
