Problems solved by technology

As the GIS platform with the highest application performance in the world, ArcGIS integrates a variety of rich algorithms in geographic computing, geostatistical analysis, and spatial analysis. The full computing power of high-performance multi-core computers, while the traditional serial algorithm can no longer meet the increasing processing needs of massive geographic data, resulting in low efficiency, especially for surveying and mapping production units, which directly affects the work progress
At present, there are some studies on improving the speed of geographic processing operations based on the ArcGIS platform, but they basically stay in the improvement o

Abstract

The invention provides a massive building pattern spot feature rapid calculation method and system, and the method comprises the steps: decomposing a total calculation task into a plurality of tasks according to the number of cluster nodes and the data size of building data and other data, and enabling each processor in a cluster to be able to distribute the tasks; adding the tasks into a queue ina descending order according to the scale, and sequentially distributing the tasks to idle computing nodes in the cluster until all the tasks are distributed; after each computing node receives the task, adding the to-be-calculated features into a subtask queue, sequentially distributing the to-be-calculated features to idle processors on the nodes for parallel processing until the subtasks are distributed, executing the distributed subtasks, calculating corresponding building features, and outputting building pattern spot feature calculation results to corresponding text files according to the sequence of the distributed building data IDs of the nodes; and merging the calculation results of the sub-tasks to obtain final architectural pattern spot feature data.

Description

technical field [0001] The disclosure belongs to the field of rapid calculation of massive geographic information data, and relates to a method and system for rapid calculation of features of massive architectural patterns. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the continuous development of information science, GIS data has gradually shown the characteristics of massive quantity and real-time. The processing, analysis, and mining of vector data are becoming more and more urgent, and the requirements for computing performance and efficiency of computers are getting higher and higher for geographic computing and statistical analysis. As the GIS platform with the highest application performance in the world, ArcGIS integrates a variety of rich algorithms in geographic computing, geostatistical analysis, and spatial analysis. ...
