本文阐述了数据可视化的发展、定义以及作用等基本知识.利用R语言与BDP(Business Data Platform)商业数据平台对中国地震台网近一年3.0级以上地震进行可视化处理.首先进行数据爬取,对数据进行清洗;其次进行R语言的数据可视化;最后利用BDP平台提供的地理信息系统功能,将地震数据与地理空间信息相结合,生成了地震热力图、地震点分布图等可视化效果.实验结果表明,基于R语言与BDP的地震数据可视化方法具有较好的效果和可行性.可视化分析揭示了地震活动的空间分布特征和时序变化规律,为地震预测和防灾工作提供了重要参考.
Visualization of Earthquake Data Based on R Language and BDP
This article elaborates on the development,definition,and role of data visualization.This study utilizes R language and BDP(Business Data Platform)to visualize earthquakes of magnitude 3.0 and above in the China Seismic Network over the past year.Firstly,perform data crawling and clean the data.Next,R language is used for data visualization.Finally,leveraging the geographic information system functionality provided by the BDP platform,earthquake data is combined with spatial information to generate visualizations such as earthquake heatmaps and point distribution maps.Experimental results demonstrate that the earthquake data visualization method based on R language and BDP is effective and feasible.The visual analysis reveals the spatial distribution characteristics and temporal variations of earthquake activity,providing important references for earthquake prediction and disaster prevention.
