摘要
城市体检作为发现城市病、助力城市更新的重要抓手和重点工作,已在全国各地积极开展。其涉及面广、数据多源异构,包含基础地理数据、网络大数据、统计数据等,引发时空数据挖掘的研究和应用。而GIS技术作为一种强大的空间分析工具,在数据的可视化、空间分布分析方面有较大的优势,能为城市体检提供新的应用途径。通过梳理城市体检的概念和GIS技术在城市体检中应用的优势,探究GIS技术在城市体检工作中的具体运用,以及存在的困难。表明GIS技术对于城市体检指标数据的获取、城市问题的可视化以及提高城市体检评估结果的精确性方面有十分重要的意义。
As an important tool and key task for discovering urban diseases and assisting urban renewal,urban physical examinations have been actively carried out throughout the country.It involves a wide range of data sources and heterogeneity,including basic geographic data,network big data,statistical data,etc.,triggering research and application of spatiotemporal data mining.As a powerful spatial analysis tool,GIS technology has significant advantages in data visualization and spatial distribution analysis,and can provide new application avenues for urban health examinations.By sorting out the concept of urban physical examination and the advantages of GIS technology in urban physical examination,this study explores the specific application of GIS technology in urban physical examination work,as well as the existing difficulties.This indicates that GIS technology is of great significance in obtaining urban physical examination indicator data,visualizing urban problems,and improving the accuracy of urban physical examination evaluation results.
