大数据是一种概念,一种应用计算机软件进行数据信息处理、分析、捕捉的综合性信息资产的概念,也可以称之为是一种具有海量数据分析能力的数据管理系统。大数据最初仅仅是融合到信息产业的发展过程中,后期逐渐延伸至医疗、交通、教育等领域,且产生了广泛的影响。大数据中具有多种带有空间属性的数据集,这种数据集为城市规划的发展带来了全新的方向,而大数据与传统小数据在技术方法上存在着显著的差异,也为城市规划研究方法带来了一定的挑战。基于此,城市规划在大数据时代下,需要辩证的看待大数据的应用价值,借助其优势实现城市规划信息化与现代化的发展。 Big data is a concept. The concept of a comprehensive information asset that uses computer software to process, analyze and capture data information can also be called a data management system with massive data analysis capabilities. At first, big data was just integrated into the development of the information industry. Later it gradually extended to medical, transportation, education and other fields, and had a wide range of impacts. In big data, there are many kinds of datasets with spatial attributes. These datasets bring a brand new direction for the development of city planning. However, there are significant differences in technical methods between big data and traditional small data, Planning research methods have brought some challenges. Based on this, under the era of big data, urban planning needs dialectical application of the value of big data, with the help of its advantages to realize the urban planning informatization and modernization.
