Grade A Tertiary Hospital Accessibility by Ga2SFCA in China

Grade A Tertiary Hospital Accessibility by Ga2SFCA in ChinaThe road network data utilized in this study is derived from OpenStreetMap (OSM), while population data is sourced from LandScan, both corresponding to the year 2023. Hospital data, encompassing 1,843 grade A tertiary hospitals, was obtained from YAOZH(https://db.yaozh.com/) in May 2024. Accessibility modeling is conducted using the Gaussian two-step moving search method, with a maximum search radius of 60 minutes, ensuring a rigorous spatial analysis of healthcare accessibility.

基于Ga2SFCA的中国甲等三级医院（Grade A Tertiary Hospital）可达性分析
本研究所用道路网络数据取自开放街道地图（OpenStreetMap），人口数据取自LandScan，两类数据均为2023年版本。涵盖1843家甲等三级医院的医院数据集，于2024年5月从药智网（YAOZH，https://db.yaozh.com/）获取。本次可达性建模采用高斯两步移动搜索法（Gaussian two-step moving search method，缩写为Ga2SFCA），设置最大搜索半径为60分钟，以保障医疗可达性空间分析的严谨性。
