The Rural Access Index is a measure of access developed by the World Bank and has been incorporated into the Sustainable Development Goals (SDGs) as indicator 9.1.1. This measures the proportion of the rural population living within 2 km of an all‐season road, using GIS layers and relying on three data sources: population, road network location and condition. Open GIS data are used for population and road location, but there are challenges to define the all‐season status of roads. Every country measures road condition differently and against different parameters, which makes consistency of the all‐season status between countries difficult. This article reports on research to refine the GIS methodology for assessing SDG 9.1.1 to make it more sustainable, repeatable and consistent by using geospatial data and tools, based on trials in four countries—Ghana, Malawi, Myanmar and Nepal—which were selected for their diversity of environment and data.

衡量SDG 9.1.1的农村准入

农村获取指数是世界银行制定的获取获取指标，并已作为指标9.1.1纳入可持续发展目标（SDG）。该方法使用GIS图层并依靠三个数据源（人口，路网位置和状况）来衡量全季节道路2公里以内的农村人口比例。开放的GIS数据用于人口和道路位置，但是定义道路的全季节状态仍存在挑战。每个国家/地区对道路状况的测量方式不同，针对的参数也不尽相同，这使得国家/地区之间全季节状态的一致性变得困难。本文报告了有关完善GIS方法以评估SDG 9.1.1的研究，该方法通过使用地理空间数据和工具使其更具可持续性，可重复性和一致性，
