The overall objective of our research project is to understand the spatial inequality in health in Accra, the capital city of Ghana. We also utilize GIS technology to measure the association of adverse health and mortality outcomes with neighborhood ecology. We approached this in variety of ways, including multivariate analysis of imagery classification and census data. A key element in the research has been to obtain in-person interviews from 3,200 female respondents in the city, and then relate health data obtained from the women to the ecology of the neighborhoods in which they live. Detailed maps are a requirement for these field-based activities. However, commercially available street maps of Accra tend to be highly generalized and not very useful for the kind of health and social science research being undertaken by this project, The purpose of this paper is to describe street maps that were created for the project's office in downtown Accra and used to locate households of respondents. They incorporate satellite imagery with other geographic layers to provide the most important visual interpretation of the linkage between imagery and neighborhoods. Ultimately, through a detailed analysis of spatial disparities in health in Accra, Ghana, we aim to provide a model for the interpretation of urban health inequalities in cities of urbanizing and often poor countries.
我们研究项目的总体目标是了解加纳首都阿克拉市健康状况的空间不平等现象。我们还利用地理信息系统(GIS)技术来衡量不良健康状况和死亡率与社区生态之间的关联。我们通过多种方式来实现这一目标,包括对图像分类和人口普查数据进行多变量分析。该研究的一个关键要素是对该市3200名女性受访者进行面对面访谈,然后将从这些女性身上获取的健康数据与她们所居住社区的生态环境联系起来。详细地图是这些实地活动的必备条件。然而,阿克拉市市面上的街道地图往往高度简化,对于本项目所开展的这类健康与社会科学研究用处不大。本文旨在描述为该项目位于阿克拉市中心的办公室制作的、用于确定受访者家庭位置的街道地图。这些地图将卫星图像与其他地理图层相结合,以便对图像与社区之间的联系提供最重要的视觉解读。最终,通过对加纳阿克拉市健康状况空间差异的详细分析,我们旨在为城市化且往往较为贫穷的国家的城市中城市健康不平等现象的解读提供一个模型。
