In 1998, the National Research Council published People and Pixels: Linking Remote Sensing and Social Science. The volume focused on emerging research linking changes in human populations and land use/land cover to shed light on issues of sustainability, human livelihoods, and conservation, and led to practical innovations in agricultural planning, hazard impact analysis, and drought monitoring. Since then, new research opportunities have emerged thanks to the growing variety of remotely sensed data sources, an increasing array of georeferenced social science data, including data from mobile devices, and access to powerful computation cyberinfrastructure. In this article, we outline the key extensions of the People and Pixels foundation since 1998 and highlight several breakthroughs in research on human–environment interactions. We also identify pressing research problems—disaster, famine, drought, war, poverty, climate change—and explore how interdisciplinary approaches integrating people and pixels are being used to address them.

20 年后的人和像素：当前的数据格局和融合人口和环境数据的研究趋势

1998 年，国家研究委员会出版了《人物与像素：将遥感与社会科学联系起来》。该卷侧重于将人口和土地利用/土地覆盖的变化联系起来的新兴研究，以阐明可持续性、人类生计和保护问题，并导致农业规划、灾害影响分析和干旱监测方面的实际创新。从那时起，新的研究机会出现了，这要归功于越来越多的遥感数据源、越来越多的地理参考社会科学数据（包括来自移动设备的数据）以及对强大计算网络基础设施的访问。在本文中，我们概述了 People and Pixels 基金会自 1998 年以来的主要扩展，并重点介绍了人与环境相互作用研究方面的几项突破。
