Terra Populus, or TerraPop, is a cyberinfrastructure project that integrates, preserves, and disseminates massive data collections describing characteristics of the human population and environment over the last six decades. TerraPop has made a number of GIScience advances in the handling of big spatial data to make information interoperable between formats and across scientific communities. In this paper, we describe challenges of these data, or 'deserts in the deluge' of data, that are common to spatial big data more broadly, and explore computational solutions specific to microdata, raster, and vector data models.
“Terra Populus”（简称“TerraPop”）是一个网络基础设施项目，它整合、保存并传播了大量描述过去六十年来人口与环境特征的数据集合。TerraPop在处理大规模空间数据方面取得了多项地理信息科学进展，以使信息在不同格式之间以及跨科学领域实现互操作。在本文中，我们描述了这些数据所面临的挑战，即更广泛意义上空间大数据中常见的“数据洪流中的沙漠”，并探索了针对微观数据、栅格数据和矢量数据模型的计算解决方案。
