Microsoft TerraServer：一个空间数据仓库
Microsoft TerraServer: A Spatial Data Warehouse
摘要：
TerraServer将地球的航空、卫星和地形图像存储在可通过Internet访问的SQL数据库中。它是世界上最大的在线地图集，结合了来自美国地质调查局（USGS）和SPIN-2的5 TB图像数据。本报告介绍了基于我们过去一年的经验进行的系统重新设计。它还报告了过去一年的使用和运营结果-超过20亿次网络点击和超过20 TB的互联网图像。互联网浏览器为数据提供直观的空间和文本界面。用户不需要特殊的硬件、软件或知识来定位和浏览图像。本文描述了如何将数TB的“互联网不友好”的地理空间图像清理和编辑成数亿个“互联网友好”的图像瓦片，并加载到SQL数据仓库中。Microsoft TerraServer的开发实践表明，通用关系数据库技术可以管理大规模的影像数据库，Web浏览器可以成为一个很好的地理空间影像展示系统。
英文摘要：
The TerraServer stores aerial, satellite, and topographic images of the earth in a SQL database available via the Internet. It is the world's largest online atlas, combining five terabytes of image data from the United States Geological Survey (USGS) and SPIN-2. This report describes the system-redesign based on our experience over the last year. It also reports usage and operations results over the last year -- over 2 billion web hits and over 20 Terabytes of imagry served over the Internet. Internet browsers provide intuitive spatial and text interfaces to the data. Users need no special hardware, software, or knowledge to locate and browse imagery. This paper describes how terabytes of "Internet unfriendly" geo-spatial images were scrubbed and edited into hundreds of millions of "Internet friendly" image tiles and loaded into a SQL data warehouse. Microsoft TerraServer demonstrates that general-purpose relational database technology can manage large scale image repositories, and shows that web browsers can be a good geospatial image presentation system.
