2006年1月，美国地质调查局地理空间信息办公室成立了地理空间信息科学卓越中心（CEGIS）。CEGIS的愿景是进行，领导和影响美国国家空间数据基础设施（NSDI）所需的研究和创新解决方案，以及新兴的贸易，产品或公司名称的任何使用仅用于描述目的，并不意味着美国政府地理空间网络的认可。该使命是提供领导，以确定，进行，并在国家重要性的GIScience研究问题合作;评估，影响，并建议实施地理空间数据和应用的技术创新;并保持世界一流的专业知识，领导能力和知识体系，以支持国家空间数据基础设施。为了完成这一使命，CEGIS的大部分研究都是制图性质的。目前（2007年）的制图项目包括数据集成，综合，多分辨率光栅投影在近实时使用并行和网格计算在万维网上，分形和变异函数分析的规模和分辨率对地理空间过程的影响，并制定了国家地图本体的研究调查。国际制图协会（伊卡）各委员会对其中许多项目感兴趣。本文和演示文稿将提供这些调查的目标和结果。将介绍从这些研究调查中产生的制图产品的例子，以及这些产品作为美国地质勘探局开发国家地图和国家空间数据基础设施的系统开发原型的意义。
In January 2006, the U.S. Geological Survey’s Geospatial Information Office established the Center of Excellence for Geospatial Information Science (CEGIS). The vision for CEGIS is to conduct, lead, and influence the research and innovative solutions required by the National Spatial Data Infrastructure (NSDI) of the USA and the emerging Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government GeoSpatial Web. The mission is to provide leadership to identify, conduct, and collaborate on GIScience research issues of national importance; to assess, influence, and recommend for implementation technological innovations for geospatial data and applications; and to maintain world-class expertise, leadership, and a body of knowledge in support of the NSDI. To accomplish this mission much of the research of CEGIS is cartographic in nature. Current (2007) cartographic projects include research investigations of data integration, generalization, multi-resolution raster projection in near real-time using parallel and grid computing on the World Wide Web, fractal and variogram analysis of scale and resolution effects on geospatial processes, and developing an ontology for The National Map. Many of these projects are of interest to the Commissions of the International Cartographic Association (ICA). This paper and presentation will provide the objectives and results of several of these investigations. Examples of cartographic products generated from these research investigations will be presented and the significance of those products to serve as prototypes for system developments for the USGS effort to develop The National Map and the NSDI.
