Collaborative Research: A Digital Library Collection for Visually Exploring United States Demographic and Social Change

这个纽约市立大学和加州大学洛杉矶分校之间的合作项目是一个基于网络的材料，将使描述和探索的增长和社会变革在美国，因为它的开始收集。 从小学到研究生院的学生、图书馆用户、媒体以及所有其他对各种人口统计数据和其他数据相互关联感兴趣的人都可以访问它。 目前正在实施该项目，因此用户不需要高度的技术复杂性，即可将结果以地图和图表的形式可视化，下载数据以供进一步分析，并将数据与社会科学的具体问题联系起来，具体而言，以下内容将是该项目的一部分：1）1790年至2000年县级人口普查数据和地图，其中描绘了广泛的变化。2)区域级的人口普查数据和地图，从1910年的最大城市开始，一直扩展到1990年，1990年可用于整个国家。3）来自人口普查的街道和道路图层的数据，这是美国国家地图的一部分，用于定义人口普查区和其他人口普查地理。可用的图像和文本，可以在地理位置和相关的基础人口。获奖摄影记者Camilo Vergara在过去30年中记录了大城市的地区，他记录的图像说明了人口资料。 人口统计反过来又为他的照片提供了上下文信息。5）用于视觉显示和操作地图、数据、图像和文本的系统。这项工作借鉴了其他几个项目，包括国家历史地理信息系统（NHGIS），1790-2000年美国城乡社会变化的可视化和探索-交互式多媒体和基于网络的工具（都是由NSF资助的），和伟大的美国历史机器，以及纽约，洛杉矶，费城，印第安纳波利斯，芝加哥和其他地方的数字化努力。总之，数字图书馆是美国人口统计学、地理学和社会学的网格。该网格还可以容纳关于土地使用、交通、医疗保健等的其他材料的添加。提供的例子，特别是纽约和洛杉矶的主要大都市地区。所有材料都以标准格式编制，并与动态绘图系统和交互式多媒体查看器相结合，以提供方便用户的界面。 这些材料在加州大学洛杉矶分校和纽约市立大学的公共服务器上免费提供，供互动使用、下载、分享和增强。 此外，它们也可供其他数字储存库使用。明尼苏达州人口中心的NHGIS正在分发这些材料，这些材料最终将与NHGIS材料一起沿着存档在大学间政治和社会研究联合会。

This collaborative project between CUNY and UCLA is a collection of web-based materials that will enable depiction and exploration of growth and social change in the United States since its beginnings. It is accessible to students from elementary through postgraduate school, library users, the media, and all others interested in relating a variety of demographic and other data to one another. It is being implemented so a high level of technical sophistication is not required of users to visualize the results in the form of maps and charts, to download the data for further analysis, and to relate the data to specific issues in the social sciences.Specifically the following elements will be part of the project:1) Census data and maps at the county level from 1790 through 2000, which depict the sweeping change. 2) Census data and maps at the tract level, beginning with the largest cities in 1910 and expanding until 1990, when they become available for the entire country.3) Data from the street and road layer of the Census, which are part of the national map of the United States and used to define Census tracts and other Census geography.4) Available images and text that can be geographically located and related to the underlying demography. The images recorded by the award winning photojournalist Camilo Vergara, who has documented areas of the large cities for the past 30 years, illustrate the demographic material. The demographics, in turn, provide contextual information for his photos.5) A system for visually displaying and manipulating the maps, data, images, and texts. This effort draws on several other projects, including, the National Historic Geographic Information System (NHGIS), Visualizing and Exploring United States Urban and Rural Social Change, 1790-2000 --Interactive Multimedia and Web Based Tools (both funded by NSF), and the Great American History Machine, as well digitization efforts in New York, Los Angeles, Philadelphia, Indianapolis, Chicago and elsewhere.In short, the digital library serves as a demographic, geographic and social grid for the United States. The grid also can accommodate the addition of other materials on land use, transportation, health care, and the like. Examples are provided, especially for the major metropolitan areas of New York and Los Angeles. All materials are developed in standard formats and integrated with a dynamic mapping system and an interactive multimedia viewer to provide a user-friendly interface. Materials are freely available for interactive use, downloading, sharing and enhancement on publicly accessible servers at UCLA and CUNY. Also, they are being made available to other digital repositories. The NHGIS at the Minnesota Population Center is distributing the materials, which ultimately will be archived along with the NHGIS materials at the Inter-University Consortium for Political and Social Research.
