ABSTRACT

NDS is an interactive, web-based system, for the visualization of multidimensional neighborhood dynamics across the 50 largest US Metropolitan Statistical Areas (MSAs) from 1980 to 2010 (http://neighborhooddynamics.dreamhosters.com). Four different visualization tools are developed: (1) an interactive time slider to show neighborhood classification changes for different years; (2) multiple interactive bar charts for each variables of each neighborhood; (3) an animated neighborhood’s trajectory and sequence cluster on a self-organizing map (SOM) output space; and (4) a synchronized visualization tool showing maps for four time stamps at once. The development of this interactive online platform for visualizing dynamics overcomes many of the challenges associated with communicating changes for multiple variables, across multiple time stamps, and for a large geographic area when relying upon static maps. The system enables users to select and dive into details on particular neighborhoods and explore their changes over time.

摘要

NDS是一个基于Web的交互式系统，用于可视化显示1980年至2010年美国50个最大的都市统计区（MSA）中的多维邻域动态（http://neighborhooddynamics.dreamhosters.com）。开发了四种不同的可视化工具：（1）交互式时间滑块，以显示不同年份的邻里分类变化；（2）每个邻域的每个变量有多个交互式条形图；（3）在自组织地图（SOM）输出空间上的动画邻域的轨迹和序列簇；（4）同步可视化工具，一次显示四个时间戳的地图。这个交互式在线平台的开发使动态效果可视化，克服了与跨多个时间戳交流多个变量的更改相关的许多挑战，以及依赖静态地图时的大地理区域。该系统使用户可以选择并深入了解特定社区的详细信息，并探索其随着时间的变化。
