Libraries Faculty and Staff Scholarship and Research
Purpose – This study aims to establish common metrics for web-based mapping applications to facilitate user decision making and enhance information providers’ product design.
Design/methodology/approach – The metrics were developed from a combination of literature review and case studies. From the literature review, we identified three major areas of assessment for web-based mapping applications. We then studied six online applications to refine the metrics.
Findings – Our results suggest that web-based mapping applications can be evaluated from three major aspects: data content, GIS functionality, and usability. We have developed detailed measures for each factor through our evaluation of the six …

We use the high resolution North American Regional Analysis (NARR) dataset to build for the United States a Temperature Change Index (TCI) based on four contributing variables derived from the layer-averaged temperature and lapse rate of the 1000mb - 700mb layer (near-surface to 3000 meters) for the 1979-2008 period. The analysis uses Geographic Information Systems (GIS) methods to identify distinct regional patterns based on aggregate temperature trends and variability scores. The resulting index allows us to identify and compare regions that experience high (low) temperature trends and variability that are referred to as hot spots (cold spots). The upper Midwest …
