Environmental and managerial factors associated with pack stock distribution in high elevation meadows: Case study from Yosemite National Park

Continuous 1985-2012 Landsat Monitoring to Assess Fire Effects on Meadows in Yosemite National Park, California

To assess how montane meadow vegetation recovered after a wildfire that occurred in Yosemite National Park, CA in 1996, Google Earth Engine image processing was applied to leverage the entire Landsat Thematic Mapper archive from 1985 to 2012. Vegetation greenness (normalized difference vegetation index (NDVI)) was summarized every 16 days across the 28-year Landsat time series for 26 meadows. D...

Software Visualization and Yosemite National Park

As software systems grow in size and complexity, so does the di culty of understanding and maintaining them. Research in software understanding attempts to mitigate this problem by making various aspects of software development more visible, accessible, and comprehensible. In this paper we propose a hypertext-based approach to software visualization in which navigation in software-space is mode...

Georeferencing Incidents from Locality Descriptions and its Applications: a Case Study from Yosemite National Park Search and Rescue

The Search and Rescue (SAR) of individuals who become lost, injured, or stranded in wilderness presents a unique and worthwhile spatiotemporal challenge to investigate. Once incidents are georeferenced they can be spatially queried and analyzed. However, one major challenge for evaluating SAR in a spatial context is the lack of explicitly spatial data (addresses or coordinates) for historic inc...

Transportation, Recreation, and Capacities in Yosemite National Park

Peak-season visitors to Yosemite Valley know first-hand that use levels can affect the quality of their experiences in the park. The sheer volumes of vehicles and people sometimes produce long lines at entrance gates, traffic jams at intersections, full parking lots, and congested trails or viewpoints. These problems have been challenging the park's infrastructure and operational staff for deca...
