Homelessness In Portland, Oregon: An Analysis Of Homeless Campsite Spatial Patterns And Spatial Relationships, Krystle N. Harrell
Geography Masters Research Papers
Homelessness is a complex American social issue. Understanding the homeless population, including how many people experience homelessness, how they entered the experience, their demographics, how they survive, and where they survive, aids policymakers, planners, and advocates in developing the appropriate approaches and solutions to end and prevent homelessness. Analysis of homeless spatial patterns and distributions across different locales provides a more in-depth understandings of this population and how best to support them, from the local to national level. Using geographic information systems (GIS) and statistical methods, this study examines the spatial patterns of homeless campsites and their relationship with urban …

The Cost Of Hauling Timber: A Comparison Of Raster- And Vector- Based Travel-Time Estimates In Gis, Sara M. Loreno
Geography Masters Research Papers
The cost of transporting forest products from harvest site to processing facility is a critical indicator of timber project feasibility. In order to accurately assess these timber haul costs, least-cost travel-time estimates among the site and the facility can be estimated using vector- or raster-based GIS methods. This study explores the applicability of both the raster- and vector-techniques within a variety of landscapes, including forested areas where comprehensive transportation data is limited. A comparison between the travel-time estimates derived from both methods was performed on three study sites using real-world data. The comparison also tested the effect of resolution on …
