Human-Centered Avalanche Susceptibility Mapping, Lindsey L. Rotche Jul 2022

Human-Centered Avalanche Susceptibility Mapping, Lindsey L. Rotche

Geography ETDs

With backcountry winter travel increasing in popularity, the importance of accessible avalanche safety information is crucial. Widely accessible avalanche backcountry maps use slope shading to show where avalanches are likely to start. Instead of focusing on the hazard of an avalanche starting in a specific location, this project shifted the cartographic emphasis of avalanche susceptibility maps to show risk to a human traveling in the terrain. I developed a methodology to incorporate possible avalanche runouts, terrain traps, and connected slopes while reducing false certainty of the visualization. To provide a more comprehensive representation of susceptible terrain, I integrated aspect, distance …


Individual Exposure Potential Assessment For Livestock Based On Spatial-Temporal Analysis Of Gps Data And Behavior Patterns Classification In Cove Wash Watershed, Arizona, Zhuoming Liu Jun 2021

Individual Exposure Potential Assessment For Livestock Based On Spatial-Temporal Analysis Of Gps Data And Behavior Patterns Classification In Cove Wash Watershed, Arizona, Zhuoming Liu

Geography ETDs

This thesis examined the geospatial and temporal grazing patterns of domesticated livestock to model individual-level exposure potential to abandoned uranium mine (AUM) waste in a tribal community in the Southwest United States. Lotek Litetrack Global Positioning System (GPS) collars collected data at 20-minute-intervals for 2 flocks of sheep and goats during the Spring and Summer of 2019. Depending on the flock and individual animals, tracking time ranges from 10 days to four months. This research developed a GIS-based exposure potential framework that built on existing methodologies in time geography, GIS, and exposure mapping. This thesis aims to: 1) classify GPS …


A Hybrid Gis/In Situ Analysis Of Aed Coverage On The Unm Central Campus, Ian T. Hill Jul 2019

A Hybrid Gis/In Situ Analysis Of Aed Coverage On The Unm Central Campus, Ian T. Hill

Geography ETDs

Automated External Defibrillators (AED’s) are lifesaving devices that can greatly improve the survival rates of cardiac arrest when used quickly. There are publicly accessible AED’s on the UNM campus, and each device has an effective range based on how quickly a responder can retrieve the AED and return it to the site of the cardiac emergency. The ranges of the AED’s on UNM central campus are analyzed using GIS, interior building measurements, and various retrieval speeds. This helps evaluate the current placement of AED’s on campus and helps reveal where future coverage is needed. This focus on the combined navigation …


Assessing How Terrain Representations And Scale Affect The Accuracy Of Distance Estimates, Kristian Mueller May 2019

Assessing How Terrain Representations And Scale Affect The Accuracy Of Distance Estimates, Kristian Mueller

Geography ETDs

Terrain is often displayed on maps either as background or foreground. Although terrain representations are ubiquitous, there is not a thorough understanding of map-readers’ cognition of geographic surfaces from various terrain representations. The research described in this thesis empirically assessed map users’ abilities at estimating straight-line distance using maps with two different types of terrain representations and at three different scales. The objective of this research was to assess how accurately map users estimate distance on the ground taking into account variations in elevation. Participant data in the form of demographics and distance estimates were statistically analyzed to determine if …


Impact Of Drought On Land Cover Changes In Diné Bikéyah – A Study Through Remote Sensing, Anjanette A.J. Hawk Jan 2018

Impact Of Drought On Land Cover Changes In Diné Bikéyah – A Study Through Remote Sensing, Anjanette A.J. Hawk

Geography ETDs

This study identifies land cover changes associated with a ten-year drought period and discusses the importance of vegetation change in Diné Bikéyah, a semi-arid land located in a remote part of the southwestern United States (US). This study concludes that drought produced slight changes in vegetation within a 540 km2 study area in the Tselani-Cottonwood Chapter (TCC) in Diné Bikéyah. The data for this study consist of three Landsat images for the years 1998, 2002, and 2009. The methods used to analyze these Landsat images included image pre-processing, calculation of normalized difference vegetation index (NDVI) images, and supervised (maximum …
