A “First And Last-Mile” Assessment Of California Rail Stations: A Sketch Planning Approach, Henry Mckay

City and Regional Planning

The purpose of this study is to assess the pedestrian and bicycle accessibility of rail stations in California by providing a sketch planning toolkit enabling planners and decision-makers to compare various accessibility factors and to develop and compare metrics.

Pedestrian and Bicycle Accessibility is a highly important area of transportation planning, especially as it pertains to rail stations. While a well-planned rail network can serve many people, travelers must get to and from rail stations on either end of their trip in order for the rail service to be of any use. The mode by which travelers make these trips …

Temporal Changes To Fire Risk In Disparate Wildland Urban Interface Communities, Nicola C. Leyshon

Master's Theses

Since 1990, thirteen fires over 100,000 acres in size have burned in California seven of which were recorded to be some of the most destructive wildfires of all time (California Department of Forestry & Fire Protection 2013). To aid the development of policy that reduces the destruction caused by wildfires, it is important to evaluate how risk changes through time in communities that are expanding into fire-prone areas. The objective of this study is to discover how the likelihood of structural loss is changing in WUI as newer; more fire resilient structures replace older structures on the edges of the …

A Spatial Analysis Of Crime In The City Of San Luis Obispo Using Free And Open Source Gis Software, Chad Bunn

Social Sciences

A study of crime in the City of San Luis Obispo using FOSSGIS programs including CartoDB and QGIS. The study was for the perio of January 1, 2012 through June 30, 2013.

Risk Assessment Model For Pipe Rehabilitation And Replacement In A Water Distribution System, Jan C. Devera

Master's Theses

The efficient delivery of potable water for a community through its distribution system has historically been the backbone of nearly all metropolitan developments. Much of these systems are comprised of pipe networks made of various materials including concrete, iron, PVC, and even steel. As these communities expand and urbanize, water demand and population density simultaneously increase. This develops higher strains and stresses in the community‟s water distribution network causing pipes to corrode, crack, or rupture prematurely while in service. As a result, the deterioration of water distribution systems in growing cities is increasingly becoming a major concern for our nation. …

Habitat Type Mapping In Montana De Oro State Park Through Gis Image Classification, Evan Corrales, Sarah Fockler

Natural Resources Management and Environmental Sciences

This project involved using aerial imagery and GIS procedures to automatically map the basic vegetation communities present within Montana de Oro State Park, CA: grassland, coastal scrub, bare ground, woodland, and riparian areas. 1m resolution color imagery of the park from the NAIP 2005 (National Agriculture Inventory Program) and 1m resolution LiDAR height data were also used to determine the locations of the different vegetation types in the park. This data was then classified by color using the interactive supervised classification tool in ArcGIS. Points were taken in the park using a GPS unit, and compared with the GIS results …

Geographic Information Systems Analysis Of Crime In San Luis Obispo For 2012, Eric Delorme

Social Sciences

The research and final project that I plan to do will be composed of a few different parts. I will be taking crime report data from the city of San Luis Obispo and analyzing it with GIS software. The data will be from the most recent reported calendar year. I will be looking at the data spatially so that I can compare the areas of the city in which crime is most prevalent. I will be creating multiple maps which will be looking individually at different types of crime, such as violent crimes, burglary and theft, assault and battery, sex …

A Discussion Of Factors Involved In The Formation Of Slab Avalanches And An Analysis Of Avalanche Risk In The Sierra Nevada Mountains Using Gis, Kevin C. Howen

Natural Resources Management and Environmental Sciences

As winter recreational activities increase in mountainous environments, the need for a better understanding of snow avalanches is necessary. This project consists of a study into the physical factors that contribute to slab avalanche formation, and a GIS analysis of an avalanche prone area within the Sierra Nevada Mountains. The primary physical factors that contribute to the conditions that lead to avalanches include the slope of a mountain face, the aspect, and bare ground conditions lacking thick forest vegetation. ArcGIS is a powerful software tool that was used to map each of these factors, and then combine them to create …

Accuracy Of Forest Road And Stream Channel Characteristics Derived From Lidar In Forested Mountain Conditions, Russell Alan White

Master's Theses

Forest roads and stream channels are mapped using a variety of remote sensing and ground-based techniques. In densely forested areas, conventional remote sensing methods provide limited terrain information, while ground-based surveys can be time-consuming, difficult, and expensive. Light Detection and Ranging (LiDAR) is an airborne remote sensing technology used to create high-resolution digital elevation models (DEMs) of the earth’s surface. This study tests the accuracy of forest road and stream channel features mapped using LiDAR in the steep, forested terrain of California’s Santa Cruz Mountains. A conventional total station survey was used to determine centerline position and elevations along a …
