Building A Gis Model To Assess Agritourism Potential, Brian G. Baskerville
Building A Gis Model To Assess Agritourism Potential, Brian G. Baskerville
Department of Geography: Dissertations, Theses, and Student Research
Rural areas of the world are developing and implementing tourism programs to diversify and reinvigorate their local economies. Often, these programs focus on privately-held lands in largely agricultural regions. In some countries, tourism development strategies have combined agriculture and tourism to create a new industry – agritourism. This industry, although not new in the United States, is still in its nascent stages. Before starting an agritourism enterprise, farmers and ranchers must consider the various factors that will likely influence their potential for long-term success. These factors can be grouped into 1) farm-specific factors such as an operator’s personality or the …
Landfills – Territorial Issues Of Cities From North-East Region, Romania, Florin C. Mihai, Pavel Ichim
Landfills – Territorial Issues Of Cities From North-East Region, Romania, Florin C. Mihai, Pavel Ichim
Florin C MIHAI
Landfilling prevails in waste management options in Romania like others new EU members, being contrary to the concept of waste hierarchy promoted in recent years by EC. Waste disposal is done usually in non-compliant landfills and Government established a program to close these sites. This paper aims to analyse the transition from traditional waste management systems to an integrated system at national, regional and local scale. Assessment of landfills location based on buffer analysis (using GIS techniques) is made according to the proximity of five critical factors (CF) such as: residential area, industry & commercial units, agricultural lands, rivers & …
Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles
Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles
Masters Theses & Specialist Projects
Digital Elevation Models (DEMs) are digital representations of surface topography or terrain. Collection of DEM data can be done directly through surveying and taking ground control point (GCP) data in the field or indirectly with remote sensing using a variety of techniques. The accuracies of DEM data can be problematic, especially in rugged terrain or when differing data acquisition techniques are combined. For the present study, ground data were taken in various protected areas in the mountainous regions of Nepal. Elevation, slope, and aspect were measured at nearly 2000 locations. These ground data were imported into a Geographic Information System …
Analysis Of The Spatial And Temporal Dynamics Of Street Hawking: A Case Study Of The Accra Metropolitan Area, Alex Owusu Barimah, Stephen Abrokwah, Stephen Frimpong
Analysis Of The Spatial And Temporal Dynamics Of Street Hawking: A Case Study Of The Accra Metropolitan Area, Alex Owusu Barimah, Stephen Abrokwah, Stephen Frimpong
Stephen Frimpong
To the street hawker, it is a means of making a living but to the managers of the metropolis, street hawking is a menace. These differences in perception have led to a game plan tied to spatio-temporal diurnal traffic regimes. While the city authorities plan may be to evict the street hawkers, the plan of the hawkers is to outwit the city authorities through make-shift hawking patterns in order to make a living. The difference in the two positions can be characterized by the city manager’s need for clean and less congested city streets, and the hawker’s desire to sell …
Anthropology And Gis: Temporal And Spatial Distribution Of The Philippine Negrito Groups, Sabino G. Padilla Jr
Anthropology And Gis: Temporal And Spatial Distribution Of The Philippine Negrito Groups, Sabino G. Padilla Jr
Human Biology
The Philippine "negrito" groups comprise a diverse group of populations speaking over 30 different languages, who are spread all over the archipelago, mostly in marginal areas of Luzon Island in the north, the central Visayas islands, and Mindanao in the south. They exhibit physical characteristics that are different from more than 100 Philippine ethnolinguistic groups that are categorized as non-negritos. Given their numbers, it is not surprising that Philippine negritos make up a major category in a number of general ethnographic maps produced since the nineteenth century. Reports from various ethnological surveys during this period, however, have further enriched our …

Riga: A Rich Internet Geospatial Analytics Application For Area-Based Data, Tin Seong Kam
Research Collection School Of Computing and Information Systems
In this information age, more and more public statistical data such as population census, household living, local economy and business establishment are distributed over the internet within the framework of spatial data infrastructure. By and large, these data are organized geographically such as region, province as well as district. Usually, they are published in the form of digital maps over the internet as simple points, lines and polygons markers limited or no analytical function available to transform these data into useful information. To meet the analytical needs of casual public data users, we contribute RIGA, a rich internet geospatial analytics …
Mobile 2d And 3d Spatial Query Techniques For The Geospatial Web, Junjun Yin
Mobile 2d And 3d Spatial Query Techniques For The Geospatial Web, Junjun Yin
Doctoral
The increasing availability of abundant geographically referenced information in the Geospatial Web provides a variety of opportunities for developing value-added LBS applications. However, large data volumes of the Geospatial Web and small mobile device displays impose a data visualization problem, as the amount of searchable information overwhelms the display when too many query results are returned. Excessive returned results clutter the mobile display, making it harder for users to prioritize information and causes confusion and usability problems. Mobile Spatial Interaction (MSI) research into this “information overload” problem is ongoing where map personalization and other semantic based filtering mechanisms are essential …

Application Of Gis And Spatial Data Modeling To Archaeology: A Case Study In The American Southwest, Veronica Arias
Anthropology ETDs
One of the most important methodological advances in the archaeology of the past quarter century is the use of Geographic Information System (GIS) in archaeological research. Within this time frame, GIS has evolved from an emergent geospatial technology with limited mapmaking capabilities to a technology of choice for cultural resource managers, planners, and academic archaeologists alike. This dissertation examines the evolutionary trajectory and impact of GIS in the discipline since its introduction, and its potential to support new applications of GIS-driven innovation in archaeological research. As part of this project, two separate studies were conducted. The first study assessed adoption …

Change And Continuity: Euro-American And Native American Settlement Patterns In The St. Joseph River Valley, Allison M. Kohley
Change And Continuity: Euro-American And Native American Settlement Patterns In The St. Joseph River Valley, Allison M. Kohley
Masters Theses
In recent years there has been a particular interest in the fur trade and colonialism through identification and investigation of Fort St. Joseph. This fort was an 18th century French trading post in the St. Joseph River valley located in southwestern Michigan and northwestern Indiana. This study expands our current understanding of the change and continuity of the Euro- American and Native American settlement patterns in the valley during the periods immediately prior to, during, and after the abandonment of Fort St. Joseph through the use of geographic information systems (GIS) and statistical analyses.
Data Storage Alternatives For A Gridded Crop Disease Risk Forecasting System, Paul J. Roehsner
Data Storage Alternatives For A Gridded Crop Disease Risk Forecasting System, Paul J. Roehsner
Masters Theses
Three separate storage technologies able to serve gridded data were selected for comparison of performance in terms of providing speed and expandability to a crop disease forecasting system. The three storage technologies chosen were PostgreSQL (a relational database management system), MongoDB (NoSQL system), and netCDF files. Speed tests were performed for each by running two different crop disease risk forecasting models requiring data of different spatiotemporal resolutions. Multiple trials were done using different storage hardware. Systems were then qualitatively compared for expandability by noting the process involved in adding successive crop disease forecasting models.
It was found that due to …
Local Ideal Point Method For Gis-Based Multicriteria Analysis: A Case Study In London, Ontario, Xue Qin
Local Ideal Point Method For Gis-Based Multicriteria Analysis: A Case Study In London, Ontario, Xue Qin
Electronic Thesis and Dissertation Repository
GIS-based multicriteria analysis (GIS-MCA) is a procedure for transforming and combining geographic data and value judgments (preferences) to evaluate a set of alternatives with respect to relevant criteria. Ideal Point Method (IPM) is one of the most often used GIS-MCA techniques. It has been applied in many research/planning areas including environmental planning, urban/regional planning, waste management, water resource management and agriculture. One of the limitations of IPM is that it has conventionally been used as a global approach based on the implicit assumption that its parameters do not vary as a function of geographic space. The conventional IPM assumes a …

Site Location Modeling And Prehistoric Rock Shelter Selection On The Upper Cumberland Plateau Of Tennessee, Lucinda M. Langston
Site Location Modeling And Prehistoric Rock Shelter Selection On The Upper Cumberland Plateau Of Tennessee, Lucinda M. Langston
Electronic Theses and Dissertations
Using data collected from 2 archaeological surveys of the Upper Cumberland Plateau (UCP), Pogue Creek Gorge and East Obey, a site location model was developed for prehistoric rock shelter occupation in the region. Further, the UCP model was used to explore factors related to differential site selection of rock shelters. Different from traditional approaches such as those that use (aspatial) logistic regression, the UCP model was developed using spatial logistic regression. However, models were also generated using other regression-based approaches in an effort to demonstrate the need for a spatial approach to archaeological site location modeling. Based on the UCP …

Object-Based Urban Building Footprint Extraction And 3d Building Reconstruction From Airborne Lidar Data, Ting Zhao
Electronic Thesis and Dissertation Repository
Buildings play an essential role in urban intra-construction, urban planning, climate studies and disaster management. The precise knowledge of buildings not only serves as a primary source for interpreting complex urban characteristics, but also provides decision makers with more realistic and multidimensional scenarios for urban management. In this thesis, the 2D extraction and 3D reconstruction methods are proposed to map and visualize urban buildings. Chapter 2 presents an object-based method for extraction of building footprints using LiDAR derived NDTI (Normalized Difference Tree Index) and intensity data. The overall accuracy of 94.0% and commission error of 6.3% in building extraction is …

Urban Growth Patterns And Effectiveness Of The Metropolitan Urban Service Areas In Woodbury, Minnesota, Danielle Thomas
Urban Growth Patterns And Effectiveness Of The Metropolitan Urban Service Areas In Woodbury, Minnesota, Danielle Thomas
All Graduate Theses, Dissertations, and Other Capstone Projects
This study evaluates the effectiveness of a specific urban sprawl containment strategy called the Metropolitan Urban Service Areas (MUSA). MUSA was developed for Minneapolis/St. Paul in order to ensure organized and practical development in areas that already had pre-built roads and sewer system infrastructures. Currently, MUSA is not an urban boundary; its specific goal is to, "synchronize urban growth with the provision of infrastructure needed to accommodate growth" (Council, August 2006). To evaluate the rigidity of the MUSA boundaries, the sample years of 1990, 2000, 2010 and the projected 2020 boundaries were subjected to spatial analysis utilizing three different software …
A Study Of Habitat Selection By Blanding's Turtles (Emydoidea Blandingii) In Dutchess County, New York, Shannon Rauch
A Study Of Habitat Selection By Blanding's Turtles (Emydoidea Blandingii) In Dutchess County, New York, Shannon Rauch
Legacy Theses & Dissertations (2009 - 2024)
The Blanding's turtle (Emydoidea blandingii) is a New York State-listed threatened species with several disjunct populations located throughout the state. Blanding's turtles require a variety of habitat types including ponds, wetlands, vernal pools, and the surrounding uplands. Preserving these habitat complexes is necessary to ensure the persistence of Blanding's turtle populations, but this is becoming increasingly challenging in some locations due to significant development pressure. Key components of habitat protection are identifying preferred habitat types and gaining a better understanding of the variables that influence habitat selection. Previous landscape-level studies of turtles have found that land cover type, wetland type, …
