Considering The Non-Programming Geographer's Perspective When Designing Extracurricular Introductory Computer Programming Workshops, Thomas R Etherington Dec 2018

Considering The Non-Programming Geographer's Perspective When Designing Extracurricular Introductory Computer Programming Workshops, Thomas R Etherington

Journal of Spatial Information Science

Computer programming is becoming an increasingly important scientific skill, but geographers are not necessarily receiving this training as part of their formal education. While there are efforts to promote and support extracurricular introductory computer programming workshops, there remain questions about how best to deliver these workshops. Therefore, as part of a recent introductory programming extracurricular workshop I organized for non-programing geographers, I tried to understand more about their perceptions of computer programming. I identify that one of the most important aspects for geographers to learn to computer program is to have training that is domain specific to ensure that the ...

Understanding Micro-Spatial Crime Patterns: A Comprehensive Trajectory Analysis Of Violent Crime At Street Segments In St. Louis, Mo, Aaron Levin Nov 2018

Understanding Micro-Spatial Crime Patterns: A Comprehensive Trajectory Analysis Of Violent Crime At Street Segments In St. Louis, Mo, Aaron Levin

Dissertations

Spatial crime studies have existed for over a century, but the last 20 years have seen a turn in focus toward micro-spatial units such as street blocks and street segments. A particular subfield of this modern micro-spatial perspective is called crime trajectory analysis, which can isolate patterns of crime at small spatial units over time. Though several crime trajectory analyses have been conducted for coastal cities, the technique has never been applied to Midwestern data. This project fills that research gap by using the group-based trajectory modeling (GBTM) algorithm to uncover patterns of violent crime at street segments in St ...

Is Corruption Influenced By Human Development Index And Transparency? A Global Spatial Assessment Using Gis, Seyedali Ghahari, Shabnam Ghotbi, Samuel Labi, Nader Naderpajouh

Purdue GIS Day

The intricacy of the construction practices sometimes causes the vague atmosphere between clients, partners, and providers, is one of the Achilles heels of infrastructure projects; this grounds the industry as the most inefficient, corrupted business in the world. Governments, in recent years, have made a significant positive effort on public transparency. E-government is an effective tool to execute the very subject. Not only e-government helps transparency, but also it provides openness, accountability, the participation of citizens, etc. By giving citizens access to the functionality of public organizations and institutions, and providing open media for public debates, nations can obtain higher ...


Gis To Address Questions In Forest Ecology And Management, Nicolas Picard Nov 2018

Gis To Address Questions In Forest Ecology And Management, Nicolas Picard

Purdue GIS Day

Geographic Information Systems (GIS) are powerful tools to deal with spatialized issues. As such, they have become routine tools in forestry to delimit forest resources, support the design of forest inventories, map forest resources, and analyze, model and support decision making to sustainably manage forests. Two examples will be provided to show how forest management can benefit from progress in GIS technology. The first one deals with the optimization of forest roads to harvest trees in tropical rainforests. It required the development of heuristics to solve the multiple target access problem in a reasonable time. The second one deals with ...

Modeling Sound In Ancient Maya Cities: Moving Towards A Synesthetic Experience Using Gis & 3d Simulation, Graham Goodwin Aug 2018

Modeling Sound In Ancient Maya Cities: Moving Towards A Synesthetic Experience Using Gis & 3d Simulation, Graham Goodwin

Anthropology Department Theses and Dissertations

Digital technologies enable modeling of the potential role of sound in past environments. While digital approaches have limitations in objectively rendering reality, they provide an expanded platform that potentially increases our understanding of experience in the past and enhances the investigation of ancient landscapes. Digital technologies enable new experiences in ways that are multi-sensual and move us closer toward reconstructing holistic views of past landscapes. Archaeologists have successfully employed 2D and 3D tools to measure vision and movement within cityscapes. However, built environments are often designed to invoke synesthetic experiences that also include sound and other senses. Geographic Information Systems ...

Native American Occupation Of The Singer-Hieronymus Site Complex: Developing Site History By Integrating Remote Sensing And Archaeological Excavation, Claiborne Sea

Electronic Theses and Dissertations

Located on a ridgetop in central Kentucky, the Singer-Hieronymus Site Complex consists of at least four Native American villages. The Native Americans who lived there are called the “Fort Ancient” by archaeologists. This study examined relationships between these villages, both spatially and temporally, to build a more complete history of site occupation. To do this, aerial imagery analysis, geophysical survey, and archaeological investigations were conducted. This research determined there were differences among villages in terms of their size, however other characteristics—internal village organization, village shape, radiometric dates, and material culture—overlapped significantly. Additionally, landscape-scale geophysical survey identified at least ...


A Spatial And Temporal Analysis Of San Juan Red Ware, Robert Jacob Bischoff Aug 2018

A Spatial And Temporal Analysis Of San Juan Red Ware, Robert Jacob Bischoff

Theses and Dissertations

San Juan Red Ware was widely distributed throughout the Four Corners region of the U.S. Southwest between about AD 750 and 1100. Prior research indicates this ware is a marker of identity and was likely associated with feasting and other communal activities. A study of the distribution of this ware indicates that it was traded widely, but with significant variation in relative quantity between sites. This variation is likely caused by unequal access to this ware due either to a lack of access to the necessary exchange networks or by a conscious decision to not participate in the exchange ...


Automating Wetland Prioritization Analyses Using Gis, Blythe Hawley Spendlove Jul 2018

Automating Wetland Prioritization Analyses Using Gis, Blythe Hawley Spendlove

MS GIS Program Major Individual Projects

In environmental and conservation fields, managers and other decision makers need to prioritize their efforts to specific areas using multiple-criteria decision analysis, to maximize environmental protection given limitations of budget and time. However, creating these prioritization models requires a combination of both scientific and technical skills, and many of those with the expertise to create scientifically sound prioritization models have limited time to devote to the technical aspects of the analysis. There was a need to automate this analysis process to enable scientists and other decision makers to quickly repeat analyses with different criteria and compare the results.

Aim: This study used both high resolution and medium resolution satellite imagery to test three semi-automated remote sensing methods, in an attempt to identify useful tools to support eye-witness testimony and reports on human rights violations. As huts are routinely burned down during attacks on a village, particularly in Sudan, the number of huts and villages burned can be used to corroborate on-the-ground reports.

Methods: Three remote sensing methods (Supervised Classification, Change Detection, and Feature Extraction) were performed on imagery from both before the attacks in February 2006 and after the attacks to examine any useful trends that could be ...


Spatial And Temporal Distribution Of Total Phosphorus Concentration In Soil And Surface Water In The Everglades Protection Area, Shishir Kumar Sarker Jun 2018

Spatial And Temporal Distribution Of Total Phosphorus Concentration In Soil And Surface Water In The Everglades Protection Area, Shishir Kumar Sarker

FIU Electronic Theses and Dissertations

Draining of the Everglades allowed for the expansion of urban and agricultural development, reducing half of the size of the historic Everglades. The detrimental cascading effect on the Everglades ecosystem function is related to the total phosphorus (TP) concentrations of water inflow, the inflow rate and the distance from the discharge point. As Everglades restoration has approached 15 years since the inception of the Comprehensive Everglades Restoration Plan (CERP), there is a need to assess its progress across the ecosystem. Available data from 2004 to 2014 were collected for soils and from 2004 to 2016 for water to understand a ...

In addition, the paper includes calculations for the average share of unused land in the ...


Election Administration Within The Sphere Of Politics: How Bureaucracy Can Facilitate Democracy With Policy Decisions, Nicholas S. Martinez May 2018

Election Administration Within The Sphere Of Politics: How Bureaucracy Can Facilitate Democracy With Policy Decisions, Nicholas S. Martinez

FIU Electronic Theses and Dissertations

Public bureaucracy finds itself in a strange place at the intersection of political science and public administration. Political science finds that, within representative democracy, discretion granted to bureaucrats threatens the nature of democracy by subverting politicians who represent the will of the people – bureaucracy vs democracy. At the same time, public administration holds that, in the interest of promoting democracy, bureaucracy should be objective in its implementation of policy in a way that eliminates the influence of politics from decision-making – politics vs bureaucracy. Those positions are seemingly contradictory in nature. From one perspective, bureaucracy is undemocratic because it is outside ...

Identifying Sinkholes Using A Geographic Information System (Gis), Andrew Kita May 2018

Identifying Sinkholes Using A Geographic Information System (Gis), Andrew Kita

Senior Honors Theses

Sinkholes are closed depressions in soil or bedrock that form through chemical dissolution of carbonate rock in karst regions. Several studies have identified geologic and hydrologic features that promote sinkhole formation and influence their spatial distribution. This study used a GIS to analyze the relationships between sinkholes and proximity to faults, proximity to streams, and soil thickness in Genesee County, NY. It was hypothesized that a higher frequency of sinkholes (more than half of the number of sinkholes) would occur 1,000 meters or less from a fault, 150-450 meters from a stream, and in areas with one meter or ...
