Estimating Effects Of Tourism Using Multiple Data Sources: The Miranda Tool As Part Of A Spatial Decision Support System For Sustainable Destination Development, Tobias Heldt

GSTC Academic Symposium - In conjunction with the GSTC Global Conference Sweden April 23, 2024

Planning for sustainable mobility and destination development in rural areas is increasingly important when tourism grows in numbers. A key to address the challenge of transformation and adaptation of local communities to mitigate adverse effects in seasonal peak hours like traffic congestion, power failure, waste management and sewage flooding, is to properly estimate the number of visitors to a destination.

The problem of estimating tourism numbers is a known challenge since, for example, guest nights statistics are in-complete and non-commercial lodging (sharing solutions) are increasing. Recently, the promising utilization of mobile phone data has emerged as a means to estimate …

Streamlined Hpc Environments With Cvmfs And Cybergis-Compute, Alexander C. Michels, Mit Kotak, Anand Padmanabhan, Shaowen Wang

I-GUIDE Forum

High-Performance Computing (HPC) resources provide the potential for complex, large-scale modeling and analysis, fueling scientific progress over the last few decades, but these advances are not equally distributed across disciplines. Those in computational disciplines are often trained to have the necessary technical skills to utilize HPC (e.g. familiarity with the terminal), but many disciplines face technical hurdles when trying to apply HPC resources to their work. This unequal familiarity with HPC is increasingly a problem as cross-discipline teams work to tackle critical interdisciplinary issues like climate change and sustainability. CyberGIS-Compute is middle-ware designed to democratize to HPC services with the …

An Agent-Based Modeling Approach To Spatial Accessibility, Alexander C. Michels, Shaowen Wang

I-GUIDE Forum

Place-based spatial accessibility represents the ability of populations within geographic units to access goods and services, and thus is an important indicator for sustainable development. Existing spatial accessibility models treat population as simply demand, calculating statistics or optimizing average cost for the population within each geographic unit, rather than modeling individual decisions. This paper proposes AgentAccess, a general-purpose Agent-Based Model (ABM) for spatial accessibility analysis. An ABM framework brings us closer to reality by simulating individual and imperfect decision-making. We introduce the model and compare its results against existing spatial accessibility models using a case study of hospital beds in …

Reducing Uncertainty In Sea-Level Rise Prediction: A Spatial-Variability-Aware Approach, Subhankar Ghosh, Shuai An, Arun Sharma, Jayant Gupta, Shashi Shekhar, Aneesh Subramanian

I-GUIDE Forum

Given multi-model ensemble climate projections, the goal is to accurately and reliably predict future sea-level rise while lowering the uncertainty. This problem is important because sea-level rise affects millions of people in coastal communities and beyond due to climate change's impacts on polar ice sheets and the ocean. This problem is challenging due to spatial variability and unknowns such as possible tipping points (e.g., collapse of Greenland or West Antarctic ice-shelf), climate feedback loops (e.g., clouds, permafrost thawing), future policy decisions, and human actions. Most existing climate modeling approaches use the same set of weights globally, during either regression or …

Modeling Airport Catchment Areas: Using Spatial Analysis Approach, Sitong Chen

The Journal of Purdue Undergraduate Research

Th e airport catchment area is the geographic area from which an airport can reasonably expect to draw commercial air service passengers. Th e purpose of this interdisciplinary research is to estimate airport catchment areas using a spatial analysis method for informed airport management. In order to ensure the comprehensiveness and reliability of the research, we chose to analyze the catchment areas for five airports of different sizes and in different geographic locations in the United States. The Huff model, which is usually used in marketing, economics, and retail research, was adopted in this study. We applied this model in …

Effects Of Removing Background Soil Reflectance Pixels From Vegetative Index Maps For Characterization Of Corn Responses To Experimental Treatments, Ana Morales, Robert L. Nielsen, James J. Camberato

Purdue GIS Day

In contrast to traditional data collection methods that require manual sampling, vegetative index (VI) maps derived from unmanned aerial vehicles (UAV) imagery are a potential tool to characterize temporal and spatial treatment effects in a more efficient and non-destructive way. Remotely-sensed reflectance data from a growing corn crop contains pixel values associated with the above-ground plant tissue (e.g., leaves, stalks, tassels) and the underlying soil features. Background soil reflectance data potentially reduces the effectiveness of VI for characterizing crop responses to experimental treatments. Removing background soil image pixels from the larger image dataset should improve that effectiveness. The objective of …

Visualizing Election Results With Arcgis, Ryan Day

Purdue GIS Day

In 2018, Porter County, Indiana held its municipal elections concurrent with the national midterm elections. Using ArcGIS, the election results for the fourway race for the Duneland School Board at-large seat are mapped. These results are compared to other area election results, voter characteristics, and previous election results to try to visualize the correlation between factors affecting the race, including candidate ideology, geographic base, area demographics, turnout, and national electoral trends. This project serves as a demonstration of how GIS software can improve the understanding of what influences voters and election outcomes.

Soil Erosion Analysis Of The Monroe County’S Watersheds In Indiana, Danielli De Melo Moura, Jie Shan

Purdue GIS Day

This study was carried out to spatially predict the amount of soil loss (tons/ha/year ) of Monroe County’s watersheds using Geographic Information System (GIS). Revised Universal Soil Loss Equation (RUSLE) was used to estimate potential soil losses by using information such as rainfall data for calculating the rainfall erosivity (R) , soil map for calculating the soil erodibility (K), digital elevation model for obtaining the topography factor (LS) and vegetation/cropland cover for calculating the cover management factor (C) and support practice factor (P). The result of the analysis depicted that the soil loss rate in Moroe’s watersheds ranges from 0 …

Mapping Postcolonial Literature, Matthew Hannah, Yiqui Yan

Purdue GIS Day

Matthew Hannah (Assistant Professor of Digital Humanities) Yiqiu Yan (Undergraduate Researcher) Space and place are incredibly important features of the postcolonial novel and, for writers of the twentieth and twenty-first centuries who are living in former colonies, geography plays an incredibly significant role in navigating issues of identity, language, and nationality. Because the land is such a contested concept in postcolonial writing, we believe that attending to the localities described in literary representations of the land will provide a rich resource for theorizing the relationship between people and places, between colonies and nations. “Mapping Postcolonial Literature” will showcase an interactive …

Growth, Sprawl, And The Contradictions Of Capitalism: San Diego Suburbs And The Speculative Frenzy, 1970-1991, Richard Hogan

Purdue GIS Day

San Diego has become the most beautiful place where nobody can afford to live because speculative growth drives housing prices regardless of the level of supply or demand. How this happened in San Diego County is fairly clear. Marx explained that ground rents (and thereby land prices) increase when capital and labor are invested in the most valuable land and when investment is intensive, with vast amounts of labor and capital focused on the high yield properties to the virtual exclusion of less productive or less valuable lands. In fact, speculative growth between 1960 and 1980 conformed to what Marx …

Geoannotator: A Collaborative Semi-Automatic Platform For Constructing Geo-Annotated Text Corpora, Morteza Karimzadeh, Alan M. Maceachren

Purdue University Libraries Open Access Publishing Fund

Ground-truth datasets are essential for the training and evaluation of any automated algorithm. As such, gold-standard annotated corpora underlie most advances in natural language processing (NLP). However, only a few relatively small (geo-)annotated datasets are available for geoparsing, i.e., the automatic recognition and geolocation of place references in unstructured text. The creation of geoparsing corpora that include both the recognition of place names in text and matching of those names to toponyms in a geographic gazetteer (a process we call geo-annotation), is a laborious, time-consuming and expensive task. The field lacks efficient geo-annotation tools to support corpus building and lacks …

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 …

Economic Resilience And Concentration In Indiana Over 2002-2016, Santiago Ruiz, Michael Wilcox, Indraneel Kumar

Purdue GIS Day

It is well accepted that recessionary shocks affect long-term patterns of economic growth within regions. For this reason, it is important to understand how regional economies recover and in which extent a shock could be an economic burden in long term. A relevant variable to measure shock’s impact is employment, for two reasons. First, past recessions suggested that in most cases, the decline in employment tended to be deeper than in output. Second, layoffs of workers are key forms of adjustment to which employees seek to reduce costs. Given these, our research aims to understand shifts in employees during, after …

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 …

How Much Do Purdue's Trees Weigh? Estimating Biomass In Urban Areas, Jacob Klaybor, Gillian Clark, Brady Hardiman

Purdue GIS Day

Vegetation plays an important role in urban areas by reducing the urban heat island effect, sequestering carbon emissions, and providing socioeconomic benefits to the surrounding areas. However, the roles and distributions of urban forests have historically been ignored or underestimated. This presentation uses the campus of Purdue University in West Lafayette, IN, as a case study to quantify the aboveground vegetative biomass of campus trees. Tree biomass is calculated with data from the Purdue Arboretum and family-specific allometric relationships based on each tree's diameter at breast height to estimate the total carbon storage available within campus trees. Biomass estimates of …
