Using Drones To Generate New Data For Conservation Insights, Paul Lorah, Alice Ready, Emma Rinn 2018 University of Saint Thomas

Using Drones To Generate New Data For Conservation Insights, Paul Lorah, Alice Ready, Emma Rinn

International Journal of Geospatial and Environmental Research

Human impact on the environment is driving a decline in biodiversity that heightens the need for informed management of conservation lands. Unmanned aerial vehicles (UAVs), also known as drones, are an increasingly cost-effective tool for generating high-quality data used to map landscape features, analyze land cover change and assess the effectiveness of conservation efforts. Traditional sources of remotely sensed data such as satellites and aircraft can be costly, inflexible and unable to detect fine-scale surface variation. This paper explores the advantages (and challenges) of analyzing data collected by drones to generate useful conservation management insights. We focus on three key ...


Which Urban Residents Vote And Why? A Geospatial Analysis Of Voting Behavior In Worcester, Ma, John D. Holbrook 2018 Salem State University

Which Urban Residents Vote And Why? A Geospatial Analysis Of Voting Behavior In Worcester, Ma, John D. Holbrook

Graduate Theses

This study investigates the relationship between voter travel distance to polling places in Worcester, MA and voter turnout. Linear and geographically-weighted regression are used to evaluate the significance of travel distance and demographic control variables. Worcester appears to be unique when compared to previous studies investigating travel distance and voter turnout. Travel distance to polling place does not reliably predict voter turnout in Worcester, but vehicle ownership, race, and age do.

Geography Faculty Publications and Presentations

In recent decades large fires have affected communities throughout central and southern Chile with great social and ecological consequences. Despite this high fire activity, the controls and drivers and the spatiotemporal pattern of fires are not well understood. To identify the large-scale trends and drivers of recent fire activity across six regions in south-central Chile (~32–40° S Latitude) we evaluated MODIS satellite-derived fire detections and compared this data with Chilean Forest Service records for the period 2001–2017. MODIS burned area estimates provide a spatially and temporally comprehensive record of fire activity across an important bioclimatic transition zone between ...

The Building a Resilient Coast project seeks to provide stakeholders with easy access to information to facilitate planning for climate and hazards impacts.


Estimation Of The Relationship Between Satellite-Derived Vegetation Indices And Live Fuel Moisture Towards Wildfire Risk In Southern California, Kristen Whitney, Seung Hee Kim, Shenyue Jia, Menas Kafatos 2018 Chapman University

Estimation Of The Relationship Between Satellite-Derived Vegetation Indices And Live Fuel Moisture Towards Wildfire Risk In Southern California, Kristen Whitney, Seung Hee Kim, Shenyue Jia, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

Southern California possesses a Mediterranean climate having semi-arid to arid characteristics and contains shrubland areas at high risk to wildfire. To assess wildfire danger, fire agencies have been monitoring the moisture of vegetation, called live fuel moisture (LFM), using field-based sampling. Unfortunately, spatial and temporal resolution of live fuel moisture data are significantly limited because sampling is labor intensive. Remote sensing satellite data has been used to monitor vegetation moisture content and health of shrublands. Therefore, a potential approach to overcome the limitations of manual measurements of live fuel moisture is to use vegetation indices (VIs) derived from satellite data ...


The Energy Yield Of Global Crops 1961-2016, Quinn Montana 2018 University of Arkansas, Fayetteville

The Energy Yield Of Global Crops 1961-2016, Quinn Montana

Theses and Dissertations

It is often suggested that world food production must increase by 70%-100% or more by the year 2050 if we are to feed the anticipated world population at that time. To evaluate this claim, global crop production from 1961 to 2016 was inventoried using publicly available data from the United Nations Food and Agriculture Organization (FAO). To determine the adequacy of global crop output for humanity, annual global food crop production data (T y-1) were converted to energy yield in kilojoules (KJ y-1). These data were then compared to the annual metabolic energy requirement of the global human population ...


Humans As Sensors: The Influence Of Extreme Heat Vulnerability Factors On Risk Perceptions Across The Contiguous United States, Forrest Scott Schoessow 2018 Utah State University

Humans As Sensors: The Influence Of Extreme Heat Vulnerability Factors On Risk Perceptions Across The Contiguous United States, Forrest Scott Schoessow

All Graduate Theses and Dissertations

Extreme heat events are the deadliest natural hazard in the United States and will continue to get worse in the coming years due to the effects of climate change. As a result, more people will experience deadly heat conditions. This highlights the need for decision-makers to develop better strategies for preventing future losses. How badly individuals are affected by extreme heat depends on many circumstances, such as how high temperatures actually are, weather conditions, and location. For example, a dry 90 °F day in Phoenix is probably more tolerable than a humid 90 °F day in New Orleans for most ...


Critical Citizenship Education Through Geography, Jung Eun Hong 2018 University of West Georgia

Critical Citizenship Education Through Geography, Jung Eun Hong

International Journal of Geospatial and Environmental Research

In a current globalized world, citizens are expected and encouraged to understand cultural diversity and respect individual differences. Furthermore, they are also expected to become responsible citizens for recognizing and actively participating in issues on social justice and human rights at local to global scales. That is, our diverse society demands “critical” citizens who are interested in public affairs, concerned about inequality and injustice, and motivated to change and improve our society. In response to an increased need for actively engaged and participating citizens in a today’s world, critical citizenship education has been suggested as a new framework for ...

International Journal of Geospatial and Environmental Research

This research contributes an educational research perspective to teaching and learning with geospatial technologies. This work considers the literacy of a geospatial text that is readily accessible to students, but often assumed to be intuitive to read– dynamic scalable satellite imagery, which often serves as base maps for common navigation, GIS, and virtual globe applications. Within the context of a STEM project, Grades 5 and 6 students were observed and interviewed to identify knowledge and skills that were required to make meaning of Google Earth imagery. A qualitative methodological approach incorporating a thinkaloud data collection protocol was followed to stay ...


Improving Spatial Thinking Through Experiential-Based Learning Across International Higher Education Settings, Kyle C. Flynn 2018 Oklahoma State University - Main Campus

Improving Spatial Thinking Through Experiential-Based Learning Across International Higher Education Settings, Kyle C. Flynn

International Journal of Geospatial and Environmental Research

Research in geographic education has a strong focus on the improvement of spatial thinking. For Millennials, spatial thinking curriculum could benefit from the inclusion of experiential-based learning activities. However, as universities are faced with larger class sizes, new approaches need to be incorporated by the instructors to offer improved learning environments. Courses introducing basic geography skills often incorporate lessons concerned with spatial thinking and global perspectives. Thus, the instruction of geographic tools such as Global Positioning Systems (GPS), longitude, latitude, and remote sensing offer prime opportunities for experiential-based learning in geographic pedagogy. This research aimed to employ a low-cost experiential-based ...

International Journal of Geospatial and Environmental Research

The purpose of this research is to advance K-12 geospatial learning by investigating the methods (traditional paper versus digital technology) best suited for delivering content that improves spatial thinking skills. This research was designed to investigate whether instruction through different media, among other variables such as attitudes toward geography and technology, past travel experience, and demographic variables have an effect on the development of spatial thinking skills. Specifically, it examines traditional, paper aerial imagery as compared to digital imagery visualized with 3-D globes. Findings confirm that students taught by both paper and digital media showed improvement in spatial thinking skills ...


Role Of Geography Courses In Improving Geospatial Thinking Of Undergraduates In The United States, Kanika Verma, Lawrence Estaville 2018 N/A

Role Of Geography Courses In Improving Geospatial Thinking Of Undergraduates In The United States, Kanika Verma, Lawrence Estaville

International Journal of Geospatial and Environmental Research

This national study utilizes the Geospatial Thinking Survey (GTS) to assess the geospatial thinking abilities of undergraduates in the United States. A survey of 1479 students from 61 public universities provided the data. The mean score of geography majors was the highest, while that of criminal justice majors was the lowest. The mean score of students who studied at least three college geography courses was significantly higher than those students who took less than three college geography courses. College geography courses apparently bolster student geospatial thinking abilities, thereby corroborating the stronger geospatial thinking skills of geography majors. Moreover, individual questions ...


The Impact Of World War One On The Forests And Soils Of Europe, Jason Andrew Heiderscheidt 2018 University of Northern Colorado

The Impact Of World War One On The Forests And Soils Of Europe, Jason Andrew Heiderscheidt

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

The First World War was one of the deadliest conflicts in human history thus far. With the human toll being over eight million deaths, and millions more wounded, and as such it has taken hold in peoples imaginations for over a hundred years. However, one overlooked impact of the war is the environmental impact it had. The forests of Europe were significantly changed, going from being diverse ecosystems pre-war to monocultures after the war, dominated by single species of trees. The soil was also affected, more heavily in some places, becoming contaminated with heavy metals, as well as becoming entirely ...

Re-Reading The Map Of Middle-Earth: Fan Cartography's Engagement With Tolkien's Legendarium, Stentor Danielson 2018 Slippery Rock University of Pennsylvania

Re-Reading The Map Of Middle-Earth: Fan Cartography's Engagement With Tolkien's Legendarium, Stentor Danielson

Journal of Tolkien Research

J.R.R. Tolkien provided an elaborate textual history for his writings about Middle-earth, but did not do so for his now-iconic maps. This paper examines how this difference, in concert with the general tendency of readers to treat maps as objective records of geography, has manifested in Tolkien's work and fan works based upon it. An examination of fan cartography shows a strong tendency to treat the published maps as records of geographical fact rather than historical documents from within Middle-earth.

Development Of A Qgis Plugin To Dasymetric Mapping, Nelson Mileu, Margarida Queirós

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Demographic data is usually represented by choropleth map, where the statistical data is aggregated to areal units. This type of representation has several limitations associated with spatial analysis and distribution. A common alternative to display statistical data in meaningful spatial zones is the dasymetric mapping technique. Though dasymetric mapping has existed for many decades, the open source GIS tools to explore dasymetric mapping methods are scarce. In this paper, a Geographical Information System (GIS) open source application was developed in QGIS software that applies the dasymetric mapping method to the Portuguese Guimarães municipality 2011 Census block-group populations and using Corine ...

Crowdsourcing The Georeferencing Of Historical Pictures, Timothée Produit, Nicolas Blanc, Sarah Composto, Jens Ingensand, Loic Furhoff

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Countless organizations own archive pictures which are not used due to the difficulty of localizing them. Only the participation of volunteers can help to identify the image content. Through an accessible web interface called smapshot, citizens are able to georeference historical images without any prior specific competence. To avoid the volunteers to face the complexity of 3D digitization and navigation, we implemented a state of the art photogrammetry camera orientation algorithm in the platform. Currently several thousand images from all around Switzerland have been georeferenced by the crowd. At this time the tool is mainly used by the population for ...
