Measuring Building Height Using Point Cloud Data Derived From Unmanned Aerial System Imagery In An Undergraduate Geospatial Science Course, David L. Kulhavy, I-Kuai Hung, Daniel R. Unger, Reid Viegut, Yanli Zhang

Faculty Publications

The use of Unmanned Aerial Systems (UAS), also known as drones is increasing in geospatial science curricula within the United States. Within the Arthur Temple College of Forestry and Agriculture (ATCOFA) at Stephen F. Austin State University, Texas, seniors in the geospatial science program complete capstone projects to evaluate current geospatial technology to investigate complex ecological, social and environmental issues. Under the umbrella of a student initiated and designed senior project, students designed a study to estimate height of buildings with UAS data incorporating UAS data, LP360 and ArcScene programs, and Pictometry web-based interface. Results from a statistical analysis of …

Proving Our Maternal And Scholarly Worth: A Collaborative Autoethnographic Textual And Visual Storying Of Motherscholar Identity Work During The Covid-19 Pandemic, Elizabeth Spradley, Sarah S. Leblanc, Heather Olson-Beal, Lauren Burrow, Chrissy Cross

Faculty Publications

Pivoting to remote work as female academics and to schooling our children from home as mothers in March 2020 marked a dramatic shift in how we enact our MotherScholar identities. This collaborative autoethnographic study employs a modification of interactive interviewing and photovoice to produce verbal and visual text of COVID-19 MotherScholar identity work for analysis. Thematic analysis results in themes of maternal interruptions, professional interruptions, maternal recognition, and professional recognition. Of note, our MotherScholar interactivity functioned as identity work as we sought and granted legitimacy to one another’s’ COVID-19 MotherScholar identities. Of particular concern to us is how institutions of …

Student Led Area Measurement Assessments Using Virtual Globes And Pictometry Web-Based Interface Within An Undergraduate Spatial Science Curriculum, David Kulhavy, I-Kuai Hung, Daniel Unger, Yanli Zhang

Faculty Publications

The use of Virtual Globes and Pictometry continues to expand and develop in undergraduate spatial science education. Spatial science undergraduates measured the area of 30 rectangles on the earth’s surface and compared them to Pictometry hyperspectral imagery measurements within a web-based interface and the Google Earth interface compared to ArcGIS Explorer, Map Developers and ArcMap using the ArcMap 10.5.2 interface. An analysis of variance of the absolute mean area errors (p-value of 0.009271) concluded the accuracy of the five area measurements were statistically different at the 95% confidence interval. A Tukey pair-wise test found that the Pictometry and Google Earth …

Integrating Unmanned Aircraft Systems To Measure Linear And Areal Features Into Undergraduate Forestry Education, Reid Viegut, David Kulhavy, Daniel Unger, I-Kuai Hung, Brian Humphreys

Faculty Publications

The use of Unmanned Aircraft Systems (UAS) in undergraduate forestry education continues to expand and develop. Accuracy of data collection is an important aspect of preparation for "society-ready" foresters to meet the complex sustainable environment managing for ecological, social and economic interests. Hands-on use of a DJI Phantom 4 Pro UAS by undergraduates to measure the length and area of 30 linear features and areal features on Earth's surface were estimated. These measurements were compared (measured within the ArcMap 10.5.2 interface) to hyperspectral Pictometry imagery measured on the web-based interface and the Google Earth Pro interface. Each remotely estimated measurement …

The Role Of Hypermasculinity, Token Resistance, Rape Myth, And Assertive Sexual Consent Communication Among College Men, Autumn Shafer, Rebecca R. Ortiz, Bailey Thompson, Jennifer, Huemmer

Faculty Publications

Purpose

A greater understanding of how college men's gendered beliefs and communication styles relate to their sexual consent attitudes and intentions is essential within the shifting context of negative to affirmative consent policies on college campuses. The results of this study can be used to help design more effective sexual consent interventions.

Student Perceptions Of Engagement In A Mandatory Programatic Service Learning, Gina Fe Causin, Chay Runnels

Faculty Publications

In the hospitality industry, service-learning opportunities are particularly important for students seeking work in the meeting and event planning industry. Faculty of a hospitality program at a regional university in East Texas decided to investigate the benefits in embedding service learning activities to their hospitality courses. The study investigated student perceptions of their participation in compulsory service learning assignments were created and implemented. Service learning assignment benefited the respondents personally; it benefited the sponsoring organization; it benefited the respondents’ career goals and their own individual awareness of community issues.

Integrating Faculty Led Service Learning Training To Quantify Height Of Natural Resources From A Spatial Science Perspective, Daniel Unger, David Kulhavy, Kai Busch-Peterson, I-Kuai Hung

Faculty Publications

Arthur Temple College of Forestry and Agriculture (ATCOFA) faculty members were trained how to integrate service learning activities within senior level classes at Stephen F. Austin State University (SFASU) in Nacogdoches, Texas. The service learning training, taught under the acronym Mentored Undergraduate Scholarship (MUGS), involved meeting with fellow faculty members over the course of an academic year during the fall semester to first learn how to incorporate service learning activities in a senior level class followed by its incorporation into a class the following spring semester. The service learning model was applied to students in GIS 420, a senior level …

Incorporating Applied Undergraduate Research In Senior To Graduate Level Remote Sensing Courses, Richard Henley, Daniel Unger, David Kulhavy, I-Kuai Hung

Faculty Publications

An Arthur Temple College of Forestry and Agriculture (ATCOFA) senior spatial science undergraduate student engaged in a multi-course undergraduate research project to expand his expertise in remote sensing and assess the applied instruction methodology employed within ATCOFA. The project consisted of performing a change detection land-use/land-cover classification for Nacogdoches and Angelina counties in Texas using satellite imagery. The dates for the imagery were spaced approximately ten years apart and consisted of four different acquisitions between 1984 and 2013. The classification procedure followed and expanded upon a series of concrete theoretical remote sensing principles, transforming the four remotely sensed raster images …

Integrating Hands-On Undergraduate Research In An Applied Spatial Science Senior Level Capstone Course, David Kulhavy, Daniel R. Unger, I-Kuai Hung, David Douglass

Faculty Publications

A senior within a spatial science Ecological Planning capstone course designed an undergraduate research project to increase his spatial science expertise and to assess the hands-on instruction methodology employed within the Bachelor of Science in Spatial Science program at Stephen F Austin State University. The height of 30 building features estimated remotely with LiDAR data, within the Pictometry remotely sensed web-based interface, and in situ with a laser rangefinder were compared to actual building feature height measurements. A comparison of estimated height with actual height indicated that all three estimation techniques tested were unbiased estimators of height. An ANOVA, conducted …
