Accuracy Assessment Of Pictometry® Height Measurements Stratified By Cardinal Direction And Image Magnification Factor, Daniel Unger, David Kulhavy, I-Kuai Hung, Yanli Zhang
Accuracy Assessment Of Pictometry® Height Measurements Stratified By Cardinal Direction And Image Magnification Factor, Daniel Unger, David Kulhavy, I-Kuai Hung, Yanli Zhang
International Journal of Geospatial and Environmental Research
The aim of this project was to ascertain if Pictometry® estimated height could be used in lieu of field-based height estimation. Height of a light pole measured with a telescopic height pole was compared to Pictometry® hyperspatial 4-inch (10.2 centimeters) multispectral imagery estimated light pole height on the campus of Stephen F. Austin State University, Nacogdoches, Texas. Average percent agreement between light pole height and Pictometry® estimated light pole height summarized by Pictometry® image magnification factors at 100%, 125%, 150%, 200%, and 300% magnification were within 98% of light pole height with percent disagreement ranging from …
Comparing Remotely Sensed Pictometry® Web Based Slope Distance Estimates With In Situ Total Station And Tape Slope Distance Estimates, David L. Kulhavy, Daniel R. Unger, Yanli Zhang, Phillip Bedford, I-Kuai Hung
Comparing Remotely Sensed Pictometry® Web Based Slope Distance Estimates With In Situ Total Station And Tape Slope Distance Estimates, David L. Kulhavy, Daniel R. Unger, Yanli Zhang, Phillip Bedford, I-Kuai Hung
International Journal of Geospatial and Environmental Research
Slope distance was measured between the top of 30 light poles and their respective ground level coordinate identified within a central parking lot on the campus of Stephen F. Austin State University, Nacogdoches, Texas. Slope distance measured using Pictometry® hyperspatial 4-inch (10.2 centimeters) multispectral imagery within a web based interface was compared to in situ total station and tape measured slope distance. The range for mean slope distance for Pictometry®, total station, and tape measured slope distance was 0.05 meters. Mean slope distance was 15.36 meters, 15.37 meters, and 15.41 meters for Pictometry®, total station, …
The Use Of Middle School Atlases In The Social Studies Classroom In South Korea, Jung Eun Hong, Hyoun Kyoung Lee
The Use Of Middle School Atlases In The Social Studies Classroom In South Korea, Jung Eun Hong, Hyoun Kyoung Lee
International Journal of Geospatial and Environmental Research
Middle school atlases are supplementary textbooks for social studies learning in South Korea. Although atlases are developed and designed to provide various useful resources for students’ social studies learning, especially geography, atlases have not been frequently used in actual social studies classrooms, and sometimes they are never used. This study reports the causes of low adoption rates of middle school atlases in Korean social studies classrooms through the analysis of survey responses from both teachers and students. This study also addresses ways of increasing the use of atlases in the classroom.
Crowdfunding And Crowdsourcing Initiatives In Detroit, Madhuri Sharma, Brenna Elrod
Crowdfunding And Crowdsourcing Initiatives In Detroit, Madhuri Sharma, Brenna Elrod
International Journal of Geospatial and Environmental Research
This study examines the role of crowdfunding and community-based initiatives in Detroit, a city that has been hurt by economic distress for several years. We start by compiling the Kickstarter projects initiated and successfully funded all over the US during April 2009-July 2012, and later focus on those occurring in Detroit only. We conduct in-depth analyses to understand the intra-urban characteristics that provide opportunities for such initiatives. By combining the census demographic data with qualitative information collected from online surveys and semi-structured interviews, we analyze the specific roles of crowdfunding initiatives in creating sustainable urban communities. This analysis finds that …
