330— Spatial Trends Of Green Burial Grounds, U.S., Emma Ranney Apr 2021

330— Spatial Trends Of Green Burial Grounds, U.S., Emma Ranney

GREAT Day Posters

"Green" burial was the standard form of interment in the United States prior to the late 1800s. During the Civil War, the rate of chemical embalming grew out of necessity, as the deceased often had to be transported considerable distances to arrive in their home state. Chemical embalming quickly became one of the most common and accepted funeral practices in the nation. In 1993, however, the natural burial movement began in the U.K., and by 1998, the U.S. had its first green-burial-friendly cemetery. The purpose of this project is to analyze spatial, temporal, and additional significant trends regarding green burial …

Who Bears The Burden? Racial Disparities In Confirmed Cases Of Covid-19 In The Greater Boston Area, Leija Helling Dec 2020

Who Bears The Burden? Racial Disparities In Confirmed Cases Of Covid-19 In The Greater Boston Area, Leija Helling

Massachusetts GIS Day

Documenting racial disparities in the spread of COVID-19 is crucial to bettering public health. In the Boston area, non-white and Black communities are significantly overrepresented in areas of high confirmed COVID-19 prevalence. Areas where high prevalence is clustered (“hot spots”) have disproportionate shares of non-white and Black residents, and the disparities are statistically significant. These results confirm marked COVID-19 racial disparities in Boston.

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 Nov 2019

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 …
