Analysis Of Interdunal Wetlands And Ecosystem Dynamics Using Uas And Obia In Ludington State Park, Michigan, Claire Gilbert
Analysis Of Interdunal Wetlands And Ecosystem Dynamics Using Uas And Obia In Ludington State Park, Michigan, Claire Gilbert
Masters Theses
The Great Lakes sand dunes are the world's largest freshwater dune complex. There is a functional relationship between coastal wetlands and freshwater sand dune, referred to as interdunal wetlands. Interdunal wetland systems are highly dynamic and change dramatically seasonally and annually. Using geographic information systems (GIS) and unoccupied aerial systems (UAS), this thesis project is focused on understanding the spatial distribution of sparse and dense vegetation, and abiotic influence such as distance to coast, slope, and aspect influence interdunal wetland stability within a Great Lakes shoreline dune system. Object-based image analysis (OBIA) classification results extracted meaningful vegetation densities of growth …
Using Historical Maps For Contaminated Site Identification And Prediction, And Environmental Justice Implications: A Case Study In Grand Rapids, Michigan, Dana Heusinkveld
Using Historical Maps For Contaminated Site Identification And Prediction, And Environmental Justice Implications: A Case Study In Grand Rapids, Michigan, Dana Heusinkveld
Masters Theses
As the production of synthetic chemicals has grown in the past centuries to increase production, lower costs, and generally make our lives more convenient, detecting and understanding the environmental impacts of these compounds has lagged significantly behind their mass production and wide-spread use. To combat this trend, sources of these contaminants, especially those that have been removed from the landscape, need to be quickly identified to make mitigation and remediation efforts more effective. In this study, historical Sanborn maps are used to extract and digitize historical site/land use in Grand Rapids during the early 1900s through the practical application of …
Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu
Spatial Discrepancies Between Nhdplus And Lidar-Derived Stream Networks, Nicole Marie Samu
Masters Theses
Many organizations demand that current water resource issues necessitate improved stream network mapping for more accurate and reliable watershed analysis and modeling results, which can ultimately enable better management and policy decisions. Stream network data from the National Hydrography Dataset Plus (NHDPlus) and derived from Light Detection and Ranging (LIDAR) are each widely accepted to be of superior quality compared to many other conventional datasets. Each dataset indicates potential to improve a wide range of water resource applications; NHDPlus for its high spatial accuracy and functionality, and LIDAR-derived networks for their high resolutions. NHDPlus is publicly available and widely used; …
