 Geospatial Research Scientists Ryan Williams and Daniel Lizzadro-McPherson, in collaboration with Dr. Don Lafreniere and Dr. Guy Meadows, presented their work to map historic rates of change along Lake Michigan’s shoreline, at the Lakebed 2030 Tech Surge conference. The event took place in October of 2019 in Traverse City. At the conference, Ryan and Daniel shared the latest technological advancements with Great Lakes communities and businesses, which are reliant on shoreline data to make important decisions that impact everyone living or working along the shore.
“A main component of these land use planning methods is an understanding of the history of shoreline and coastal bluff change over time. This project uses Geographic Information Systems (GIS) to map historic aerial images from 2016, 2009, 1980 and 1938 and used those images to create historic shoreline and bluff line features that could be used to visualize historic coastlines and characterize areas vulnerable to future shoreline change.” (1) Community Planning groups such as Networks Northwest and Land Information Access Association were in attendance and were aided by the creation of the Community Coastal Resiliency Strategy, and a GIS map and app containing imagery and maps of Great Lakes shorelines, bluff lines, and a 30-year bluff-retreat risk analysis. These groups and more have gained a new tool and insight which can be used to move business, and residential development, forward along Great Lakes shores. ***Financial assistance for this project was provided, in part, by the Michigan Coastal Zone Management Program, Michigan Department of Environment, Great Lakes, and Energy
