Mapping the shoreline is one way Reserve staff uses GIS technology to monitor coastal processes and guide management activity. Each year, staff collect GPS locations along the vegetation line to map dynamic coastal areas such as Keewaydin Island.
Although Keewaydin Island has changed significantly over the years, our 2019 data shows little change. The island eroded 450 feet after Hurricane Irma and it hasn’t accreted back yet as shown by the 2019 shoreline. Historically, this map shows some considerable accretion, meaning that the island is growing longer from year to year.
