    • Timucuan Ecological and Historic Preserve Salt Marsh Classification

    Metadata Updated: June 5, 2024

    Loss of salt marsh habitat at Timucuan Ecological and Historic Preserve (TIMU) due to sea level rise has been identified by park staff as a concern. The purpose of this project is to classify and quantify the two dominant genera, Juncus and Spartina, of salt marsh grasses found within the preserve. These data can be used to calculate community changes from years past and into the future. Other classes such as water, trees, other upland vegetative communities, and salt flats were also quantified. Color infrared orthoimagery (2012), LiDAR data (2007), and Trimble eCognition software were used for this project to accomplish this object-based image analysis. This object-based technique groups neighboring homogeneous pixels and then uses contextual properties to enable the analyst to accurately classify a landscape.
