Seagrass, coastal land-use, and map-validation data for Kung Krabaen Bay, Thailand, 2016–2022

This dataset contains author-generated seagrass, coastal land-use, and map-validation data supporting a study of spatiotemporal seagrass dynamics in Kung Krabaen Bay, Thailand, during 2016–2022. The files include annual mapped class areas, zone-year seagrass and land-use variables, classification confusion matrices, and transition summaries. A README, data dictionary, class codebook, and file inventory are provided to support interpretation and reuse. Water-quality and sediment observations supplied by the Kung Krabaen Bay Royal Development Study Center are excluded because their reuse requires prior permission from the data provider. Consequently, this public dataset does not contain all inputs required to reproduce the environmental pathway and ordination analyses.
