Advancing Capacity for Marsh Modeling Retrospective Analysis

Elevation Mapping via Remote Sensing in Low Gradient Coastal Landscapes

Jan 31, 2026

This study was conducted by The Water Institute (the Institute) for the Gulf of Americal Alliance (GOAA) as a component of efforts to develop the data foundation for retrospective numerical modeling in coastal marshes. The report is a deliverable of the “Advancing Capacity for Marsh Modeling Retrospective Analyses in the Gulf of Mexico” project under subgrant FG-122347. The project manager for GOAA was Kate Harrison. Christopher Esposito led the execution of this task and the writing of the report for the Institute. This report describes the development and implementation of a methodology to produce digital elevation models (DEMs) in coastal wetlands from satellite remote sensing inputs.
