Analysis of Optimal Thresholds for the Identification of Open Water Using MODIS-Derived Spectral Indices in Two Coastal Wetland Systems, Mexico

This research paper evaluates the use of MODIS satellite data and spectral indices to map open water surfaces in coastal wetland systems, specifically testing the effectiveness of the MNDWI6 index and a new threshold optimization method.

• The study determined that the MNDWI6 spectral index method is an effective tool for mapping large water bodies and observing their variations.
• The implementation of a new method for optimizing detection thresholds leads to a significant increase in the accuracy of open water detection.
• MODIS satellite data can be utilized for large-scale eco-hydrological studies of wetlands, monitoring floods and droughts, and assessing the effects of climate change, land-use, and dam development.
