During the Scripps Scholars Program, I began to understand coastal erosion as more than something I had studied in a classroom. Through fieldwork, I helped collect and analyze coastal data using ArcGIS and contributed data points documenting erosion and environmental change. Seeing individual observations transformed into a map showed me how technology can make environmental changes that happen gradually much easier to recognize and understand.
That experience is why I believe expanding 3D coastal mapping is so important. Traditional photographs and two-dimensional maps can document where a shoreline is located, but they cannot always capture the full extent of how a coastline is changing. 3D mapping can measure changes in elevation, beach volume, dunes, cliffs, and other coastal features. By repeating these surveys over time, researchers can identify where land is disappearing, where sediment is accumulating, and which areas are becoming increasingly vulnerable to erosion and flooding.
This information becomes even more valuable as coastal communities face rising seas, stronger storms, continued development, and habitat loss. Instead of waiting until erosion damages a beach, ecosystem, road, or building, communities can use detailed coastal data to recognize vulnerable areas earlier. Scientists and policymakers can then make more informed decisions about restoration, infrastructure, development, and conservation.
My experience with Scripps changed the way I viewed environmental data. Collecting a single data point can feel insignificant, but when thousands of observations are combined, they reveal patterns that would otherwise be difficult to see. Expanding 3D coastal mapping builds on that same idea. By creating a detailed record of our changing coastlines, we can move from simply observing environmental change to anticipating it—and use science to protect coastal communities before the damage becomes irreversible.
