Although coastal change is a natural process, rising sea levels, increased storm surges and man-made developments, are affecting the rate at which this occurs. Beach erosion can impact coastlines by causing damage to real estate, infrastructure and ecosystems.

Photogrammetry is the science of obtaining spatial data from images.  This cost-effective approach delivers high resolution spatial information which can be used for coastal monitoring.  


Digital Elevation Models

Advances in photogrammetry systems for topographic mapping has revolutionized the monitoring and study of conditions in coastal areas. The ability to capture high resolution digital elevation models with high spatial temporal resolutions brings a new generation of coastal monitoring techniques.

Change Detection

If monitoring is successfully implemented, rehabilitation and prevention measures can be put in place to counteract the impact of coastal change. Photogrammetry provides high resolution spatial information that can enable determination of gross changes and the estimation of rates of change.
