Salt Marsh Monitoring in Jamaica Bay, New York from 2003 to 2013: A Decade of Change from Restoration to Hurricane Sandy

Abstract: This study used Quickbird-2 and Worldview-2, high resolution satellite imagery, in a multi-temporal salt marsh mapping and change analysis of Jamaica Bay, New York. An object-based image analysis methodology was employed. The study seeks to understand both natural and anthropogenic changes caused by Hurricane Sandy and salt marsh restoration, respectively. The objectives of this study were to: (1)

“…To improve management outcomes, understanding vegetation trends at larger scales is critical, and remote sensing of aerial imagery provides a cost-effective means of monitoring tidal wetland sites where access may be challenging. In particular, object-based image analysis (OBIA) is a promising technique for monitoring tidal salt marshes (Dronova, 2015), and has been applied to looking at vegetation across spatial scales in these ecosystems Gorelick, 2013, 2016), but has only recently been used to explore change over time (Campbell et al, 2017). Previous geospatial work using aerial imagery has largely taken place in the North SF Bay, where freshwater river runoff buffers Bay salinity .…”

“…Often, pixel-based approaches are hampered by their inability to consider both the pixel identity and spatial context in classifying landscapes . To account for these issues, object-based approaches are increasingly used to categorize heterogeneous landscapes like tidal wetlands (Wang et al, 2004;Gorelick, 2013, 2016;Dronova, 2015;Campbell et al, 2017). In tidal wetland restoration projects, sediment is highly dynamic over time, imagery must be gathered at low tide for optimal visualization while surface water and debris can vary greatly between images Fulfrost et al, 2012).…”

“…Hyperspectral remote sensing provides promising approaches in the monitoring of global tidal wetlands [47][48][49]. High spatial resolution satellite data have been effectively applied in water and wetland mapping and change analysis [50][51][52][53][54]. Sentinel satellites have demonstrated enhanced capacities in the monitoring of changing water and wetland environments, in recent years [55][56][57][58][59][60].…”

“…For wetland process studies, polar orbiting optical and synthetic aperture radar (SAR) satellites with spatial resolutions of 5-250 meters have generally represented a compromise in terms of spatial resolution and temporal resolution (revisit time), which are both important for monitoring wetland dynamics. Satellite imagery with spatial resolutions finer than five meters is more suited to characterizing wetland spatial variability and producing detailed wetland maps [19][20][21]. However, many of the satellites acquiring this high spatial resolution imagery are commercial, requiring users to purchase imagery and at times also requiring tasking of the satellites for image acquisition over a given study site.…”
