Due to the increased melting season in the arctic regions, especially in the seas surrounding Greenland, there has been an increased interest in utilizing these water ways, both as a efficient transport route and an attractive leisure destination. However, with heavier traffic comes an increased risk of accidents. Due to the immense size and poor infrastructure of Greenland, it is not feasible ...

[1] High-resolution (0.1 0.1 ) geostationary satellite infrared radiances at 11 mm in combination with gridded (2.5 2.0 ) hourly surface precipitation observations are employed to document the spatial structure of the diurnal cycle of summertime deep convection and associated precipitation over North America. Comparison of the diurnal cycle pattern between the satellite retrieval and surface ob...

The purpose in the release of such reports is to facilitate the exchange of technical information and to inform the public of technical developments which may form the basis for a final EPA decision, positio...

In this paper, we extract the waterline from synthetic aperture radar (SAR) images to illustrate coastline change in Shanghai, China. Nine ERS-2 and ENVISAT SAR images acquired between 1998 and 2006 were selected and a new land-water classification scheme was implemented to obtain coastline. The results show that the seaward coastline change between 1998 and 2000 is faster in the eastern part a...

In this article, we are dealing with the problem of coastline extraction in Very High Resolution (VHR) multispectral images (Quickbird) on the Normandy Coast (France). Locating precisely the coastline is a crucial task in the context of coastal resource management and planning. In VHR imagery, some details on coastal zone become visible and the coastline definition depends on the geomorphologic...

Coastline change reflects the dynamics of natural processes and human activity, and influences the ecology and environment of the coastal strip. This study researched the change in coastline and sea area of the Bohai Sea, China, over a 30-year period using Landsat TM and OLI remote sensing data. The total change in coastline length, sea area, and the centroid of the sea surface were quantified....

Information on the pattern, rhythm and long-term trend of shoreline dynamics is vital to managing the coast, especially in mapping risk areas and in establishing the width of construction setback lines. Unfortunately, such data are often missing or where present of doubtful quality. In this paper, we share our experience in mapping coastline change in Singapore, using geographic information sys...

Continued sea-level rise and coastal development have led to considerable concerns on coastline changes along inhabited islands. Analysis of long-term coastline changes of islands is however limited due to unavailable data and the cost of field work. In this study, high-resolution images taken from 1970–2011 at an interval of about 10 years and topographic maps were collected to determine coast...

Rising sea levels are of significant concern as global temperatures continue to mount. Predicted increases in sea level place coastal regions and cities in danger. This danger is far from uniform; many factors contribute to the relative infiltration of water and its consequent effect on land. Naive considerations of elevation alone would result in a poor model of what happens in real life. This...

A complete, high-resolution coastline of Antarctica, extracted from an orthorectified mosaic of Radarsat-1 synthetic aperture radar (SAR) images through a sequence of automated image processing algorithms, is presented. A locally adaptive thresholding method is used to segment the orthorectified SAR images, while image-object formation and labeling, and edgetracing techniques are used to proces...
