The Global Retrieval of ATSR Cloud Parameters and Evaluation (GRAPE) project has produced a global dataset of cloud and aerosol properties from the Along Track Scanning Radiometer-2 (ATSR-2) instrument, covering the time period 1995–2001. This paper presents the validation of aerosol optical depths (AODs) over the ocean from this product against AERONET sun-photometer measurements, as well as a...

Remote sensing image automatic registration technology is one of the image processing technologies that have been developed rapidly in recent years, and automatic matching of control points is the core work of the automatic registration. Considering the influence of the cloud points and the phenomenon of uneven distribution of control points in AVHRR images, An automatic matching method of cont...

Spatial and temporal vegetation contrasts between the nations of Haiti and the Dominican are analyzed using NDVI data derived from 30m resolution Landsat imagery and 8km resolution AVHRR imagery from the NOAA / NASA Pathfinder database. Analysis of vegetation dynamics in the Hispaniola border region indicates denser vegetation cover and a stronger correlation between elevation, slope, and NDVI ...

AVHRR is an imager flying on polar meteorological satellites that, due to its spatial resolution (about 1 km at Nadir view), produces a huge amount of data. A method based on the wavelet packet transform is devised to compress AVHRR images. The method is driven by the compression error (application dependent), so that different types of images have the same quality. The best basis wavelet packe...

The long distance movement of marine turtles is one of the wonders of the natural world, with recapture techniques showing how some species move thousands of kilometers across the ocean (Meylan, 1995). The Mid-Atlantic serves as a host environment for a number of sea turtle species that encompasses their seasonal migration routes. Currently, out of the six turtle species all are labeled as eith...
