BACKGROUND We report the outcome of sentinel node biopsy (SNB) for staging the neck in a consecutive cohort of 34 patients with T1/2 clinically N0 oral carcinoma. METHODS SNB was performed along with resection of primary tumor. Neck dissection was reserved for failure of SNB or pathologically positive sentinel nodes (pN+). RESULTS Sentinel node identification was successful in 32 of 34 pati...

Abstract. In this work, we investigate the potential of DESIS hyperspectral data for water colour applications as preparation exploitation from future EnMAP mission. We show results on intercomparison Level 2 sensor, Sentinel-2 MultiSpectral Instrument (S2-MSI) and Sentinel-3 Ocean Land Colour (S3-OLCI) processed with Polymer atmospheric correction. Examples mapping quality parameters in inland...

Remote sensing offers a way to map crop types across large spatio-temporal scales at low costs. However, mapping is challenging in heterogeneous, smallholder farming systems, such as those India, where field sizes are often smaller than the resolution of historically available imagery. In this study, we examined potential relatively new, high-resolution imagery (Sentinel-1, Sentinel-2, and Plan...

The use of remote sensing images to detect forest changes is great significance for resource management. With the development and implementation deep learning algorithms in change detection, a large number models have been designed multi-phase images. Although synthetic aperture radar (SAR) data strong potential application detection tasks, most existing learning-based optical imagery. Therefor...

Informative spectral bands for green leaf area index (LAI) estimation in two crops were identified and generic models for soybean and maize were developed and validated using spectral data taken at close range. The objective of this paper was to test developed models using Aqua and Terra MODIS, Landsat TM and ETM+, ENVISAT MERIS surface reflectance products, and simulated data of the recently-l...

Over the years, remote sensing technology has become an important means to obtain accurate agricultural production information, such as crop type distribution, due its advantages of large coverage and a short observation period. Nowadays, cooperative use multi-source imagery new development trend in field classification. In this paper, polarimetric components Sentinel-1 (S-1) decomposed by mode...

Land cover and land use maps derived from satellite remote sensing imagery are critical to support biodiversity and conservation, especially over large areas. With its 10 m to 20 m spatial resolution, Sentinel-2 is a promising sensor for the detection of a variety of landscape features of ecological relevance. However, many components of the ecological network are still smaller than the 10 m pi...
