introduction: several radiotracers are being used for sentinel node mapping in patients with breast cancer. in the current study, we reported our experience with 99m-tc phytate for sentinel node mapping in mashhad university of medical sciences. methods: all breast cancer patients who underwent sentinel node mapping using 99m-tc phytate were included. all patients received intradermal peri-areo...

Forest canopy height is defined as the distance between highest point of tree and ground, which considered to be a key factor in calculating above-ground biomass, leaf area index, carbon stock. Large-scale forest monitoring can provide scientific information on deforestation degradation policymakers. The Ice, Cloud, Land Elevation Satellite-2 (ICESat-2) was launched 2018, with Advanced Topograp...

This paper investigates the potential of cloud-free virtual optical imagery generated using synthetic-aperture radar (SAR) images and conditional generative adversarial networks (CGANs) for early crop mapping, which requires at optimal date classification. A two-stage CGAN approach, including representation generation stages, is presented to generate Sentinel-2 spectral bands all available info...

Mapping of the Arctic region is increasingly important in light global warming as land cover maps can provide foundation for upscaling ecosystem properties and processes. To this end, satellite images an invaluable source Earth observations to monitor areas that are otherwise difficult access. With continuous development new satellites, it optimize existing further monitoring ecosystems. This s...

Even though research has shown that the spectral parameters of yellow-edge, red-edge and NIR (near-infrared) shoulder wavelength regions are able to estimate green cover leaf area index (LAI), a large amount dead materials in grasslands challenges accuracy their estimation using hyperspectral remote sensing. However, exact impact vegetation on these remains unclear. Therefore, we evaluated infl...

The continuously increasing demand of accurate quantitative high quality information on land surface properties will be faced by a new generation of environmental Earth observation (EO) missions. One current example, associated with a high potential to contribute to those demands, is the multi-spectral ESA Sentinel-2 (S2) system. The present study focuses on the evaluation of spectral informati...

Abstract Early prediction of crop production by remote sensing (RS) may help to plan the harvest and ensure food security. This study aims improve quantification yield, grain protein concentration (GPC), nitrogen (N) output in winter wheat with RS imagery. Ground-truth traits were measured at flowering a field experiment combining four N two water levels central Spain over 2 years. Hyperspectra...
