Abstract Adopting a low spatial resolution remote sensing imagery to get an accurate estimation of Land Use Cover is difficult task perform. Image fusion plays big role map the Cover. Therefore, This study aims find out refining method for estimating using these steps; (1) applying three pan-sharpening approaches combine panchromatic that has high with multispectral resolution, (2) employing fi...

Multispectral (MS) remote sensing (RS) images are of great interest for various applications, yet, quite often, a MS product exhibits one or more noisy bands, strip lines even missing bands which leads to decreased confidence in the information it contains. Meeting this challenge, current paper proposes UNet based neural network architecture reconstruct spectral band. The worst-case scenario is...

Abstract: Several frequency-based spectral similarity measures, derived from commonly-used ones, are developed for hyperspectral image classification based on the frequency domain. Since the frequency spectrum (magnitude spectrum) of the original signature for each pixel from hyperspectral data can clearly reflect the spectral features of different types of land covers, we replace the original ...

Stone is one of the most common materials used as a building material in central Europe for centuries. Historical objects are endangered by degradation procedures coming from physical, chemical and biological weathering agents.The process itself should be analysed detail order to prevent historical application proper restoration cleaning techniques. Within our research, sandstone block was duri...

There is a growing need to map rice ecosystems and develop methods for monitoring distribution in order account rapid land use changes worldwide. In this study, we evaluated methodology based on Vegetation Indices time series derived from an 8-day MODIS composite identify fields maps that can be timely updated the long term. We have assessed potential of Spectral Shape Index compared its perfor...

In the European Citclops project, with a prime aim of developing new tools to involve citizens in the water quality monitoring of natural waters, colour was identified as a simple property that can be measured via a smartphone app and by dedicated low-cost instruments. In a recent paper, we demonstrated that colour, as expressed mainly by the hue angle (α), can also be derived accurately and co...

This paper reports on a test of the ability to estimate above-ground biomass of tropical secondary forest from canopy spectral re ectance using satellite optical data. Landsat Thematic Mapper data were acquired concurrent with Ž eld surveys conducted in secondary forest fallows nearManaus, Brazil and Santa Cruz de la Sierra, Bolivia. Measurements of age and above-ground live biomass were made ...

It is necessary to monitor and identify mangroves types and spatial extent near coastal areas because it plays an important role in coastal ecosystem and environmental protection. This research aims at identifying and mapping mangroves types along Karachi coast ranging from 24.79 to 24.85 in latitude and 66.91 to 66.97 in longitude using hyperspectral remote sensing data and techniques. Image a...

This study used a reef-up approach to map coral reef benthos, substrates and bathymetry, with high spatial resolution hyperspectral image data. It investigated a physics-based inversion method for mapping coral reef benthos and substrates using readily available software: Hydrolight and ENVI. Compact Airborne Spectrographic Imager (CASI) data were acquired over Heron Reef in July 2002. The spec...
