In this study the variations in surface reflectance properties and pigment concentrations of Antarctic moss over species, sites, microtopography and with water content were investigated. It was found that species had significantly different surface reflectance properties, particularly in the region of the red edge (approximately 700 nm), but this did not correlate strongly with pigment concentr...

Headland and field edges have a higher traffic frequency compared to the centre, which causes more compaction. Most repeated compaction is located at entrance area headland during machinery turning material transporting that takes place fertilisation, herbicide laying, harvesting of fields, could cause soil structure destruction yield reduction. In this study, differences between headland, edge...

There is a need to develop indicators of mangrove condition using remotely sensed data. However, remote estimation of leaf and canopy biochemical properties and vegetation condition remains challenging. In this paper, we (i) tested the performance of selected hyperspectral and broad band indices to predict chlorophyll concentration (CC) on mangrove leaves and (ii) showed the potential of Landsa...

Abstract. One of the most important issues in urban management is existence clay-made houses or around cities. By hypothesis that these phenomena are spectrally and spatially behaviour differently from other land uses covers. This study attempts to detect identify through different image processing methods. In this regard, Sentinel 1, 2, Landsat 8 OLI thermal images Yazd city have been analysed...

Plastic greenhouses (PGs) are widely built near cities in China to produce vegetables and fruits. In order promote sustainable agriculture, rural landscape construction, better manage water resources, numerous remote sensing methods have been developed identify monitor the distribution of PGs, which many map PGs based on spectral responses geometric shapes. this study, we proposed a new fine- c...

Understanding the spatial variability of soil texture classes is essential for agricultural management and environment sustainability. Sentinel-2 data offer valuable vegetation information as proxies properties inference. However, applications them in classification are still limited. This study investigated usefulness predicting class using an interpretable machine learning (ML) strategy. Spec...

• The absolute mean error of the SuperDove surface reflectance were 6%. was on average almost identical to Sentinel-2. probability 90% acquiring stable multi-satellite reflectance. 68% single-satellite data more likely acquire time series strongly correlated Sentinel-2 vegetation. Advances in capabilities commercial CubeSat constellations have enabled retrieval multi-spectral over Earth’s terre...

Optimizing crop yield is one of the main focuses precision farming. Variability in within a field can be influenced by many factors and it necessary to better understand their interrelationships before management methods successfully used optimize quality. In this study, NDVI time-series from Sentinel-2 imagery effects landscape position, topographic features, weather conditions on agronomic sp...
