A deep-learning model for the amplitude inversion of internal waves based on optical remote-sensing images
The amplitude of internal waves is an important parameter for the remote-sensing detection. However, there is no analytic method developed for the amplitude inversion of internal waves based on optical remote-sensing images. In this article, the deep-...
Remote-sensing imagery classification using multiple classification algorithm-based AdaBoost
AdaBoost demonstrates excellent performance in remote sensing RS image classification, but as it works on only one classification algorithm, the disadvantage of the classification algorithm itself is difficult to overcome, resulting in limitations in ...
Planar block adjustment and orthorectification of Chinese spaceborne SAR YG-5 imagery based on RPC
Yaogan-5YG-5, launched in December 2008, is a Chinese high-resolution spaceborne synthetic aperture radar SAR satellite, with a ground resolution of 3 m. However, the direct geometric positioning accuracy of YG-5 slant range images is low and so is the ...
Multidate MESMA for monitoring vegetation growth forms in southern California shrublands
Identifying habitats that should be protected from further disturbance or conversion and isolating high-risk areas is a focus of community habitat plans in southern California shrublands. Larger wildfires are occurring at shorter intervals in recent ...
A regression modelling approach for optimizing segmentation scale parameters to extract buildings of different sizes
Multiresolution segmentation MRS is one of the most commonly used image segmentation algorithms in the remote-sensing community. This algorithm has three user-defined parameters: scale, shape, and compactness. The scale parameter SP is the most crucial ...
Chinese satellite photogrammetry without ground control points based on a public DEM using an efficient and robust DEM matching method
Photogrammetry based on high-resolution satellite image can acquire geospatial information within a large area rapidly and timely, but its geopositioning accuracy is highly dependent on ground control points. Under the background of global mapping, a ...
Lightning, rainfall, AOD, and convection variabilities in the monsoon zone of India
Lightning, rainfall, aerosol optical depth AOD, and convection variabilities in the monsoon zone of India are studied during the period 2001–2012. Accumulated rain is used to study rainfall and the parameters surface temperature, convective available ...
A low-cost near-infrared digital camera for fire detection and monitoring
The human visualization system is not optimally suited for fire detection. Smoke occlusion heavily limits flame visibility and low flames can be difficult to see. Thermal infrared TIR sensors mitigate these effects but come at high costs >$3000 that ...
Fast detection of significantly transformed areas due to illegal waste burial with a procedure applicable to Landsat images
The purpose of this work is the development of a processing procedure with Landsat images applicable to agro-ecosystems that can produce results in heavily transformed areas where suspicion of illegal waste burial is high.
A modified mean filter for improving the classification performance of very high-resolution remote-sensing imagery
Very high resolution VHR remote-sensing imagery can reveal ground objects in great detail, depicting the colour, shape, size and structure of the objects. However, VHR also leads to a large amount of noise in the spectra, which may reduce the ...
Comprehensive drought index as an indicator for use in drought monitoring integrating multi-source remote sensing data: a case study covering the Sichuan-Chongqing region
Numerous meteorological drought-monitoring indices and remote-sensing-based spatial drought monitoring indices have been developed and applied to monitor drought in different ways. However, individual indices have obvious deficiencies in terms of their ...
Land-use land-cover classification analysis of Giba catchment using hyper temporal MODIS NDVI satellite images
Landsat-based land-use land-cover LULC mapping studies were previously conducted in Giba catchment, comprising an area of 4019 km2. No attempt has been done to map LULC of this catchment through the analysis of Moderate Resolution Imaging ...
The effect of fusing Sentinel-2 bands on land-cover classification
The Sentinel-2 satellite currently provides freely available multispectral bands at relatively high spatial resolution but does not acquire the panchromatic band. To improve the resolution of 20 m bands to 10 m, existing pansharpening methods Brovey ...
Enhanced automatic detection of human settlements using Sentinel-1 interferometric coherence
This article presents an experiment in which multi-temporal interferometric coherence calculated from 6-days Sentinel-1A and Sentinel-1B image pairs and backscatter intensity σ° are jointly used for the extraction of built-up areas in the framework of ...
Landsat approaches to map agro-pastoral farming in the wetlands of southern Sudan
Machine-learning algorithms MLA are coming of age within satellite remote sensing SRS. This study compares the performance of a number of MLAs with more traditional indices and algorithms to map annual agro-pastoralist farming activity in southern ...

Burnt area is a critical parameter for estimating emissions of greenhouse gases associated with biomass burning. Several burnt area products BAPs derived from Earth Observation satellites/sensors have been released; these are based on different spatial ...
Long-term spatiotemporal variability of southwest Florida whiting events from MODIS observations
Whiting events, or waters with high concentrations of fine-grained calcium carbonate, have been previously reported in southwest Florida using three years of observations from the Moderate Resolution Imaging Spectroradiometer. Here, the initial case ...
Estimation of air temperature and reference evapotranspiration using MODIS land surface temperature over Greece
Moderate Resolution Imaging Spectroradiometer MODIS, land surface temperature data, during daytime LSTday or night-time LSTnight, were employed for predicting maximum Tmax or minimum Tmin air temperature measured at ground stations, respectively, in ...
