Geoscience and Remote Sensing Letters (GRSL)

The IEEE GEOSCIENCE AND REMOTE SENSING LETTERS is a monthly publication for short papers (maximum length 5 pages) addressing new ideas and formative concepts in remote sensing as well as important new and timely results and concepts.
Papers should relate to the theory, concepts, and techniques of science and engineering as applied to sensing the earth, oceans, atmosphere, and space, and the processing, interpretation, and dissemination of this information.
The technical content of papers must be both new and significant. Experimental data must be complete and include sufficient description of experimental apparatus, methods, and relevant experimental conditions. GRSL encourages the incorporation of “extended objects” or “multimedia” such as animations to enhance the shorter papers. As soon as papers are accepted and materials are available at IEEE, they will appear online through the IEEE digital library Xplore.

Optimizing Hopfield Neural Network for Spectral Mixture Unmixing on GPU Platform

The Hopfield neural network (HNN) has been demonstrated to be an effective tool for the spectral mixture unmixing of hyperspectral images. However, it is extremely time consuming for such per-pixel algorithm to be utilized in real-world applications. I…

Bayesian Classification of Hyperspectral Imagery Based on Probabilistic Sparse Representation and Markov Random Field

This letter presents a Bayesian method for hyperspectral image classification based on the sparse representation (SR) of spectral information and the Markov random field modeling of spatial information. We introduce a probabilistic SR approach to estim…

Utilizing Multiple Subpixel Shifted Images in Subpixel Mapping With Image Interpolation

In this letter, multiple subpixel shifted images (MSIs) were utilized to increase the accuracy of subpixel mapping (SPM), based on the fast bilinear and bicubic interpolation. First, each coarse spatial resolution image of MSI is soft classified to obt…

Retrieving Leaf Area Index From Landsat Using MODIS LAI Products and Field Measurements

Land surface models that operate at multiple spatial resolutions require consistent leaf area index (LAI) inputs at each scale. In order to produce LAI from Landsat imagery that is consistent with the Moderate Resolution Imaging Spectroradiometer (MODI…

Investigation of the Capability of $Hhbox{-}alpha$ Decomposition of Compact Polarimetric SAR

Recently, there has been an increasing interest in compact polarimetry (CP), which helps to reduce the complexity, cost, mass, and data rate of synthetic aperture radar (SAR) systems while attempting to maintain many capabilities of a fully polarimetri…

An Improved Land-Surface Albedo Algorithm With DEM in Rugged Terrain

The influence of topography on land-surface bidirectional reflectance and albedo should be considered in rugged terrain. However, land-surface albedo algorithms neglect topographic effects, leading to errors in estimating the albedo in rugged terrain. …

A Knowledge-Based Target Relocation Method for Wide-Area GMTI Mode

This letter deals with the issue of moving-target relocation in wide-area ground moving-target indication for dual-channel radar systems. Due to channel mismatch, along-track baseline error, the existence of across-track baseline, etc., it is difficult…
