Effects of atmospheric correction and pansharpening on LULC classification accuracy using WorldView-2 imagery

Information Processing in Agriculture, 2015
Changes of Land Use and Land Cover (LULC) affect atmospheric, climatic, and biological spheres of the earth. Accurate LULC map offers detail information for resources management and intergovernmental cooperation to debate global warming and biodiversity ...

Scaling up soybean breeding: Satellite imagery delivers accurate maturity estimation across plot sizes

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Accurate and scalable phenotyping is essential for accelerating genetic gain in soybean (Glycine max (L.) Merr.) breeding programs. Traditional methods for estimating physiological maturity are labor‐intensive and prone to subjectivity, limiting throughput and consistency. This study evaluates the potential of high‐resolution satellite imagery

Pixels and Patterns in the Sand: Decoding Coastal Dune Habitats With Multi‐Resolution CNNs

Journal of Vegetation Science, Volume 37, Issue 5, September/October 2026.
Coastal dune habitats are small, fragmented, and challenging to map. We tested convolutional neural networks (CNNs) on an Italian coastal dune system, comparing four remote sensing datasets: UAV, airborne, Google Earth, and WorldView‐3 satellite. Mapping accuracy dropped sharply with coarser spatial resolution, while adding spectral bands mostly ...

Improving Remote Sensing Image Super-Resolution Mapping Based on the Spatial Attraction Model by Utilizing the Pansharpening Technique

Remote Sensing, 2019
The spatial distribution information of remote sensing images can be derived by the super-resolution mapping (SRM) technique. Super-resolution mapping, based on the spatial attraction model (SRMSAM), has been an important SRM method, due to its ...

Counting elephants from space: An analytic framework for wildlife abundance surveys in heterogeneous terrain using satellites and AI

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
We determine the analytic framework for satellite surveying using AI, for species such as elephants in heterogeneous terrain such as savannahs. For the elephant hotspot of Botswana, we compare satellite surveying to traditional aerial surveying methods.

Pansharpening Based on Adaptive High-Frequency Fusion and Injection Coefficients Optimization

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
The purpose of pansharpening is to fuse a multispectral (MS) image with a panchromatic (PAN) image to generate a high spatial-resolution multispectral (HRMS) image.

Assessing habitat suitability for black grouse broods at the bioregional scale

Wildlife Biology, Volume 2026, Issue 4, July 2026.
The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

No-Reference Quality Assessment for Pansharpened Images via Opinion-Unaware Learning

IEEE Access, 2019
The high-quality pansharpened image with both high spatial resolution and high spectral fidelity is highly desirable in various applications. However, existing pansharpening methods may lead to spatial distortion and spectral distortion.
