AUTOMATED GIS-BASED TECHNIQUE FOR EVALUATION OF INDIRECT GROWING SEASON ESTIMATIONS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
This article is based on NDWI (Normalized Difference Water Index) which is automatically computed from the daily MODIS data. The main purpose of the article is to tell how the evaluation of NDWI-based growing season estimations can be automated. The NDWI

Qualifying the LIDAR-Derived Intensity Image as an Infrared Band in NDWI-Based Shoreline Extraction

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2018
Obtaining the shoreline of a water body and spatial changes on it provide valuable information regarding the fact that freshwater resources constitute a small fraction of available water resources in the world. Nowadays, various types of image are used to extract shoreline details with the contribution of near infrared response (NIR) band.

‘Using anuran community diversity and Pseudacris crucifer to predict landscape quality across a land use gradient'

Wildlife Biology, EarlyView.
As human‐modified landscape and climate changes proliferate, maintaining biodiversity and understanding the function and quality of available habitat is imperative. As anurans (frogs/toads) such as Pseudacris crucifer, can be an indicator species of habitat quality and ecosystem productivity, studying the anuran community in a mixed‐land use region ...

Modelling of growing season methane fluxes in a high-Arctic wet tundra ecosystem 1997–2010 using in situ and high-resolution satellite data [PDF]

Tellus: Series B, Chemical and Physical Meteorology, 2013
Methane (CH4) fluxes 1997–2010 were studied by combining remotely sensed normalised difference water index (NDWI) with in situ CH4 fluxes from Rylekærene, a high-Arctic wet tundra ecosystem in the Zackenberg valley, north-eastern Greenland.

Seasonal differences in the dominant factors of surface urban heat islands along the urban-rural gradient

Frontiers in Environmental Science, 2022
Urbanization has been accelerating; hence the effect of urban heat island (UHI) has increased. There has been extensive research on spatiotemporal UHI changes and drivers, however, data on the dominant seasonal factors of UHIs and the differences along ...

Assessing habitat suitability for black grouse broods at the bioregional scale

Wildlife Biology, EarlyView.
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.

From research to conservation: Site selection for habitat restoration of a narrowly distributed and critically endangered butterfly

Conservation Science and Practice, EarlyView.
This study focuses on the conservation of a rare butterfly in northwestern Italy threatened by woody encroachment. Using field data, topography, and remote sensing, we modelled habitat suitability and connectivity. A 0.6‐ha site was selected for restoration, illustrating how predictive models can guide targeted conservation actions.

Elevation shapes alpine snow algal blooms and their influence on albedo reduction

New Phytologist, EarlyView.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

Spatial and temporal scales in plant phenotyping for crop water stress assessment: A review

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Water stress is a major limiting factor for crop productivity worldwide, and its impacts are intensifying due to climate variability and increasing water scarcity. This review focuses on the spatial and temporal scales in plant phenotyping as a critical approach to improving crop water‐stress assessment and supporting precision water ...

Impact of Urban Environmental Indices on Surface Temperature in Dhaka: A Policy‐Oriented Perspective

Climate Resilience and Sustainability, Volume 5, Issue 1, June 2026.
ABSTRACT Dhaka's rapid urban expansion has intensified surface heating and degraded environmental quality. This study analyzes environmental indices from 2015 to 2025, revealing a strong positive relationship between built‐up growth and land surface temperature, and negative associations with vegetation and water presence.
