Image segmentation and geographic object-based image analysis (GEOBIA) were proposed around the turn of the century as a means to analyze high-spatial-resolution remote sensing images. Since then, object-based approaches have been used to analyze a wide range of images for numerous applications. In this Editorial, we present some highlights of...

Land use/land cover (LULC) maps are now being used across disciplines for many different types of applications, e.g., to analyze urban heat islands or rainfall-runoff dynamics. Traditional map accuracy metrics are limited in this regard, as they only assess LULC map thematic accuracy. In reality, some types of misclassification lead to larger...

A few studies have evaluated the impact of land use land cover (LULC) change on surface water quality in the Vietnamese Mekong Delta (VMD), one of the most productive agricultural deltas in the world. This study aims to evaluate water quality parameters inside full- and semi-dike systems and outside of the dike system during the wet and dry season...

A few decades ago, the surface waterbodies in Hanoi, Vietnam, were an important source of water for various usages. However, because of the rapid global changes, the current status of most of the river system is very critical from the environmental, aesthetic and commercial usage points of view. Henceforth, this research work focused on assessing...

Owing to the huge number of species observations that can be collected by non-professional scientists, “citizen science” has great potential to contribute to scientific knowledge on invasive alien species (IAS). Citizen science has existed for centuries, but the recent adoption of information and communications technology (ICT) in this field (e.g...

National policies to achieve the SDGs may lead to inequitable development at the sub-national levels. The research project "River basins as 'living laboratories' for achieving the SDGs across national and sub-national scales", collaborated among University of Glasgow (UK), Loughborough University (UK), Nankai University (China) and the Institute...

Tonle Sap Lake (TSL), the largest lake in South East Asia, is under increasing pressure from pollution, land-use change, climate change, and development activities in the lake, its basin and the Mekong Basin. Recent changes in the lake hydrological system and its floodplains are becoming a great concern for hundreds of communities relying on the...

Green fractional vegetation cover (fc) is an important phenotypic factor in the fields of agriculture, forestry, and ecology. Spatially explicit monitoring of fc via relative vegetation abundance (RA) algorithms, especially those based on scaled maximum/minimum vegetation index (VI) values, has been widely investigated in remote sensing research...

Just a few decades ago, Adyar River in India’s city of Chennai was an important source of water for various uses. Due to local and global changes (e.g., population growth and climate change), its ecosystem and overall water quality, including its aesthetic value, has deteriorated, and the water has become unsuitable for commercial uses. Adverse...
