Special Issue Information

Dear Colleagues,

Advances in satellite technology have made it possible to use optical images to monitor the environment in multiple dimensions. Among other tasks, these images can be used to track changes in land use, monitor vegetation growth, and health, spot changes in water quality, estimate the size of natural disasters, and map the current status of the environment and ecosystem. In addition, multi-dimensional remote sensing can also provide information on the physical and chemical properties of the environment, which can be used to improve resource management and environmental conservation efforts. Thus, remote sensing is increasingly becoming a powerful tool for monitoring and understanding the Earth's environment. The resolution and coverage of these images have also improved, allowing for more accurate and detailed data collection. Additionally, machine learning and deep learning techniques are commonly used to analyze images and extract geospatial information.

With the growing volume of optical images from various open-source and commercial satellite and sensor platforms and developed algorithms with computing efficiency, extracting geospatial information from remotely sensed data evolved into a big data management problem and the dimensionality of the data makes implementation of the approaches challenging.

This Special Issue aims to collect original research regarding the advancements in applications, algorithms, and approaches in monitoring and mapping the environment, with a wide aspect of dimensionality including multi-temporal, multi-sensor, and multi-source data fusion. Articles may address but are not limited to the following research topics:

  • Multisensory–multitemporal data fusion for environmental monitoring applications.
  • Integration of in-situ data with optical satellite images for multi-dimensional environmental monitoring applications.
  • Machine learning and deep learning-based algorithms for multi-dimensional monitoring applications.
  • 3D modelling for change detection, natural disaster management, and urbanization.
  • Advances in digital surface/bathymetry model generation from satellite, airborne, or UAV-based systems.

For more than 50 years, marine and remote sensing researchers have investigated the methods of bathymetry extraction by means of active (altimetry) and passive (optics) satellite sensors. These methods, in general, are referred to as satellite-derived bathymetry (SDB). With the advances in sensor capabilities and computational power and recognition by the International Hydrographic Organization (IHO), SDB has been more popular than ever in the last 10 years. Despite a significant increase in the number of studies on the topic, the performance of the method is still variable, mainly due to environmental factors, the quality of the deliverables by sensors, the use of different algorithms, and the changeability in parameterization. In this study, we investigated the capability of Gokturk-1 satellite in SDB for the very first time at Horseshoe Island, Antarctica, using the random forest- and extreme gradient boosting machine learning-based regressors. All the images are atmospherically corrected by ATCOR, and only the top-performing algorithms are utilized. The bathymetry predictions made by employing Gokturk-1 imagery showed admissible results in accordance with the IHO standards. Furthermore, pixel brightness values calculated from Sentinel-2 MSI and tasseled cap transformation are introduced to the algorithms while being applied to Sentinel-2, Landsat-8, and Gokturk-1 multispectral images at the second stage. The results indicated that the bathymetric inversion performance of the Gokturk-1 satellite is in line with the Landsat-8 and Sentienl-2 satellites with a better spatial resolution. More importantly, the addition of a brightness value parameter significantly improves root mean square error, mean average error, coefficient of determination metrics, and, consequently, the performance of the bathymetry extraction.
