Special Issue Information

Dear Colleagues,

Proximal and remote sensing as well as their data fusion allow many measurements to be made for environmental (e.g., soil and vegetation) monitoring at depth and in time; however, the derived data from these technologies may include weak, wide, and overlapping absorption bands. The hidden information therefore needs to be extracted to establish a proxy approach to detect vegetation and soil parameters. Chemometrics, the science of extracting information from different databases, including signal and image data by data-driven means, has the potential to address this issue using methods frequently employed in core data-analytic disciplines such as multivariate statistics, applied mathematics, and computer science. Some machine learning algorithms have frequently tried to link proximal/remote sensing data in vegetation and soil variables. However, with the development of large spectral libraries, we need to seize more possibilities to utilize big data analytics to process the spectral data. More advanced machine learning methods as well as deep learning algorithms with higher capability of large-scale processing data might be a solution that supports more sophisticated modeling and permits the easy use of large amounts of computational resources for training such models. The proximal/remote sensing data coupled with chemometrics (e.g., advanced machine learning and especially deep learning methods) therefore offer tremendous but not fully exploited opportunities to monitor and map vegetation and soil variables across various disciplines and on vast spatial scales.

This Special Issue aims i) to report the up-to-date advancements and trends regarding the combination of chemometrics and proximal/remote sensing information by data fusion techniques and ii) to advance the application of chemometrics techniques for proximal/remote sensing-based vegetation and soil monitoring. We welcome contributions in terms of chemometrics methods, including but not limited to novel machine learning and deep learning technique application, potential, and challenges in proximal/remote sensing of vegetation and soil.

Estimation of Organic Carbon in Anthropogenic Soil by VIS-NIR Spectroscopy: Effect of Variable Selection
Remote Sens. 2020, 12(20), 3394; https://doi.org/10.3390/rs12203394 - 16 Oct 2020

Visible and near-infrared reflectance (VIS-NIR) spectroscopy is widely applied to estimate soil organic carbon (SOC). Intense and diverse human activities increase the heterogeneity in the relationships between SOC and VIS-NIR spectra in anthropogenic soil. This fact results in poor performance of SOC estimation models. To improve model accuracy and parsimony, we investigated the performance of two variable selection algorithms, namely competitive adaptive reweighted sampling (CARS) and random frog (RF), coupled with five spectral pretreatments. A total of 108 samples were collected from Jianghan Plain, China, with the SOC content and VIS-NIR spectra measured in the laboratory. Results showed that both CARS and RF coupled with partial least squares regression (PLSR) outperformed PLSR alone in terms of higher model accuracy and less spectral variables. It revealed that spectral variable selection could identify important spectral variables that account for the relationships between SOC and VIS-NIR spectra, thereby improving the accuracy and parsimony of PLSR models in anthropogenic soil. Our findings are of significant practical value to the SOC estimation in anthropogenic soil by VIS-NIR spectroscopy. Full article
