Special Issue Information

Dear Colleagues,

Technological development, integration, and adoption in both agriculture and forestry management practices continues to grow. The need to increase yield and quality and introduce sustainable practices while simultaneously reducing disease incidence and minimizing chemical inputs requires careful and detailed management. Knowledge with the highest detail level possible about context, culture, and environmental parameters that can influence both agriculture and forests’ high variabilities is needed to improve management practices.

Remote sensing enables the acquisition of diverse data with variable levels of detail, both in agriculture and in forestry. Indeed, the use of satellites, manned aircrafts, and unmanned aerial vehicles, equipped with different types of sensors (e.g., RGB, NIR, LiDAR, multi- and hyperspectral and thermal) has been gaining special attention in their different applications in agriculture and forests.

Moreover, the need for systems that are able to deal with the massive amounts of data being generated by remote sensing is also emerging. They must be capable of aggregating and extracting useful and intelligible information to stakeholders, preferably in a (semi)automatic way, throughout the application of deep learning.

This Special Issue aims at collecting new developments, methodologies, algorithms, best practices, and applications in remote sensing. We welcome submissions that provide the community with the most recent advancements on all aspects of remote sensing.

Sustainable management of orchard fields requires detailed information about the tree types, which is a main component of precision agriculture programs. To this end, hyperspectral imagery can play a major role in orchard tree species mapping. Efficient use of hyperspectral data in combination with field measurements requires the development of optimized band selection strategies to separate tree species. In this study, field spectroscopy (350 to 2500 nm) was performed through scanning 165 spectral leaf samples of dominant orchard tree species (almond, walnut, and grape) in Chaharmahal va Bakhtiyari province, Iran. Two multivariable methods were employed to identify the optimum wavelengths: the first includes three-step approach ANOVA, random forest classifier (RFC) and principal component analysis (PCA), and the second employs partial least squares (PLS). For both methods we determined whether tree species can be spectrally separated using discriminant analysis (DA) and then the optimal wavelengths were identified for this purpose. Results indicate that all species express distinct spectral behaviors at the beginning of the visible range (from 350 to 439 nm), the red edge and the near infrared wavelengths (from 701 to 1405 nm). The ANOVA test was able to reduce primary wavelengths (2151) to 792, which had a significant difference (99% confidence level), then the RFC further reduced the wavelengths to 118. By removing the overlapping wavelengths, the PCA represented five components (99.87% of variance) which extracted optimal wavelengths were: 363, 423, 721, 1064, and 1388 nm. The optimal wavelengths for the species discrimination using the best PLS-DA model (100% accuracy) were at 397, 515, 647, 1386, and 1919 nm. Full article
