“…The variation of altimetric values can be correlated with several soil characteristics, such as texture, water retention capacity and nutrient content [98]. Thus, using GNSS RTK (Real Time Kinematic) technologies has become an alternative for obtaining altimetry data for agriculture, combining high accuracy and good operational performance [99]. Alba et al (2010), cited by [99], compared the data obtained by GPS RTK, in static mode, obtaining correlations of 99%, with topographic surveys carried out conventionally.…”

“…Additionally, according to Hauglin et al [100], the accuracy and precision of the altimetry data obtained through the GNSS RTK technologies are visible, even on board vehicles that travel through the plots. However, according to Rabelo et al [99], when using all-terrain vehicles, the collection of altimetric data should only be carried out in parallel lines to the crop lines, with a speed of ±2.2 m/s. The use of these new technologies, combined with the use of specific computer programs, facilitating field and office work, also significantly improves the accuracy of measurements since they are less subject to interference from errors caused by environmental conditions and also from errors caused by human interference [95].…”

Montado Mediterranean Ecosystem (Soil–Pasture–Tree and Animals): A Review of Monitoring Technologies and Grazing Systems

Montado is an agro-silvo-pastoral ecosystem characteristic of the south of Portugal and called Dehesa in Spain. Its four fundamental components—soil, pasture, trees, and animals—as well as the climate make Montado a highly complex ecosystem. This review article provides an overview of the state of the art of Montado from the point of view of the agro-silvo-pastoral ecosystem and the scientific work carried out in this context. Thus, the aim is: (i) to describe and characterize the Montado ecosystem, as an agro-silvo-pastoral system; (ii) to reveal experimental tests carried out, technologies used or with the potential to be used in the monitoring of Montado; (iii) to address other technologies, carried out in similar and different agro-silvo-pastoral ecosystems from south Portugal. This review consists of three chapters: (a) components of Montado and their interactions; (b) advanced technologies for monitoring Montado; (c) grazing systems. No review article is known to provide an overview of Montado. Thus, it is essential to carry out research on grazing and its effects on the soil and pasture in the Montado ecosystem.

“…The quality was verified by comparing the ground targets' coordinates extracted from the point clouds to the measured ones on the field with indirect geo-referencing utilizing GNSS. In [13], the quality of altimetry surveys with GNSS RTK receiver aboard an all-terrain vehicle is evaluated. In [6], a spatial data management methodology to focus on enabling free access and viewing interesting data in real time for supporting emergency managers is proposed.…”

Global navigation satellite systems (GNSS) have played an important role in commercial, military and industrial navigation as well as cloud computing, geospatial analysis and digital modeling. Nowadays, with the advancement of science and technology, the capabilities of electronic warfare, including signal jamming, interference, and spoofing, have also advanced. Attacks and threats at simple, intermediate and advanced levels, endanger the security and reliability of GNSS in the commercial, industrial and military fields such as geolocation, geospatial techniques and digital twins. Therefore, coping with this problem and challenge is very important in maintaining security and reliability. At present, various methods and algorithms have been designed and utilized based on statistical properties, moving receiver, artificial array, wavelet transform and etc., each of which has advantages, disadvantages and blind spots. In this paper, the necessity and requirements for dealing with GNSS threats are emphasized, and the most important researches in the field of GNSS threat (jamming/interference/spoofing) detection and mitigation are studied and reviewed. Their advantages and disadvantages are discussed, and improving areas are also proposed.
