Spectral similarity measures such as the Spectral Angle Mapper (SAM) treat all spectral bands equally, an assumption difficult to justify for modern imaging spectroscopy data where measurement uncertainty varies strongly with wavelength. We introduce wSAM, an uncertainty- weighted extension of SAM that incorporates per-band observational uncertainty as inverse- variance …

Accurate mineral identification from hyperspectral satellite data is critical for efficient mineral exploration. Traditional one-class classification methods, such as OCSVM and Isolation Forest with data augmentation, often struggle to generalize across diverse spectral patterns, leading to low F1 scores despite high recall. In this study, we propose a metric learning network …

This monograph presents a GeoAI methodology for forecasting changes in agrarian structure, combining land and building registry (EGiB), real estate price register (RCN), and local zoning plan (MPZP) data on a regular hexagonal grid, on which a LightGBM model is trained to identify areas at risk of land parcelling or de-agriculturalisation. The methodology is validated on a case …

Reliable and accurate positioning underwater has been the goal of many research activities in the last years. In this paper, we present our design of a self-maintainable underwater navigation system, which provides a simple, low-cost, and flexible solution. In our concept, a set of buoys is equipped with Global Navigation Satellite System (GNSS) receivers as well as underwater …

This paper analyses the possibility of using integrated GPS (Global Positioning System) surveys and ground penetrating radar surveys to precisely locate damages to levees, particularly due to the activity of small fossorial mammals. The technology of intercommunication between ground penetrating radar (GPR) and an RTK (Real-Time Kinematic) survey unit, and the method of data …
