Comment on Rodríguez Collantes et al. A New Earth Crustal Velocity Field Estimation from ROA cGNSS Station Networks in the South of Spain and North Africa. Remote Sens. 2025, 17, 704
Abstract
In their recent study, Rodríguez Collantes et al. presented a new GNSS velocity field from the Royal Institute and Observatory of the Spanish Navy (ROA) network, deployed in southern Spain and northern Africa. However, their claims regarding the novelty of certain results and the precision of their findings compared to recent publications are questionable. I present previous studies not cited by the authors, which challenge or contradict these claims and suggest potential bias in their study. Based on these publications, I highlight key differences, contradictions, and shortcomings in aspects such as the GNSS data used, time series analysis, methodological rigor, and geodynamic interpretation. Furthermore, I identify significant errors in both graphical and numerical results, issues affecting the replicability of the methodology, and inconsistencies between the text and its citations.
