Building Extraction Using Orthophotos and Dense Point Cloud Derived from Visual Band Aerial Imagery Based on Machine Learning and Segmentation

Remote Sensing, 2020
Urban sprawl related increase of built-in areas requires reliable monitoring methods and remote sensing can be an efficient technique. Aerial surveys, with high spatial resolution, provide detailed data for building monitoring, but archive images usually

Geoinformation systems in the field of agricultural land use

Zemleustrìj, kadastr ì monìtorìng zemelʹ, 2020
Agribusiness conditions in Ukraine are changing. Agricultural enterprises are actively restructured, change owners, attract investors and crisis managers. Management technologies that are currently used by most Ukrainian agricultural enterprises do not allow effective management decisions and create development plans that require objective and ...

A Random Forest–Based Global Gridded Model for Vertical Correction of Precipitable Water Vapor Accounting for Nonlinear Vertical Variation

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Vertical correction of precipitable water vapor (PWV) is a critical step in PWV fusion and atmospheric research. To address the limited accuracy of traditional global‐scale PWV vertical correction models that do not explicitly account for nonlinear vertical variations, we developed RF‐PWV, a global 1° × 1° PWV vertical correction model based ...

Detecting Irrigation From Spectral Differences Between Satellite and Modeled Soil Moisture Across the Contiguous United States

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Irrigation alters the terrestrial water cycle, yet its spatial distribution and temporal variability remain poorly constrained because existing data sets often rely on indirect proxies or inventories rather than observations tied to land‐surface water‐balance dynamics.

A Bayesian Hierarchical Spatiotemporal Model With Physical Barriers for Extreme Sea‐Level Prediction in Ireland

Environmetrics, Volume 37, Issue 6, September 2026.
ABSTRACT Rising seas raise the vulnerability of coastal regions through higher extreme sea levels. This paper estimates extreme sea levels at gauged and ungauged coastal locations around Ireland and the West Coast of Great Britain, using a Bayesian hierarchical extreme‐value model with spatiotemporal random effects. The annual maxima of tidal residuals

A Multidimensional Critical Regulation Approach to Water Resources Optimization

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Conventional water allocation models focus on reducing water shortage, maximizing economic benefits, and controlling environmental impacts, but rarely incorporate the coordinated evolution of multidimensional water systems. To address this gap, an integrated prediction‐simulation‐optimization framework was developed for 62 prefecture‐level ...
