Estimating Afforestation Area Using Landsat Time Series and Photointerpreted Datasets

Remote Sensing, 2023
Afforestation processes, natural and anthropogenic, involve the conversion of other land uses to forest, and they represent one of the most important land use transformations, influencing numerous ecosystem services. Although remotely sensed data are commonly used to monitor forest disturbance, only a few reported studies have used these data to ...

Marine litter can shift sea turtle nests toward the shoreline

Oikos, Volume 2026, Issue 6, June 2026.
Marine litter is an emerging threat to sea turtle rookeries, yet its effects on nesting behaviour remain poorly understood. In this study, we investigated how macro‐litter accumulation on beaches influences the spatial distribution of loggerhead turtle Caretta caretta nests on Boa Vista Island, Cabo Verde.

New Paradigms for Geomorphological Mapping: A Multi-Source Approach for Landscape Characterization

Remote Sensing
The advent of geomatic techniques and novel sensors has opened the road to new approaches in mapping, including morphological ones. The evolution of a land portion and its graphical representation constitutes a fundamental aspect for scientific and land ...

Fracture of Podolia caves in the aspect of rotational and tectonic causes of formation

Геофизический журнал, 2012
Problems of origin of speleoinitiating fracturing of Podolia cave networks are discussed applying structural analysis of labyrinthes, photointerpretation relief lineaments and conception of planetary (rotation-initiated) fracturing.

Semiautomated classification of units in volcanic terrain based on three morphometric attributes derived from a digital elevation model (DEM)

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
The proposed method better responds to the needs of detailed cartography improving the working scale (local and regional) representation; also roughness attributes facilitate the identification of geomorphological units, and the DEM generation method enhances terrain representation.

Fotointerpretación geomorfológica del curso bajo el río Grande de Santiago, Nayarit

Investigaciones Geográficas, 1979
The principal geomorphologic modifications of the fluvialbed and their effects are analized in the low course of river Grande de Santiago, in the last 37 years, through the comparative photointerpretation of aerial images taken in different dates.

Water regimentation in the Pontine Plain between Astura and Fogliano in the dynamics of ancient population

Groma, 2020
The stretch of coast between Astura and Fogliano is characterized by a particular geomorphological situation linked to several difficulties in the drainage of the waters that have always generated marshes.

Relations entre la densification du bâti et la rigidification du trait de côte dans le nord du Nouveau-Brunswick (Canada) : l’exemple du territoire de la Commission de services régionaux Chaleur

VertigO
The increasing use of hard coastal defenses (HCDs) by private property owners is a growing concern for the Chaleur Regional Service Commission (RSC-Chaleur), a regional organization responsible for managing coastal areas.

Evaluating methods for high‐resolution, national‐scale seagrass mapping in Google Earth Engine

Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 292-304, April 2026.
Marine habitat mapping using satellite imagery can provide baseline and monitoring data across large spatial scales and in remote locations globally. This study evaluates how key methodological choices influence the accuracy of open‐source (for non‐commercial use), cloud‐based satellite mapping workflows for seagrass meadows in the Maldives.
