Superpixel and Supervoxel Segmentation Assessment of Landslides Using UAV-Derived Models
Reality capture technologies such as Structure-from-Motion (SfM) photogrammetry have become a state-of-the-art practice within landslide research workflows in recent years.

Zoneamento hierárquico da paisagem nos domínios da Bacia do Rio Uruguai / Landscape hierarchical zoning in the domains of the Uruguay River Basin [PDF]
This work presents an approach based on the combination of Geographic Information Systems (GIS) and Remote Sensing (RS) tools for the landscape integrated mapping within hierarchical zoning guidelines and Landscape Ecology principles.

Impact of the Scale on Several Metrics Used in Geographical Object-Based Image Analysis: Does GEOBIA Mitigate the Modifiable Areal Unit Problem (MAUP)? [PDF]
Using two GEOBIA (Geographical Object Based Image Analysis) algorithms on a set of segmented images compared to grid partitioning at different scales, we show that statistical metrics related to both objects and sets of pixels are (more or less) subject to the Modifiable Areal Unit Problem. Subsequently, even in a same spatial partition, there may be a

Using Geobia and Data Fusion Approach for Land use and Land Cover Mapping
Land Use and Land Cover (LULC) maps play an important role in an environmental modelling, and for many years efforts have been made to improve and streamline the expensive mapping process.

Benchmarking the Applicability of Ontology in Geographic Object-Based Image Analysis
In Geographic Object-based Image Analysis (GEOBIA), identification of image objects is normally achieved using rule-based classification techniques supported by appropriate domain knowledge.

Deep learning for land use and land cover classification from the Ecuadorian Paramo.
The paramo, plays an important role in our ecosystems as They balance the water resources and can retain substantial quantities of carbon. This research was carried out in the province of Tungurahua, specifically the Quero district. The aim is to develop

Abstract Tropical forests in sub‐Saharan Africa (SSA) harbor around one‐third of the world's species but are becoming more fragmented due to the expansion of human settlements and small‐scale agricultural (SCA) areas. This study systematically reviewed the approaches and methods used to analyze forest fragmentation and its impact on biodiversity in SSA,

Trait‐Based Community Assembly in Early Tropical Forest Succession
We found that in early tropical forest succession, dispersal (landscape forest cover), management (previous land use extent and duration), and environmental filters (understory light availability) collectively shaped community assembly, each playing distinct roles.
