A Spatiotemporal Ontology of Informal Settlements Using a Combination of OBIA–RF With Worldview-3 and Landsat Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
An understanding of the spatial distribution of informal settlements within a city is important for urban management decision-making and service infrastructure provision, provides useful information for planners and policymakers, and has a role in ...

Tracking savanna vegetation structure in South Africa by extension of GEDI canopy metrics with Landsat, Sentinel-2, and PALSAR

Science of Remote Sensing
Adaptive management of savanna ecosystems requires frequent monitoring of woody vegetation structure, and although vegetation structure and changes may be captured with repeat airborne lidar, it is spatially and temporally limited across African savannas.

A 2020 forest age map for China with 30 m resolution [PDF]

Earth System Science Data
A high-resolution, spatially explicit forest age map is essential for quantifying forest carbon stocks and carbon sequestration potential. Prior attempts to estimate forest age on a national scale in China have been limited by sparse resolution and ...

Long-Term Forest Disturbance Mapping in the Qinling Mountains Using Landsat–Sentinel Annual Composites: A Regional Assessment of LandTrendr Performance

Remote Sensing
Forests in the Qinling Mountains play a critical role in maintaining regional ecosystem services, yet long-term, high-resolution forest disturbance datasets at the regional scale remain limited, particularly in mountainous and cloud-prone environments ...

Leveraging machine learning and Landsat time series for high-resolution mapping of mining-induced vegetation changes in Ouagadougou, Burkina Faso

Environmental Challenges
Quarries are open pit mines, where construction materials such as granite and clay are extracted from the earth's surface, leading to a major disturbance of vegetation and subsequent degradation of ecosystem services.

A Novel Framework for Long-Term Forest Disturbance Monitoring: Synergizing the LandTrendr Algorithm with CNN in Northeast China

Remote Sensing
As carbon cycling and global environmental protection gain increasing attention, forest disturbance research has intensified worldwide. Constrained by limited data availability, existing frameworks often rely on extracting individual spectral bands for simple binary disturbance detection, lacking systematic approaches to visualize and classify causes ...
