Detection of forest windthrows with bitemporal COSMO-SkyMed and Sentinel-1 SAR data
(2023-08-29)
Wind represents a primary source of disturbances in forests, necessitating an assessment of the resulting damage to ensure appropriate forest management. Remote sensing, encompassing both active and passive techniques, ...
Land-Use Dynamics and Water Quality in Andean Basins
(2023-11-15)
Conventional agricultural practices, such as the use of agrochemicals, implementation of monocultures, and the expansion of crops in strategic ecosystems, have significant impacts in Andean basins, directly increasing ...
Multiannual Change Detection in Long and Dense Satellite Image Time Series Based on Dynamic Time Warping
(2024-07-22)
High-resolution (HR) satellite image time series (SITS) are a valuable data source for analyzing land cover change (LCC) due to their large amount of spatial, spectral, and temporal information. However, most existing LCC ...
Land cover classification of Andean sub-basins in Colombia based on Sentinel-2 satellite images and deep learning
(2023-06-15)
The Las Piedras River sub-basin, located in the department of Cauca, Colombia, is very important for the region, especially for the capital (Popayán). This is because this sub-basin contributes around 68.17% of the water ...
Impact of land cover variations on the Morroa aquifer (Colombia) static and dynamic levels through remote sensing analysis
(2024-06-10)
The Morroa aquifer plays a crucial role supplying drinking water to around one million residents across Sucre, Córdoba, and Bolívar departments in Colombia. However, it faces severe water stress, ranking as the second most ...
Mapping dispersed houses in rural areas of Colombia by exploiting planet satellite images with convolutional neural networks
(2023-06-15)
The Sustainable Development Goal (SDG) number 11 aims at making cities and human settlements more inclusive, safe, resilient, and sustainable. Complying with SDG 11 is a difficult task, especially when considering rural ...
Windthrows Detection With Satellite Remote Sensing Data: A Comparison Among Sentinel-2, Planet, And Cosmo Sky-Med Data
(2023-10-20)
Wind disturbances represent a great source of damage in forests, and an assessment of such damage is very important for adequate forest management. Remote sensing is an effective tool for this purpose and can be used by ...
Fire Scars Mapping Over Brazilian Amazon Forest by Exploiting Sentinel-2 Data and Deep Learning
(2024-07-12)
Wildfires in the Brazilian Amazon have raised significant concerns owing to the environmental, social, and global impacts associated with these events. They have led to habitat loss for various species and release of ...
Multitemporal Analysis of Inland Water Bodies in the Context of Water Security: A Colombian Case Study
(2024-07-11)
This paper presents an analysis of two inland water bodies, Salvajina Reservoir and Sonso’s lagoon, located in the Upper Cauca River Basin, Colombia. Such analysis is carried out in the context of Water Security (WS) by ...
Rapid Mapping of Waterbody Variations in the Central Rift Valley, Ethiopia, Using the Digital Earth Africa Open Data Cube
(2023-10-20)
Mapping waterbodies variations through time is only possible thanks to the use of in-situ hydrometric sensors or remotely sensed data. Few areas around the world count with a functional in-situ sensor’s network, but all ...
