Assessing the Impact of Spatial Resolution and Hyperparameters on Automatic Agricultural Parcel Delineation Using the Segment Anything Model With Multi‐Resolution and Super‐Resolved Satellite Imagery

Transactions in GIS, Volume 30, Issue 4, June 2026.
ABSTRACT Accurate and automatic determination of the boundaries of agricultural parcels is essential for planning sustainable agricultural policies, managing agricultural production, tracking products and enabling precision farming applications. In recent years, pre‐trained visual base models with zero‐shot segmentation capabilities, such as the ...

Mechanisms of Vegetation Community Self‐Organization Driven by Water Availability in Arid Northwest China

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Precipitation is scarce in arid regions, making water redistribution a key driver of vegetation patterns, especially for non‐zonal vegetation in oases. Nevertheless, the coupling and mutual feedback mechanism between water and vegetation distribution is complex, and it has not been fully addressed. Taking an arid region of Northwest China as a

Assessing Land-Use and Land-Cover Change (LULCC) Between 2009 and 2019 Using Object-Based Image Analysis (OBIA) in Cameron Highlands, Malaysia

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Cameron Highlands has witnessed multiple land encroachment activities as well as repeated deforestation leading to extensive land-use and land-cover change (LULCC) over the last 6 decades. This is due to the heightened increase in demand for urban growth as well as agricultural activities and tourism industries.

Dissemination of Seagrass Density Information from Object-Based Image Analysis (OBIA) Mapping to Pengudang Coastal Community

Jurnal IPTEK Bagi Masyarakat
Pengudang Village, Bintan Regency, Riau Islands, is a coastal area that hosts seagrass ecosystems with high biodiversity. However, this area is increasingly experiencing degradation pressures due to climate change and anthropogenic activities. The limited public knowledge regarding the condition of seagrass ecosystems has become a major obstacle to ...

Object-Based Image Analysis of Downed Logs in Disturbed Forested Landscapes Using Lidar

Remote Sensing, 2011
Downed logs on the forest floor provide habitat for species, fuel for forest fires, and function as a key component of forest nutrient cycling and carbon storage. Ground-based field surveying is a conventional method for mapping and characterizing downed

Cross‐Border Land Tenure Detection With Satellite Imagery Data Using Siamese Neural Network: A Deep Learning Approach

Engineering Reports, Volume 8, Issue 4, April 2026.
Vector layer over raster layer. ABSTRACT Land disputes, particularly cross‐border issues, are a significant source of conflict in Ethiopia, where about 80% of the population depends on land‐based livelihoods and agriculture. These disputes significantly affect the rural population, whose primary source of income depends on land.
