Scaling of interpretation with OBIA with backscatter data

, 2017
Multibeam Echosounder systems provide two datasets: a bathymetry grid and backscatter imagery. These can be combined together to produce an interpretation of these data using OBIA. The resulting interpretation divides the data into classes of similar attributes.

Multitask GLocal OBIA-Mamba for Sentinel-2 Landcover Mapping

Although Sentinel-2 based land use and land cover (LULC) classification is critical for various environmental monitoring applications, it is a very difficult task due to some key data challenges (e.g., spatial heterogeneity, context information, signature ambiguity). This paper presents a novel Multitask Glocal OBIA-Mamba (MSOM) for enhanced Sentinel-2
