Object-Based Image Analysis (OBIA) is a modern approach in remote sensing and GIS that focuses on analyzing imagery based on meaningful objects rather than individual pixels. Unlike traditional pixel-based methods, which classify each pixel solely based on its spectral values, OBIA groups pixels into homogeneous segments or objects that represent real-world features. This approach allows for the integration of spectral, spatial, textural, and contextual information, resulting in higher accuracy in complex landscapes, especially in urban areas, forests, or heterogeneous environments. OBIA is widely used in land cover mapping, vegetation analysis, urban planning, and _______ ____ ___ ____ _______ __________ ___ _____ __________ __________ ________.
