Sažetak
Object based image analysis (OBIA) may has evolved as a new paradigm in remote sensing and image processing. In this paper, we study some fundamental issues arising from the creation, handling, storage, and use of geographic information in an OBIA environment with a particular focus on LiDAR data. The research starts with a critical analysis of the multiplicity of scales in regard to ‘across- scale metrics’. It builds on the achievements a) from the ‘OBIA community’ and b) on the state of the art in GIS regarding discrete objects and fields. The paper investigates how objects are derived in various existing approaches and discusses the consequences of the object delineation methodologies and generalization effects.
