摘要：This paper highlights recent developments that have led to object-based image analysis (OBIA). We summarize major trends in bridging remote sensing, image processing and GIS and we hypothesize that OBIA is an emerging paradigm in image analysis. We identify two initial foundations for this paradigm shift, namely the advent of high resolution satellite data and the market entry of a commercial OBIA software package. Timewise, these developments fell on fertile ground and were accompanied by other, more sectoral approaches to cope with new requirements in automated image processing, analysis and interpretation. An increasing demand for geospatial information in the light of environmental pressure and monitoring needs has catalyzed the development of new methods to exploit image information more intelligently. Beyond an overview on the development of OBIA we briefly pinpoint some challenges that – from the authors' view – arise in the retinue of the upcoming paradigm
