Abstract Remote sensing technology has found a wide range of applications in the new round of national island investigation. On
account of the deficiency of visual interpretation,the object-oriented approach was adopted in this paper to extract island
thematic information. For multi-source,multi-resolution data and multi-temporal high resolution optical data,different
strategies were adopted to detect small objects and eliminate false information. The experiment results show that the proposed
methods give a fine performance in both recognition capability and recognition accuracy.
