Former environmental evolvement and environmental archaeological research results can be summed up into 4 aspects： 1） Formation and evolution of the Taihu Lake; 2） Transgression and sea-level changes in the Holocene epoch; 3） Reconstruction of the pre-historical environment; and 4） Impacts of environmental variations on the rise and fall of human civilization （formation of the cultural interruptions）. Based on this review, some limitations in the present research methods and possible outcomes are pointed out in this paper.展开更多

Apart from non-shape information, such as age, material, etc., the model also consists of shape information and shape feature information. Shape information is collected by Lasers Scanner and geometric modelling techniques. Feature information is generated from shape information via feature extracting techniques. The model is used in an integrated storage, archival, and sketch-based query and retrieval system for 3D objects, native American ceramic vessels. A novel aspect of the information model is that it is totally implemented with XML, and is designed for Web-based visual query and storage application.展开更多
