In recent years, with the development of laser scanning technology, three-dimensional model from laser scan range data is extensive applied in the fields of digital ancient building, preservation of cultural relic.

The data depth is a new data analyzing technique, using which can make data analyzing and processing and obtain usable and creditable information, providing reliable accordance for policy-making.

In this paper,sphering method is used to revise the data depth based on spatial rank.

This paper presents a general data depth function with adaptive shape of deep contours based on Gaussian kernel function.

This article analyzes the concept of resource collection,the metadata standard available for resource collection and the relations between resource collection and resource object,believes that resource collection is also a kind of resource object and suggests that we should use metadata depth me.
