In order to meet the heavy demands in checking the data quality of national spatial database at the scale of 1 : 50 000, a novel method for automatic detection of the spatial conflicts based on the plane sweep algorithm was proposed.

The confirmation of spatial conflict is the key issue for detection and adjustment of spatial conflict.

This thesis is focused on the representation of spatial relations between a line and an area and its application to spatial conflict.

Distributed packet classification algorithm based on field conflict space

Applying the theory of relativity,the traveler movement was resolved into the traction motion and the relative motion,and the equation of the space motion of the traveler and the space position coordinate of the center of gravity of the traveler were obtained.

But, how to choose the oil-drop space position, time range, and data processing method are problems of primary importance.

This paper researched on the technical problems about the space location of laboratory and the attribution browse of laboratory based on the Web GIS network environment.

For those methods of image scrambling in positional space, there s still lack of effective methods to judge the scrambling effect and to give them a reasonable classification.

The study on positional space of rope tractive parallel mechanism was carried out in this paper.
