This regulation includes: time and space transform of “big editor”and “small editor”; gear like linkup of thought structure and editing steps; three dimensional synchronous displacement of thought surface and spot.

Besides,the transformation between different types of land cover changed very frequently,and spatial location of the conversion was larger than the number of changes in the area,also concentrated in nansha area and northwest corner of panyu district,that near the center of Guangzhou city.

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.
