摘要：Since the moment Google Earth launched by Google company, the subject of geographic information system (GIS in short) has made great progress. While, the traditional two-dimensional and three-dimensional power transmission lines GIS can no longer satisfy people's requirement to understand the real world. This paper is based on GeoGlobe digital terrestrial platform.It requires some fast scheduling data method. Because the data organization and management methods in the traditional 3D transmission lines GIS are no longer suitable according to the requirement of data scheduling in the digital earth theory, it is necessary to put forward a more reasonable and conformable data structure to implement clipping data scheduling.This paper aims to discuss and resolve the problems mentioned above, and then establish a modal database for the use of Digital Earth
