Abstract

It is troublesome to set the display parameters of every feature class in feature-based zoom view. In order to solve that problem mentioned above, this paper used some data to verify raster-based map information measurement, expanded raster-based map information measurement to vector map, and then discussed how to use information amount to automatically control feature classes' display or not, rather than setting all kinds of display parameters in advance. That adaptive visualization technology would dynamically calculate the current information amount in map view. If the current information amount was below the minimal allowance value, the more detailed feature class would be overlaid on view. The technology presented in this paper was more adaptive than that technology to set display parameters beforehand.
