Abstract

"Magnifier" is a multi-scale display form of electronic map which can display more important areas with more details and less important areas with fewer details. In order to implement magnifier, different part of the screen must display data of different scale, so mathematical basis, data organizing, display management all have to be improved. This paper discusses the implementation of magnifier on the aspects mentioned above and does some experiments.
