Abstract
An important requirement in geographic information systems is the ability to display multi-scale data. Existing spatial access methods do not access multi-scale data efficiently and do not deal with all types of multi-scale data. To resolve this, an efficient spatial access method in multi-scale GIS is described. A performance evaluation shows that our method outperforms existing spatial access methods.
