Related terms are multi-scale and multiple representation.
Multi-resolution can be defined as the concept of viewing or representing data at different levels of information content. A classic example is that spatial objects can have multiple geometric representations each associated with a predefined resolution level, where the different representations are either directly stored or dynamically created using dedicated generalisation methods. The construction of a base spatial database and the derivation of multiple generalised databases are more or less straightforward. The challenges, however, are to identify efficient models and methods for how to access and update existing data, integrate new data and at the same time maintain the multiple generalised versions in a consistent way.
