Summary:
When spatial data is digitized for use in geographic information
systems and other software, information about its original scale,
resolution and accuracy is frequently lost. As a result, using such
information at different scales and combining it with data from other
sources may be difficult. Mapping vector data at smaller than the
original scale requires its generalization, which is usually handled
by post-processing in ways that are only weakly supported by
databases. The models and methods described in this book overcome
many such problems by providing a multi-resolution data
representation that allows retrieval of map data at a hierarchy of
scales, as well as documenting the accuracy of every spatial
coordinate.
