9. How does a buffer operation transform a geographic representation?
Based on existing geometry (point, line, area) and attribute value(s), it cre-
ates a new area that represents a new geographic representation with a new
thing or event.
10. Why can't maps be transformed?
Maps cannot be transformed because of the cartographic representation
and recording in the fixed media of a map. Maps cannot be directly trans-
through digitization can, however, be transformed.

The second edition of this text contains a wealth of new and additional information,
but the first edition is still a classic. See

Assessment . Oxford, UK: Oxford University Press.
From the computer science perspective, this is a key topic documenting the develop-
ment of GIS:
