Abstract
Geographic information systems must frequently present query
results in graphical form. Generally, these graphical
representations are not in a single, standardized form, but are
influenced by the user's individual or corporate working
environment. The user may manipulate the graphical representation
of query results-not the content of the database-to present the
same query result in various ways. Complementary operations are
necessary to examine the graphical representation. This dualism
between manipulation and examination is investigated and the
incorporation of these operations into a human interface is
demonstrated.
