The guide will discuss some
of
the standard functionality
of
the Apple Newton, and will
provide the user with a manual for the RIA
MapPad and AGSO FieldPad software. The
Newton can be switched
off
anywhere in its programmes and on rebooting, will return to
the last screen. Programmes are exited by pressing the
I&l
button in the bottom right
of
the
screen.
The OZROX database structure
The OZROX Field Geology Database has seven main data tables; SITES, OUTCROPS,
SECTHOLES, INTERIZONS, ROCKS,
LITH DATA and STRUCTURES. Currently, the
SECTHOLES and INTERIZONS tables are not accommodated by the FieldPad structure.
All other tables indicated in Figure 1 below are lookup or authority tables used to validate
the classifications and nomenclature used in the main
OZROX tables.
The hub of the field database is the SITES table which standardises the way point location
data are recorded and ensures that the accuracy and lineage
of
coordinates are noted. This
is logically linked to the
OUTCROPS and ROCKS tables via the Originator Number and
Site ID. The
OUTCROPS table stores data at the outcrop level and includes links to the
STRATDAT biostratigraphic database. The
ROCKS and LITHDATA tables record
lithologies and samples descriptions. LITHDATA is an expandable attributes table for
further descriptions of the lithologies and samples described in the
ROCKS table.

many-to-one linkages. The rounded boxes represent databases
used to validate the data in
