2.2. Hardware and Software Used
Following hardware and soflware were used to realize this
project.
Hardware: The server has got Intel SBT2 server board, two
Intel Pentium lll Xeon Processors, 512 MB ECC SDRAM,
and one HP-1120C printer.
Software:
Geomedia Professional 4.00.22
Oracle 9.2.0.1.0 Enterprise Edition.
3. RESULTS
This project has investigated three combinations of
geographic objects changes that require processing (table 1). .
graphic data | attribute data |
1 fixed changes
2 changes fixed
3 change change
Table 1. Combinations of change in geographic objects
First of all, a geographic database was constructed to
implementing this project. Then a *versioning" process that
adds a new line into database table for only the changed
object has been made. Thus the first version for graphic and
attribute data of geographic objects in a particular time was
achieved. After that when there were new temporal changes
in geographic objects new versions have been made. In this
paper it is accepted that displaying temporal changes on the
“mesceretipi (stand type)" geographic object has complicated
and intensive data structure in database.
Following examples are given to explain how these temporal
changes in both graphic and attribute data of “mesceretip!”
geographic object is edited, queried, and displayed.
While in 1964 geographic object stand type and stand number
were respectively CkKkKnbd3 and 5 (figure 1), in 1983 its
stand type was changed to Ckbd3. In this situation (version
2), this new stand type was the same as stand number 23 and
they have had to merged into one stand type (figure3). When
this attribute change were edited in revision set and then
committed. a new line was automatically added to database
table through database management system (figure 2, 4).

Figure 4. Database table representation of changes in 1983
Because of new situation (e.g. two same type neighbor stand
type) two stand types were merged by using GIS software
merge function (figure 5). After merge operation in revision
set and committing this change new version were created
(figure 6) and new lines were added automatically into
database table (figure 7).
