New perspectives to save cultural heritage
Altan, M. Orhan

CIPA 2003 XIX! 1 ' International Symposium, 30 September - 04 October, 2003, Antalya, Turkey
Figure 6. Query results
The results are shown in a table (fig.6) and it is possibile to
locate the results on the map. You must click on the record to
show and highlight the feature selected on the map (fig.7).

and the mapping application)
From this point users have the opportunity to use the above
described interface to interact with the map.
Another possibility given to a selected group of advanced users
is to manage the database or part of it, as shown in fig.9. Users
can visualize, modify and query all the information in the tables
they have the privilege to access. We built this functionality
using another open source application called phpMyAdmin. To
be able to use this tool you have to log-in (fig. 8). In the so-
called “advanced query”, specialists can use specific tools
developed for their own needs and this is very important in
order to achieve our goal, that is cooperation and interaction
with the advanced users. We want them to have the best query

If we consider the stand alone GIS realized in this project
[Ardissone 2003] and the shared tool that has been illustrated
above, it is evident that they don’t offer the same
functionalities. Let’s have a look at the differences. The two
systems offer the same functionalities to navigate and query the
map. The main difference in the Web application it is the lack
of some tools, such as distance measurement. The Web/GIS
application wants to be an instrument for sharing information,
so each tool needs to be designed by administrators in order to
make the site more closer to real users’ requests.
The condition and temporal queries aren’t yet fully developed
and they will be implemented in the future. At the moment
only more useful functions are available. The users can
interrogate the database in both applications. To be able to use
the Web\GIS application they have to be familiar with SQL
language, because at the moment there are no pre built masks.
However, they have the possibility of querying the whole
database, as they are using a normal DB management software
like MS Access. If we consider for instance the research of all
the castles the results are the same using the two tools (fig 10).
