We encourage the system administrators to locate all the system
behind a firewall, as shown in fig. 1. It’s important, indeed, to
protect all the data, cartographic and tabular as well, to
discourage crackers to download any kind of sensible
information.
3.3 Functionalities
The web site was built with Nuke technologies. Php-Nuke is a
php-made application used to construct and manage via web
portal systems. We decided to use it in the spirit of Open
Source philosophy. The portal let the user read news about the
“Marchesato di Saluzzo” Project, to take part in discussions, to
download data and so on. Our aim was to build an interactive
site for users interested in Cultural and Historical research.
The first function implemented in our project was the
possibility to navigate through the GIS application, fig.2.
Mapserver enables the user to view and query the vector data.
The first approach is to navigate on the cartography with user
friendly panning and zooming procedures.

The user can also highlight different layers according to the
scale of the view. Secondly, Mapserver lets you query the
feature you want to analize simply by clicking on it (fig.2). This
procedure query the dbf file associated with the shape vector
file. In this step we decided to not use MySQL server for
graphic queries because the MySQL support is still in beta
version and it’s not very stable.
The power of this system consists in the possibility to
interrogate the MySQL server through a user friendly interface.
It is possible to select the kind of feature (churches, cities,
castles...) you want to have information about and the
municipality where you want to focus your research (fig.4).
