in plane coordinates in UTM-WGS84 format. No other type of
conversion is performed in order to minimize errors.
For this reason, all the maps, as previously said, are
georeferenced in the UTM-WGS84 system through an accurate
GPS survey.
In moving map state (Fig. 13) the application also show the
position of the visitor on the screen, moreover an option permits
to visualize labels relating to each feature area of some interest.
5. CONCLUSIONS
The application still requires a period of test to make it more
user friendly. The buttons on pocket PC can be used to perform
some simple actions as starting the navigation, re-launching the
instructions about an area or stopping the message.
Today, the test on the use of the software application, showed
here, is carried out in the archaeological site of Monte Jato.
But there are some important activities to carry out :
* to realize of an open G/S support for managing the
geodatabase.
* to carry out some other tests on many other GPS
systems (of bluetooth type or applied to a pocketPC
by a jacket), checking the accuracy of positioning in
relation to the chip used to build them, also looking
for the less expensive GPSs.
® to better investigate the possibility to standardize the
description of archaeological sites by GIS, also for the
virtual fruition through a WEB-GIS system.
The global aim is to extend the use of the system to all open
archaeological sites of Sicily.
