INTRODUCTION Since a few years, Information Technology (IT) is more and more important in
geosciences and especially in volcanology. A Geographical Information System (GIS) is a great way to
organize and maintain your data for volcanology. GIS FOR VULCANO'S TEMPERATURE MEASUREMENTS
The purpose of the project is to create an internet resource which saves time to all researchers as it will
publish available and future temperature measurements of fumaroles. The base of the system consists
of interactive digital maps. Each map is a layer of the system. Each layer represents data for a date of
temperature measurements. The user can select in a menu one or more layers to be seen in the
interface. The background of all layers is the geological map of Vulcano Island or an aerial photo of La
Fossa crater. The temperature's evolution vs time can be seen too. During the same project, we develop
an add-on for Google Earth allowing a nicer interface to locate the fumaroles vents. Llinks between the
add-on and the web site exist to view the temperatures evolution of each fumarole. OUTLOOK OF THE
PROJECT A version of the project is already on line. The add-on can be downloaded too. This program
can be adapted for all volcanoes and a lot of kind of data (isotopic compositions, deformation,
epicenters location, etc.). It will run on and off-line. So you can have it on CD-Rom with your own data
to study them. An internet GIS can also be a source of information for the educated tourists and a base
to train local guides.
