Introduction
complex requests and have immediate results. They can be
very useful for public authority, economic sector, scientic
research, students and teachers (for these laters as peda-
gogical resources).
There is an exponential growth of data related to the
geology of Algeria produced by different organizations,
universities, geological surveys and research centers. The
digitisation of these data allows a better organization for
their management which results in a substantial saving for
retrieval rates of speci
Algeria, the largest country in Africa with an area of
2,381,741 km
2
; contains a wide variety of geological and
geomorphological sites which are among the most signi
-
cant on the continent (Fig.
1
). The aesthetic quality of these
geosites makes their preservation as well as their promotion
for geotourism a major objective for the geoscienti
c com-
munity. Geoscientists have a great responsibility to help
decision-makers and local communities become aware of the
potential of these geosites. The sustainability of these geo-
resources will have long-term consequences for scienti
c information. Similarly, the use of
New Information and Communication Technology, i.e., the
publication online of these databases, helps to enhance
Algeria
cas
well as recreational activities.
In the last few years, the creation and management of
computer-based geological databases have become an urgent
requirement for both fundamental and applied research such
as mining geology, management of natural hazards, and
preservation of geological heritage. Databases, which allow
thematic mapping, involve a big amount of data (text, ima-
ges, tables,
le. However, at
this time, there is no such database, neither in public
domain nor among the university community, allowing
access to even the most important information on Algerian
geosites.
After describing several sites, the objective of this paper
is to provide a better sense of the quality and the geo-
graphical extent of
