The image database DIoGeneS (Digital Images of Geologic & nice Structures)
provides an open web based portal that allows finding images of geological
structures held by the database. Initiated as an online reference collection
for studies done at the Geological Institute, ETH Zurich, it has grown to a
database with following aims: 1) to simplify structural identification, 2)
to serve the international geologists community as an interactive archive
and 3) to provide relevant information on individual structures.
The strength of this database, compared to search engines, is that the
images contain various geological attributes and consequently they are easy
to find by geological classification. Main attributes are scale, genetic
(natural or experimental structure), timing (primary or secondary
structure), rock type, structure and overprinted structure. Additional
attributes are shape, orientation, feature characteristics, interpretation
of structure and lithology. All these attributes can be searched with their
specific keywords (e.g.: Boudin, Fabric, Fault Fold, Foliation, Joint,
Layering, Lineation, Mylonite, Shearzone, Striae, Unconformity … in the
attribute structure). The resulting list, including previews, is sorted by
user selected attributes. By choosing one dataset, a full resolution image
is provided along with all attributes, detailed description of the
structure, sketch images and information of the of image owner
(photographer). Datasets can be alternatively searched by geological area
and free text search for the description. The location of the images is
shown in a map/satellite view. In addition all images are available as a
Google Earth overlay categorized by the main categories.
The attributes are explained with corresponding detailed geological
information to facilitate the use as an online reference for geological
structures. The image copyright stays with the image owner (photographer).
Contributions to the database are accepted from everybody in the geologist
community and can be done by electronic submission to the editorial board
that ensures the quality of images/structures.
DIoGeneS (www.diogenes.ethz.ch) provides a practical and open way of
identification of geological structures for students and it is an
interactive archive with relevant information on individual structures for
the international geologist community.
