Guidelines for the cartographic representation of the
continental Quaternary
The launch of activities of the Digitisation Work Group (GLI),
provided for under the programme agreement drawn up between the
National Geological Service (now APAT) and the University of Siena,
resulted in a series of requests for amendments and additions to
the Quaderni, serie III, n. 2 “Geological Map of Italy
— 1:50,000. “Cartographic representation guide”
and n. 6 “Geological map of Italy — 1:50,000.
Geological databank. Guidelines for the digitisation and
preparation for publication of databank” relative to
quaternary deposits.
As regards the cartographic representation, these requests
concerned the following topics:
- textural distinctions for various types of deposits;
- colours used for texture area symbols;
- introduction of new types of deposits;
- introduction of the concept of depositional environment with
relative representation;
- explanations relative to the use of abbreviations to represent
deposits;
- morphological elements.
The major changes introduced to the Quaderni in response to the
requests considered to be valid and therefore accepted –
following consultations with the Geological Committee – made
it opportune to draw up this summary. These guidelines are to be
considered binding for all sheets whose progress report allows
ongoing adjustments. Attempts will be made to uniform completed
sheets, evaluating whether adjustment is really impossible on a
case by case basis. Operators are asked to collaborate fully in
order to guarantee CARG project the necessary uniformity at
national level. This will require great coordination between
adjoining sheets and great efforts on the part of the Area
Committees.
All indications included in the guidelines published so far and in
the subsequent additions that are not modified by this document
shall continue to be valid.
