Classical geologic mapping is one of the main techniques used in geology where pencils, paper base map and field book are the traditional tools of field geologists.

The work started in the lab by implementing themes for defining a cartographic base (aerial photos, topographic and geologic maps) and for field work (developing symbols for outcrops, dip data, boundaries, faults, and landslide types). Special prompts were created ad hoc for data collection. All data were located or mapped through GPS. It was possible to easily store any types of documents (digital pictures, notes, and sketches), linked to an object or a geo-referenced point. Immediate thematic categorization of mapped objects, correct dimensions and positions allow to collect, interpret, and interpolate all data directly in the field. After field, the lab work was carried out keeping data separate from interpretation thanks to database opportunities. Finally, the geological map was interpreted in order to draw geologic sections and to build three-dimensional geologic model of the area.

Abstract

Classical geologic mapping is one of the main techniques used in geology where pencils, paper base map and field book are the traditional tools of field geologists. In this paper, we describe a new method of digital mapping from field work to buiding three dimensional geologic maps, including GIS maps and geologic cross-sections. The project consisted of detailed geologic mapping of the are of Craco village (Matera - Italy). The work started in the lab by implementing themes for defining a cartographic base (aerial photos, topographic and geologic maps) and for field work (developing symbols for outcrops, dip data, boundaries, faults, and landslide types). Special prompts were created ad hoc for data collection. All data were located or mapped through GPS. It was possible to easily store any types of documents (digital pictures, notes, and sketches), linked to an object or a geo-referenced point. Immediate thematic categorization of mapped objects, correct dimensions and positions allow to collect, interpret, and interpolate all data directly in the field. After field, the lab work was carried out keeping data separate from interpretation thanks to database opportunities. Finally, the geological map was interpreted in order to draw geologic sections and to build three-dimensional geologic model of the area.
