In this preliminary note, we describe our strategy for collecting, storing and representing new and old geological data acquired in several sectors of the central-eastern Himalaya where, since the 70's, researchers of the CNR- IGG Torino and the Department of Earth Sciences of the University of Torino addressed a significant part of their activity. All the geologic features (including rock samples, petrographic, petrologic and structural observations and measurements) are stored and harmonized in a suitable geodatabase using ArcGIS. Standard criteria are used to describe their typology and quality, facilitating future homogeneous data implementation and a correct data traceability. This geodatabase represents the fundamental starting point for the editing of a digital geological map of the central-eastern Nepal Himalaya.
