In this paper a geomorphological GIS-based database was developed under the MapInfo Professional environment in order to systematically store information such as the exact coordinates and the corresponding fields of each geomorphological element. Apart from MapInfo's internal database, Microsoft Access was used as an external database, connected to MapInfo, through ODBC drivers. Paros island (Cyclades/Greece) was used as a case study. This island has a variety of morphological characteristics, many of them formed as a result of its complex lithological and tectonic structure that enforce differential erosion processes. All primary data of this geomorphological study were acquired via photointerpretation and fieldwork supported by the combined use of GIS and GPS in order to increase the accuracy and to speed up fieldwork. GIS also provided the opportunity for further spatial and quantitative analysis of the geographical database and the creation of a GIS - based geomorphological map
