The main purpose of the present work is the development of an innovative WebGis graphical interface, related to Open Source (OS) Database Management System (DBMS), for the interpretation and the management of geodiversity features of the Sierra de Grazalema Natural Park (Andalucia, SW Spain). Located on the Betic Ranges geological framework, the study area shows a wide variety of geological and geomorphological elements, mainly consisting in spectacular exo- and endokarstic landforms. The identification, interpretation and appropriate representation of the major exokarstic forms have been carried out through photointerpretation and spatial analysis functions of OS Geographical Information System (GIS) and Digital Terrain Model analitic tools. Furthermore, the field detection allowed a better understanding of these karst morphologies and their correct positioning in the stratigraphical and geological regional framework. Due to the large proportions of the Park surface (53.411 ha), the smaller scale zone of Sierra de Libar (85 km²) was chosen as pilot study area, in order to check the feasibility and to improve the design of the main research. As a result, the large amount of these preliminary data collected for the Sierra de Grazalema Natural Park will be inserted into the PostgreSQL Database (DB) where spatial data are managed by PostGIS DB. PostGIS and PostgreSQL are OS DBMS, as well as all softwares used in the present project. These DB allow the management, implementation and exportation of data, particularly on the web. The aim of the project, in addition to the collection and characterization of the geodiversity, provides the possibility of divulging through WebGIS, all the 2D and 3D informations collected. The ability to show all the available data online, will be carried out through GeoDIV application, created ad-hoc for the project, using Mapserver OS application that allows viewing, querying and graphical output of spatial data. The continued implementation of the database will be directly linked to GeoDiv that will display automatically updates and changes to the database.

Abstract
The main purpose of the present work is the development of an innovative WebGis graphical interface, related to Open Source (OS) Database Management System (DBMS), for the interpretation and the management of geodiversity features of the Sierra de Grazalema Natural Park (Andalucia, SW Spain). Located on the Betic Ranges geological framework, the study area shows a wide variety of geological and geomorphological elements, mainly consisting in spectacular exo- and endokarstic landforms. The identification, interpretation and appropriate representation of the major exokarstic forms have been carried out through photointerpretation and spatial analysis functions of OS Geographical Information System (GIS) and Digital Terrain Model analitic tools. Furthermore, the field detection allowed a better understanding of these karst morphologies and their correct positioning in the stratigraphical and geological regional framework. Due to the large proportions of the Park surface (53.411 ha), the smaller scale zone of Sierra de Libar (85 km²) was chosen as pilot study area, in order to check the feasibility and to improve the design of the main research. As a result, the large amount of these preliminary data collected for the Sierra de Grazalema Natural Park will be inserted into the PostgreSQL Database (DB) where spatial data are managed by PostGIS DB. PostGIS and PostgreSQL are OS DBMS, as well as all softwares used in the present project. These DB allow the management, implementation and exportation of data, particularly on the web. The aim of the project, in addition to the collection and characterization of the geodiversity, provides the possibility of divulging through WebGIS, all the 2D and 3D informations collected. The ability to show all the available data online, will be carried out through GeoDIV application, created ad-hoc for the project, using Mapserver OS application that allows viewing, querying and graphical output of spatial data. The continued implementation of the database will be directly linked to GeoDiv that will display automatically updates and changes to the database.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
