The Nextdata Project aims at developing a national standard methodology for the recovery, storage, access and dissemination of environmental and climate data of mountain and marine areas. The Earth and Environmental Sciences Department of University Milano Bicocca has the task to create and manage a geo-database for glacier data and for non polar ice core drilling data. In particular the archive will store chemical and physical measures of current ice cores, data produced by numerical simulations and measurements made during the project. The working environment is based on open source structure: S.O Ubuntu GNU/Linux 12.04 LTS server with implementation of FTP, SSH, Apache Tomcat services and PostgreSQL with PostGIS extension for geospatial database. The realization of the geo-database came from careful analysis of available data and information, trying to create an upgradeable, flexible and adaptable structure. The main aspect of the database is the geographic component. The algorithm of the relational model allowed to identify main entities with their attributes and relationships between them. The peculiarity of this relational model is given by the interpretation of the numerical values, derived from chemical and physical characterization of ice cores, which are separate entity stored in the database. The observance of entities indipendence principles allows a better description of stored informations, reducing redundancy and increasing their standardization. The possibility to store vector geometry provides the next step of the project. Results will be disseminated through a WEBGIS platform. In this way, users can view and download spatial data and their attributes. Futhermore, the storage and display of metadata is also entrusted to the Geonetwork opensource application. Finally the geospatial services technical specification will be those proposed by OGC (Open Geospatial Consortium) and INSPIRE directive in order to maximize data interoperability.
