In fact, resources are scares and Open Source gives us the advantage of using these resources more efficiently; we are taking advantages from them to make our organization better with QGIS and PostgreSQL/PostGIS to migrate from Shapefiles to rows. Our methodology might be elementary but as far as we believe, not only we would like to share our experiences from our lessons learned; but also developing countries might have same problematic as us regarding to how to preserve their old heritage data. At the end, we would like to present our future long term objective related to the creation of a metadata portal for rational management and optimal use of this archiving system. This talk will gives audiences a basic concept related to data storage by using progressively FOSS4G. Keywords are PostgreSQL/PostGIS, QGIS and Shapefiles to rows.
