"The project GeoCID, in which the Island Government of Tenerife participates in the context of the European program INTERREG IIIB, aims to promote the popularization and the provision of geographical services to the citizenship creating value and achieving return on the investment in geographic information. A short introduction to the territorial context of the Island of Tenerife, Canary Islands, is followed by an outline of the conditions of the project, consisting of the implantation of the so-called geoportal GeoCID (www.atlastenerife.eu). The technological solution follows a top-down approach implementing INSPIRE principles adapted to Spanish legislation. The geoportal provides a web based catalogue and a map client which enables users to discovery and view geographic information. For the Government of Tenerife, the geoportal GeoCID is constituted as a transversal tool which allows the integral management of the life cycle of the geoinformation, from it's creation to it's publication."
