The International Gravity Field Service (IGFS) Central Bureau (CB) has recently been established at DGS/AUTH and one of its main activities has been the promotion of IAG gravity-field related services along with the development of a new, user-friendly website. One critical issue that needs to be incorporated by IGFS is to answer user needs in terms of providing reliable feedback as to what kind and what type of gravity-field related data one can retrieve from IGFS. With that in mind, IGFS has developed a dedicated gravity-field related geoportal with the sole purpose of organizing a modern, user-friendly and coherent one-stop point where the interested user can visualize the current data availability within BGI, ICGEM, ISG, and IDEMS. The developed geoportal is incorporated as an IGFS application within the dedicated IGFS application server using open-source solutions (GeoServer, OpenLayers, PHP, PostgreSQL) and the GSSH coastline for the presentation of a basic cartographic background. The geoportal itself is not intended to provide the data themselves, but it rather serves as a one-stop point for showing data availability and directing to the respective IAG service for data retrieval. In this work the main steps taken for setting up the server are outlined along with some examples of the available data and information that the user can retrieve.
