This document summarizes a presentation on implementing hackable user-driven geographic information (GI) services within spatial data infrastructures (SDIs). It discusses lessons learned from services like Google Maps, including their use of publicly available geospatial data. The presentation proposes developing open standards-compliant application programming interfaces (APIs) to allow non-experts to build customized GI services using SDI data. Requirements for such APIs are outlined, and examples from Italian regions are provided. Standards that could be implemented are listed.

Lessons learnt: Google/Yahoo/ On February 2006 Jo Walsh wrote (): ( Google Maps / Earth and now MSN Live Local have been big drivers for public awareness of digital mapping and location technology. All of those services make some use of publically funded, state-collected geodata (mostly in state- aerial imagery). Google Maps got so much interest because it was so ''hackable'; developers with no hackable'; cartographic knowledge at all could build their own services on top of it, augmenting it from public-domain- public-domain- derived utilities like http://geocoder.us () Walsh J., EGIP Mailing list, 27 February 2006 http://egip.jrc.it/200602/1561.html 22nd June 2006 12th EC-GI&GIS Workshop Innsbruck 2006 EC- 3 / 17
