Barbara J. Ryan, Director of the Group on Earth Observations.

The Group on Earth Observations (GEO) in Geneva – including 90 nations and 67 global science organisations – has sponsored two print runs of the D_City manifesto: the world’s first comprehensive ‘snapshot’ report on GEO’s vision to establish a global Earth simulations system.

Warmly received by several hundred geospatial scientists attending the latest International Society for Digital Earth (ISDE) conference in Kuching, Malaysia in September 2013, the D_City: Digital Earth | Virtual Nations | Data Cities report also is being commended by publishers and editors of the top three international geospatial trade publications (Geospatial World, Sensors and Systems and Apogeo Spatial), the science and development network (SciDev.Net), architecture book publishers Actar, and the quarterly journal for city governments (Cities Today). They are all supporting different aspects of the emerging ‘Science for Cities’ amd ‘Data Cities’ movement.

Shortly before the ISDE conference, GEO and the ISDE issued a joint media release announcing GEO’s approval of the report, which was co-edited by two founders-leaders of the ISDE’s digital cities working party, Davina Jackson and Richard Simpson. They collaborated on D_City (the ‘D’ being defined as ‘dynamic digital data design for decent development’) to help educate next generation urban development professionals about effective ways of using geospatial technologies.

The D_City report can be read and downloaded at It has been online since early 2012. The current update includes a ‘Postscript’ summary of latest advances supporting the GEO-co-ordinated ‘global Earth observations system of systems’ (GEOSS) project. These recent ventures include the International Council for Science’s Future Earth project and programs promoting cities and the emerging ‘space economy’ at the Organization for Economic Co-operation and Development.

Geospatial World has published an interview with D_City co-editor and ‘network catalyst’ Davina Jackson, on its ‘Asia Geospatial Digest‘ site.
