[Termes IGN] système d'information géographiqueRésumé : (Auteur) Organisations are run by data; they collect them, analyse them and, from these analyses, determine how they might be run more effectively. In the 1980s, as more organisations adopted geographic information systems, it became known that the cost of the hardware and software needed for a GIS often represented only approximately 30 per cent of the final costs of implementing the GIS project ; the majority of the budget was being spent on data collection and conversion. These percentages are changing as the commercial data market starts to operate efficiently in the GIS arena. The 70:30 ratio is now only representative of high value, low volume situations involving start-ups of operational systems such as utilities. It is estimated that between 60 and 80 per cent of all data held by government departments can be classed as geospatial, where this is defined as any data that have associated with them some geographical referencing, including to a national grid, a postcode system, latitude/longtitude or defined areas such as parliamentary constituencies. As government and private sector organisations realised the huge investment they were making in the collection of data, the organisations' accountants started to assess the advantages and disadvantages of allowing others to use the data that had been collected by their organisations as against using data created by third parties. This chapter explores the emergence of the commercial geoinformation data publishing market and considers its future.
