Hi guys,
In a lot of the literature about GIS, (for example on www.gis.com and the MapInfo Professional user guide), it mentions that 80% of all data could contain a spatial reference. However does anyone know how this figure was reached? Was any research done into data and the potential for spatial referencing to come up with this or is this figure just marketing blurb that sounds "right"?
Its a nice catchy figure, but I cant really go round quoting it in papers and so on unless theres some justification for it.
