First data delivery was in June 1983, consisting of 57 maps and 1.24 million points. By the end of 1985, Geodat had delivered twenty million data points and 750 map sheets in the 1:50,000 to 1:250,000 scale range. Alongside mainstream production for the project sponsors, the Geodat project produced a complete digital map of the world at a scale of 1:1,000,000, MundoCart, in 1985. MundoCart was based on digitisation of paper prints of the United States Defense Mapping Agency's (DMA) Operational Navigation Chart (ONC) 1:1,000,000 scale paper map series, produced by the US, Australia, Canada, and the United Kingdom. ONC charts were designed to meet the needs of pilots and air crews in medium-and low-altitude navigation and to support military operational planning, intelligence briefings, and other needs. Some 270 1:1million maps, plus six 1:2million maps for Antarctica, resulted in 30 million data points. MundoCart provided numerous commercial and academic Geographic information system (GIS) users with their first complete vector map of the world. The data was sold, along with a complete set of FORTRAN mapping software, by Petroconsultants (CES), a UK subsidiary of Petroconsultants SA, subsequently sold to IHS in 1996, that sponsored the project.
