A Survey of Geographic Information System and Image Processing Software - 1993

United Nations Environment Programme (1993)

Beginning in 1991 UNEP/GRID took up the task of conducting a biannual comprehensive worldwide survey of Geographic Information System (GIS) and Image Processing (IP) software system vendors in order to compile basic information about the overall state of the industry along with specific information about many of the software systems then available. The GRID Information Series Report No.18 published in January of 1992 contains the results and findings of this survey. This report, entitled "A survey of geographic information system and image processing software 1991" was published and distributed widely in developing countries and within the UN system. In keeping with the original intent of providing current updated information, the survey was repeated in 1993, and the results are presented here.
