It is What DDM-SVF Is and Is Not essentially a complete “geologic map Several attributes differentiate on disk” (CD-ROM). Because of its DDM-SVF from map-making systems digital format, the program contains on desktop computers (for example, far more data than even the most the Macintosh-based MiniCad maps complete analog maps. This digital developed by the Geological Survey of map offers several advantages over Canada (Peterson and Hanmer, 1992) hard-copy maps in that it simplifies and DOS-based systems, including finding samples (or units), makes GSMAP (Selner and Taylor, 1991) and information on map features and those of Ambroziak and Cook (1993). associated digital photos instantly First, it is a stand-alone application— available, and allows sequential that is, one needing no other software changes in thematic map type. to run.
