David J. McCraw grew up in Charlotte, North Carolina with a keen interest in places, landscapes, maps, and the arts. He played many musical instruments poorly (guitar, trumpet, french horn), was very active in theatre (Charlotte Childrens Theatre, high school theatre) before deciding to pursue earth scientific interests. In the summer of 1980, he participated in a cooperative education position at the U.S. Geological Survey, Geographic Names Information Management division, helping develop the GNIS database. He recieved both the John Bowley Derieux Research Award from the North Carolina Academy of Sciences and the W. A. Tarr Award for meritorious work in the Earth Sciences from Sigma Gamma Epsilon for his undergraduate thesis, and graduated from the Geography and Geology program at Western Carolina University cum Laude in May 1982. He then graduated with a M.A. in geography from the University of New Mexico, and presented his masters thesis on the historical invasion of creasote bush in southwestern NM at the Southwestern Division of the American Association for the Advancement of Science in Tucson, Arizona in 1985. Since receiving his M.A., he has actively continued research in physical geography and has worked as a cartographer. At the Louisiana Geological Survey, he helped produce 6 color geologic maps and a 100+ page atlas of historical shoreline changes of the Louisiana coastal barrier islands, 1851-1990, for the U.S. Geological Survey. In 1995 he returned to New Mexico and was employed by the New Mexico Bureau of Geology and Mineral Resources as a Cartographer II. In 1997, for his active role in helping develop the Bureau's digital geologic mapping program, STATEMAP, he was promoted to GIS Cartographer. While not trained in GIS, he has been very proactive in the New Mexico geographic information technology community. He has served on the Board of Directors of the New Mexico Geographic Information Council since 1998 and as President from 1999 to 2001. In addition, he actively participated in the resurrection of NMs state government GIS Advisory Committee in 1999 and has served as a voting member since then. In 2001, he was promoted to Senior Geological Lab Associate to assist in the management of the Bureaus geologic mapping program.

The issue of GIS certification has been growing since the mid 1990s, originating from 3 main sources: 1) the certified and licensed surveying profession via the National Council of Examiners for Engineering and Surveying (NCEES), 2) the International Organization for Standardization (ISO), and 3) GIS academicians. Controversy surrounds the issue, often fueled with reactionary sentiment, to the point that it is not always clear exactly what is being implied by the term GIS certification: certification of GIS practitioners (people), or certification of GIS data. Some form of certification of GIS technicians is imminent, likely in the form of a national examination of basic GIS skills, as well as add-on skills pertinent to specific disciplines that utilize GIS. This is a potential problem for geological GIS personnel since they most often are required to have a working knowledge of many fields (geology, pedology, geography, environmental science, natural resources).
1999, Cant see the geology for the ground cluttershortcomings of the modern digital topographic base: in: Soller, D. R., ed., Digital Mapping Techniques 99 Workshop Proceedings, USGS Open-file Report 99-386, p. 21-26.
Digital base map data of modern geologic maps must comply to the requirements of the National Spatial Data Infrastructure by containing the following framework data layers: transportation, hypsography (elevation data), hydrography, political units (boundaries), geodetic control, and a cadastral reference system, e.g., PLSS. At the onset of digital mapping a decade or so ago, overall quality of digital base data was quite poor compared to the non-digital, photographic plates previously used in traditional cartographic methods, and it has never adequately improved. These digital geographic base data are currently available from the USGS in 4 basic formats: DOQs, DEMs, DLGs, and DRGs. DOQs and DEMs are best utilized in conjunction with DLGs or DRGs due to a lack of several types of framework data. Only the DRG contains all necessary framework elements, yet it is not available in high resolution. A case study from a high relief area with a small contour interval clearly illustrates the overall poor quality of this scanned data. All 4 datasets require extensive modification prior to incorporation into the geologic map. The best solution at present is to generate in-house DRG data by scanning photographic plates at much higher resolution and rubber-sheeting the raster image around the 16 basic grid control points in Arc-Info.
To provide the public with prompt releases of new geologic and hydrologic map information (primarily STATEMAP quads funded by the NCGMP), the New Mexico Bureau of Mines and Mineral Resources (NMBMMR) has developed a new series of open-file digital geologic quadrangle maps (OF-DM). The maps are designed to address compelling socioeconomic issues (water supply and quality, geologic hazards, land-use planning, mineral resources) and basic scientific problems. The geologic maps will be available in 3 formats: a) multicolor inkjet plots complete with cross sections, unit descriptions, and correlation charts; b) a collection of ARC-INFO coverages for GIS users; and c) digital Postscript files of OF-DM plots.
After the geology is compiled in ink on a greenline mylar stable base, it is scanned at 100% at 400 d.p.i. on an INTERGRAPH ANATECH large-format drum scanner that drops out the greenline base map while holding all inked geologic linework (contacts, structures, and symbology). Geo-referencing tick marks are generated in ARC-INFO and then exported as an Adobe Illustrator file along with a TIFF image of the map to Macintosh Macromedia FreeHand, where the linework is drafted, unit polygons are assigned CMYK colors, and type is set. This process essentially eliminates introduced digitizer-operator error, and produces smaller digital files that contain lines with smooth curves made from a minimum number of points (nodes) and type of offset-printing quality. The drafted linework is then exported as individual layers for all individual line attributes as DXF files to ARC-INFO, where they are converted into ARC coverages for GIS users. The completed geologic map FreeHand file is then registered to a TIFF DRG quadrangle base (which has been cleaned in Adobe Photoshop and turned transparent in FreeHand) and is exported as a Postscript file to Image Alchemy, which rasterizes the file for inkjet plotting on demand.
By producing these OF-DM maps through the combined interaction of NMBMMRs [NMBGMRs] Macintosh-based cartography and ARC-INFO-based GIS sections, the public is provided paper and digital products of a superior quality to those developed solely from these individual platforms. In addition, this process has increased NMBMMRs [NMBGMRs] cartographic production efficiency, and map upgrades to the peer-reviewed Geologic Map (GM) series, printed by offset press, can then be easily made.
