Data Description
  Abstract: This data set consists of one TIFF image, one JPEG image, and one PDF map of bouguer gravity and residual bouguer gravity covering most of northern mainland Nova Scotia. The total field bouguer gravity and residual bouguer gravity map images were produced from data contained in Nova Scotia Department of Natural Resources Open File Report 1995-005. Gravity station spacing is variable throughout the map sheet and artifacts related to station spacing may be present in the final map image. The total field data set contains the cumulative measured response from surface features to upper crustal sources. The residual gravity image was derived from the total field data by subtracting long-wavelength (~> 8-10km) signal from the total field data to enhance near surface (< 5km) features. Station spacing restricts grid cell size to 500m with a 8000m blankng distance, which restricts near surface spatial resolution in the published map image. The 24-bit colour images were produced with a 25m pixel size. Shading was from the southeast at 35 degrees above the horizon. For complete details an Open File Report will be forthcoming from M. S. King later in 2004. The images were produced by contractor M. S. King using funds provided under the Natural Resources Canada and Nova Scotia Department of Natural Resources joint project 'Mapping, Mineral and Energy Resource Evaluation, Central Nova Scotia', part of Natural Resources Canada's Targeted Geoscience Initiative (TGI-2) 2003-2005.
  Purpose: The purpose of this data set was to enhance the level of geological knowledge in the Targeted Geoscience Initiative (TGI-2) project area.

  Technical Prerequisite: In order to view our digital files on your computer, you require mapping software (e.g. ArcGIS(R), ArcInfo(R), ArcView(R), MapInfo(R), AutoCAD(R)). If you do not have this software, ESRI* provides a FREE Map Viewer called ArcExplorer(R) which you can download over the Internet. ArcExplorer(R) works with our "E00", "SHP", "JPG", "SID" and "TIF" files. The "TIF" and "JPG" image file formats can be viewed in a number of graphics and image packages including CorelDraw* and Paint Shop Pro. The MRSID "SID" images can be viewed in an increasing number of image packages as well as with a FREE MRSID viewer supplied by LizardTech*. In order to use the E00 format data you need to download both ArcExplorer(R) and the ArcExplorer(R) Import Utility (Import71.exe). The import utility is required to convert the ArcInfo "E00" files into ArcInfo coverages, which then can be viewed in ArcExplorer(R). In order to view our PDF files on your computer, you will require a PDF Viewer (e.g. Adobe(R) Acrobat(R) Reader). If you do not have this software, Adobe(R) provides this software, Adobe(R) provides this software for FREE download over the Internet. You will require Adobe(R) Acrobat(R) Reader version 4.0 or greater to view the PDF files.
