This digital data set consists of 26 color TIFF files, one for each 1:50 000 NTS mapsheet where high resolution aeromagnetic surveys exist over the Meguma Terrane. Each TIFF represents the second vertical derivative of the vertical gradient magnetic data, with most of the original data being collected by aeromagnetic surveys flown by the Geological Survey of Canada (GSC), while a couple of surveys were flown by SeaBright Resources.
Purpose:
To assist in identifying structure and stratigraphy in the Meguma Terrane.

There may be positional accuracy errors in the data that came from the original data collection. The entire risk as to the quality and accuracy of the data is with the user and the user shall use his/her own judgment in making use of the data or drawing conclusions from it.
These images were produced by M. S. (Steve) King under contract to MRB. His work and processing techniques are recorded in an unpublished report submitted to the department: Meguma Magnetics, Canada Nova Scotia Agreement on Mineral Development III, Project No. 80803, Contractor's Report: Processing Techniques.
In January 2006 the data set was renamed from HIRESMAG to M008MGAM and moved from the IMAGE directory on the MRB "S" drive to the MAGNETIC directory. This work was done by Brian Fisher.
In January 2006 the .TIF images were converted from UTM zone 20 NAD27 coordinates to UTM zone 20 NAD83 coordinates. This was done by Angie Ehler running the AML file - Tif27to83.aml. The images were renamed at the same time. The xxxxx.TIF image series were renamed to SDM_025_xxxxx.TIF, where xxxxx stands for the NTS map sheet number. This work was done by Angie Ehler.

Technical Prerequisite:
In order to view our digital files on your computer, you require mapping software (e. g. 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" and "TIFF" files. 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).
TIFF files of the image of Nova Scotia divided into several images based on the NTS 1:50,000
map sheets with each TIFF representing the second vertical derivative of the vertical gradient
magnetic data.
