Abstract: |
This data set consists of one TIFF and JPEG image of airborne magnetic total field, calculated first vertical derivative and calculated second vertical derivative covering parts of NTS map sheets 21A/03, 21A/04, 21A/05, 21A/06 and 20P/13 in the Davis Lake - East Kemptville area of southern Nova Scotia. The data used to generate these images and maps were supplied by the Geological Survey of Canada - Geophysical Data Centre, 615 Booth St., Ottawa, Ontario, K1A 0E9, and the Radiation Geophysics Division, 601 Booth St., Ottawa, Ontario, K1A 0E8. The original magnetic data was acquired as part of the Davis Lake - East Kemptville survey in 1987. The 24-bit colour images were produced with a 10 m pixel size. Shading was from the southeast at 35° above the horizon. The processing and creation of these images was done by M. S. King under contract to the Nova Scotia Department of Natural Resources (NR&R), Mineral Resources Branch(MRB). For complete details see Open File Report 2006-1 by M. S. King. |

|
Purpose: |
The purpose of this data set was to enhance the level of geological knowledge in the project area. |

Technical Prerequisite: |
In order to view our digital files on your computer, you require mapping software (e.g. ArcGIS, ArcInfo, ArcView, MapInfo, AutoCAD). If you do not have this software, ESRI provides two free Map Viewer called ArcExplorer2 and ArcExplorer4 which you can download over the Internet. ArcExplorer2 works with our "E00", "SHP", "JPG", "SID" and "TIF" files, while ArcExplorer4 worked with our SHP, TIF, JPG and web services. 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. Links for these and other map viewers can be found at the bottom of https://novascotia.ca/natr/meb/download/gis-data-maps.asp.
Data Formats
MRB provides its digital data products in a number of formats. You can find our more information on these format and how to use them at https://novascotia.ca/natr/meb/download/dpformat.asp.
ArcView Project Information
Our SHP products include an ArcView project which have all of the shapefiles symbolized and tables loaded with link and joins already created. This project uses relative paths so it should be drive and path independent. It can be found in the c:\data_set_id\arcview\project directory.
ArcExplorer Project Information
We have also included an ArcExplorer 2 project (.aep) and an ArcExplorer 4 (.axl) project for this data set that can be found in the c:\data_set_id\arcexpl directory. The shapefiles are already loaded and have limited symbolization, any related tables are not loaded. The AEP project uses relative paths and should be no problem using it without any changes. The AXL project includes a string "#DPMEPATH#" which you will need to search for and replace with your drive letter and a colon (ex: c:) in order to make the project work. Please note the if you do not install the data set using the default path you may need to replace other parts of the reference to the path in the AXL.
Hotlinks
In order to use the hotlink feature within ArcView 3.x in you may need to load MRB's Hotlink Anything extension which may be located in the arcview/ext directory along with documentation. You may also need to set the variable MEBGIS_HOME on your system to the location of the data set on your system. The SHP product provides an ArcView project set up with the hotlinks working. Some modifications to the HOTLINK field in the database tables or in the HLFILES may be required to make the hotlink work properly. Knowledge of ArcView and hotlinks may be required to make this work properly.
A feature called hotlinks is used in ArcView to link a feature such as a mineral occurrence or cross section to a single text file, image or website etc. For features that we want to link multiple items or documents to we have developed our own hotlink extension for ArcView 3.x called "Hotlink Anything". The extension and documentation on how to install the extension, and set the required MEBGIS_HOME variable to the location of the data set on your system is included in the x:\nsgov\dig_prod_num\data_set_id\arcview\ext directory (example - c:\nsgov\dp305v1sh\g118a\arcview\ext) assuming that you used our default directories when downloading the data. The SHP product provides an ArcView project set up with the hotlinks working. Some modifications to the HOTLINK field in the database tables or in the HLFILES.TXT file may be required to make the hotlink work properly. Knowledge of ArcView and hotlinks may be required to make the native hotlink utility or our extension work properly
Problems and Limitations
Problems have been reported trying to import ARC E00 files into ArcView on Windows 95 computers. Related tables do not import into ArcView. It is not a problem on UNIX, Windows 3.1 or Windows NT, or Windows 2000 platforms. If you experience this problem you can use our DXF/DBF product which contains the tables in dBase format. dBase files can be imported into ArcView. |
