Data Description
  Abstract: This dataset was developed to show areas of Nova Scotia where there is a relative high-medium-low risk of encountering karst and naturally occurring sinkholes caused by soluble bedrock. Karst refers to the distinctive terrain that develops over soluble bedrock and includes features such as sinkholes, caves, and springs. Sinkhole development in karst terrain can cause extensive damage to buildings, roads, and other infrastructure. The primary geohazard in karst areas is the sudden catastrophic subsidence of the ground. This may occur due to the collapse of cavities in bedrock that have been created by the dissolution of soluble evaporite rocks (e.g. gypsum, anhydrite, salt) or carbonate rocks (e.g. limestone, dolostone). It may also occur when soil is washed into openings in underlying soluble bedrock, which creates a void in the soil that migrates upwards by progressive collapse. Sinkholes can be a serious geohazard in some areas of the province and, therefore, caution should be exercised in potential karst areas when constructing buildings, roads, or other infrastructure. This dataset was prepared using provincial geology maps, sinkhole occurrence data, lidar data and hydrogeological databases. The sinkhole occurrence data was obtained from geology maps, lidar, municipalities and consultants. The resulting database contains 1057 records of known locations with sinkholes, karst topography, and karst springs. The risk zones are based on several factors, including geology, sinkhole locations and professional judgment. The high-risk zone contains 96% of the sinkholes in the Nova Scotia Sinkhole Database and has densities of greater than 1 sinkhole per 100 km2. This zone includes the Windsor Group, a 500 m buffer zone around the Windsor Group which contains abundant sinkholes, and the George River Metamorphic Suite. The medium-risk zone contains 3.9% of the sinkholes in the Nova Scotia Sinkhole Database and has densities between 0.1 and 1 sinkholes per 100 km2. This zone includes the Horton and Mabou Groups. The low-risk zone contains less than 0.1% of the sinkholes in the Nova Scotia Sinkhole Database. This zone typically does not contain sinkholes or karst topography. However, sinkholes may still occur in this area due to unmapped soluble rocks (i.e. evaporites or carbonates) or where soluble rocks are close to the ground surface but overlain by other rock types or unconsolidated material.
  Purpose: This dataset was developed to show areas of Nova Scotia where there is a relative high-medium-low risk of encountering karst and naturally occurring sinkholes caused by soluble bedrock.

Processing Step Information
 
Processing Step (1 of 6)
  Description: Summer student Haley Leblanc digitized karst/sinkhole information drawn on various map sheets by Gordon Adams. Jeff McKinnon edited the work, and after consulting with Gordon about how he coded some of the sinkholes, addiitional missed sinkholes were added in Fall 2016
  Software and Version: ArcGIS 10.2/ArcGIS 10.2.2
  Date: Spring 2016
  Contact Person: (see Contact Information)
 
Processing Step (2 of 6)
  Description: Jeff McKinnon created a 1st version of the karst risk map by merging Windsor Group, Horton Group, Mabou Group and George River Metamorphic Suite bedrock polygons from bedrock datasets available (both published and not published). Another database was created containing karst/sinkhole point occurrences from datasets that contained this information. This work was completed in Jan. 2017.
  Software and Version: ArcGIS 10.2.2
  Date: Spring 2016-Fall 2016
 
Processing Step (3 of 6)
  Description: After a review of the data, a 500m buffer was added to the areas of high risk for karst in the Windsor Group. Gaps in the province were also filled with recent mapping in the Antigonish Highlands (Chris White) and the Kennetcook area (Fraser Keppie). Additional point data was added to the karst occurrence database from Fred Baechler and the West Hants Municipality.
  Software and Version: ArcGIS 10.2.2
  Date: Winter 2017
 
Processing Step (4 of 6)
  Description: A final copy of the karst risk dataset was created with all layers integrated together. This included: adding low risk areas not covered by the units with high or medium karst risk (from the provincial coastline polygon), adding areas of karst digitized by Garth Demont from LiDAR in the Antigonish area as a separate dataset, adding to the main dataset well data from Gavin Kennedy that contains Windsor Group rock but falls outside the Windsor Group mapping, topological editing of the karst risk areas, and the dissolving of the karst risk areas into separate datasets for high-medium-low risk and karst areas by group (ie. Windsor, Horton, well data, etc)
  Software and Version: ArcGIS 10.2.2
  Date: Fall 2017
 
Processing Step (5 of 6)
  Description: A karst risk online map application was created by Jeff Poole. During this process, it was determined that an additional layer needed to be created for risk areas without the 500m buffer for the Windsor Group. This was created by Jeff McKinnon, with additional topological editing to finalize the layer.
  Software and Version: ArcGIS 10.2.2
  Date: Winter 2018-Spring 2018
 
Processing Step (6 of 6)
  Description: Preparation was completed for the release of the karst risk layers as a digital product by the standardization of the digital dataset tables. This work was completed by Jeff McKinnon.

  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 https://novascotia.ca/natr/meb/pubs/pubs3.asp. Data Formats GMB 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. Fonts A number of NSDEM or GSC fonts may be required to properly view our data sets in an ArcMap project or to view the hard copy maps in a PDF format (normally the fonts will be embedded in the PDF). The fonts required for a particular data set may be found in the c:\nsdem\dp999v9XX\d999YY\arcmap\fonts directory on your computer after you download the data set. A complete set of all of our fonts will be installed in the c:\nsdem\fonts directory which is automatically installed and updated with our digital products. In order to see a complete list of fonts that are used and to download the NR&R and GSC fonts from our web site please go to https://novascotia.ca/natr/meb/download/dpinfo.asp.Any of these fonts can be installed on your computer by using going to Start - Settings - Control Panel - Fonts - File - Install. ArcMap Project Information Our SHP products include an ArcMap 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\arcmap\project directory. 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 GMB'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 web site 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. Geological maps and associated digital products are intended for use at the published scale of the map.
