Data Description |
|
Abstract: |
The Department of Natural Resources and Renewables (NRR) (formerly the Department of Energy and Mines) and Nova Scotia Environment and Climate Change (NSECC) maintains an electronic Well Log Database which contains water well construction and location information for water wells in the Province of Nova Scotia. Information in the database is entered from original paper copies of well logs that are submitted by certified well drillers and well diggers to NSECC. This version of the database was extracted on January 5, 2022 and contains 125,517 well logs constructed between 1940 and 2021, inclusive.
|
|
Purpose: |
The water well information included in the NS Well Logs Database is intended for the purpose of water resource management. The information is not to be used for any other purpose.

Positional Accuracy |
|
Horizontal Accuracy Report: |
There may be positional accuracy errors in the digital data that come from the original data collection. The data set contains data gathered from numerous surveys and the accuracy may vary between these. UTM Coordinates (Northings and Eastings): Northings and eastings are in NAD83, zone 20 metric units. UTM coordinates in the database have been approximated based on the various levels of available georeferencing accuracy. The method used is recorded in the Georef_M field, the source of the data is recorded in the Georef_S field, and the associated accuracy of the UTM is recorded in the Georef_A field.
A further description of the georeferencing method, source and accuracy can be found in the descriptions of the Georef_M, Georef_S and Georef_A fields.

Description: |
The Well Logs Database was first published in an MS Access format in 2003 by Nova Scotia Environment. The creation of the database included data entry of older hard copy logs and conversion of a FoxPro database to MS Access format. The database is updated on an annual basis and can be downloaded from: https://novascotia.ca/nse/water/welldatabase.asp

Processing Step (2 of 11) |
|
Description: |
The Department of Natural Resources (DNR) obtained a copy of the 2007 Well Logs Database for the purpose of assigning UTM coordinates to each well log. The Well Logs DB was first updated with the UTM coordinates of wells previously located in the field by DNR staff (Brian Fisher). For all wells that did not have UTMs generated using GPS equipment (drillers were given GPS units after 2004) the following processing steps were conducted: Where a PID was available in the 'PropertPID' field of the database, the PID centroid was assigned to the well log. The following methods were then used (in order of decreasing georeference accuracy) to generate UTMs for the well logs from grid centroids: NTS claim reference, Nova Scotia Atlas grid reference, Nova Scotia Mapbook grid reference, NTS tract reference. The remaining logs missing UTM coordinates were generated using the community centroid from the NS Gazeteer file. Finally, other existing databases (e.g. pumping test database) were cross-checked with the well logs database, and if a better location estimate was available, the UTM was assigned to the well log (Gavin Kennedy). All units in the database were converted to metric.

Processing Step (7 of 11) |
|
Description: |
Processing steps were repeated as new data became available with each annual MS Access release of the DB. Although a formal DP release of the database was not issued, the interactive map was updated annually to reflect the latest version of the well logs database. Georeferencing of well logs in some areas was improved as part of the project work, using hard copy map locations of wells and civic addresses to generate UTMs (Gavin Kennedy).

Technical Prerequisite: |
In order to view our digital files on your computer, you require mapping software (e.g. ArcMap, QGIS, MapInfo, AutoCAD). Links for these and other map viewers can be found at https://novascotia.ca/natr/meb/download/mapviewers.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 DEM 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 dataset may be found in the c:\nsdnr\dp999v9XX\d999YY\arcmap\fonts directory on your computer after you download the data set. In order to see a complete list of fonts that are used and to download the DEM and GSC fonts from our web site please go to https://novascotia.ca/natr/meb/download/dpexttool.asp. Any of these fonts can be installed on your computer by going to Start - Settings - Control Panel - Fonts - File - Install.
ArcMap Project Information
Our GDB products include an ArcMap project which have all of the GDB feature classes symbolized and tables loaded with links 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
Geological maps and associated digital products are intended for use at the published scale of the map.
