- Description:
      Abstract: This grid represents the hydraulic head distribution in the Wabiskaw hydrostratigraphic unit (HSU). It is a result of a geostatistical model which was constructed using publicly available data from the following sources:1.Pressure data from drillstem tests from oil and gas wells2.Water-level data from monitoring wells compiled from environmental impact assessmentsThe hydraulic head distribution was mapped at a regional scale using many years of data, thus providing a general indication of regional groundwater flow within the unit rather than site-specific values.
      Purpose: To provide a regional hydraulic head surface for the Wabiskaw HSU

- Data_Quality_Information:
- Attribute_Accuracy:
    Attribute_Accuracy_Report: The following statistics describes the accuracy of the geostatistical layer used to create the final grid:Mean error = -0.38 mRoot mean square error = 16.3 mMean standardized error = -0.005 mRoot mean square standardized = 0.952Average standard error - 17.1 mThe root mean square error of the final smoothed grid is 7.6 m.
  Logical_Consistency_Report: Grid cell spacing is 500 m by 500 m. Grid cells with no data are assigned the value -9999.
  Completeness_Report: The final hydraulic head grid covers the extent of the Wabiskaw HSU as modelled in the Geological Framework of Alberta, Version 3. In addition, the final grid was clipped to the spatial extent of data.
- Positional_Accuracy:
- Horizontal_Positional_Accuracy:
   Horizontal_Positional_Accuracy_Report: See AGS DIG 2024-0006 (data points) for details on the horizontal accuracy of the input hydraulic head point data, which is affected by the locational accuracy of the wells.The grid was smoothed using focal statistics which calculates for each input cell location a statistic of the values within a specified neighbourhood around it, in this case a 3 cell by 3 cell rectangle. Smoothing the surface used the average cell value.
- Vertical_Positional_Accuracy:
   Vertical_Positional_Accuracy_Report: See AGS DIG 2024-0006 (data points) for details on the vertical accuracy of the input hydraulic head point data, which is affected by the locational accuracy of the wells.

Smoothing the surface used the average cell value.Step 3 (Grid Alterations): The final grid was clipped based on the extent of the Wabiskaw HSU, and the spatial distribution of data.
