Data_Quality_Information :

  Attribute_Accuracy :

    Attribute_Accuracy_Report : The temperature grid for the base of the Granite Wash was generated using temperature records extracted from the 3D temperature model created by Brinsky et al. (2021). After extracting the predicted temperate data for the base of the Granite Wash, an empirical Bayesian kriging (EBK) interpolation using the “Geostatistical Wizard” tool in ArcPro was performed.

For the EBK interpolation, a total of 399,851 data points were used as input into the model. Listed below are the EBK interpolation parameters employed for this dataset:

Output type: Prediction

Transformation type: None

Semi-variogram model type: Power

Subset size: 100

Overlap factor: 1

Number of simulations: 100

Searching neighbourhood: Standard circular (neighbours included = 15, included at least = 10, sector type = four, and radius = 1,318)

The cross-validation results of the EBK interpolation are as follows:

Mean error: 0.00001535°C

Root mean square error: 0.167088

Mean standardized error: 0.0000859432

Root mean square standardized error: 0.771663°C

Average standard error: 0.2102031

  Logical_Consistency_Report : Grid-cell values represent the temperature at the base of Granite Wash in degree Celsius. Grid-cell spacing is 250 metres by 250 metres.

  Completeness_Report : The final temperature grid covers the extent of the Granite Wash in Alberta.

    Process_Step :

   Process_Description : The process steps to create the temperature grid for the Granite Wash are provided below.

1. Create a fishnet of constant interval; for this task, a 500m-by-500m grid was employed. This step aims to generate a layer for sampling the depth to the base of the Granite Wash and temperature values from their respective source grids.

2. Using the fishnet sample points in step 1, extract the depth to the base of the Granite Wash from the respective source grid. This step was performed using the “Extract Multiple Values to Point” geoprocessing tool in ArcPro.

3. With the updated fishnet sample points containing the depth to base values (step 2), the modelled temperature values from the 3D province-wide model were extracted and saved as a new field in the fishnet sample points GIS attribute table (named Predicted). This workflow was done using the “GA Layer to Points” geoprocessing tool in ArcPro.

4. Using the extracted temperate data saved in the “Predicted” field generated in step 3, perform an Empirical Bayesian Kriging (EBK) interpolation using the “Geostatistical Wizard” tool in ArcPro.

5. After running the EBK interpolation, a geostatistical layer is generated. The next step is to save the generated geostatistical layer as a gridded dataset. For this project, the geostatistical layer was exported and saved as a GeoTiff.
