Implement Kriging interpolation to estimate climate values at unobserved locations.
Select Suitable Library: Choose a geostatistical library (e.g., scipy, PyKrige) for Kriging interpolation.
Load and Prepare Data: Load the climate dataset containing observed values of precipitation, temperature, latitude, and longitude.
Spatial Data Exploration: Visualize the spatial distribution of observed data points on a map to understand their geographic spread.
Interpolation Setup: Define the variogram model (e.g., spherical, exponential) and other parameters necessary for Kriging interpolation.
Split Data: Divide the dataset into training and testing sets, reserving a portion for model validation.
Perform Kriging: Apply the chosen library's Kriging function to estimate climate values at unobserved locations based on the observed data.
Model Validation:
Evaluate the accuracy and performance of the Kriging model.
Cross-Validation: Implement cross-validation by comparing the Kriged values to the observed values in the testing set.
Calculate Prediction Errors: Compute error metrics (e.g., Root Mean Squared Error, Mean Absolute Error) to quantify the accuracy of the Kriging predictions.
Generate Validation Plots: Create visualizations (e.g., scatter plots, histograms) comparing predicted and observed values to assess model performance.
Generate Kriged Climate Surfaces:
Create continuous climate surfaces for precipitation and temperature across British Columbia.
Define Grid for Interpolation: Establish a spatial grid covering the entire British Columbia region to generate the continuous surfaces.
Apply Kriging to Grid: Utilize the trained Kriging model to estimate climate values at each point within the grid.
Create Visualizations: Generate maps displaying the Kriged climate surfaces for precipitation and temperature.
Export Results: Save the Kriged climate surfaces as spatial datasets (e.g., raster files) for further analysis and visualization.
