Chapter 26 Coming Soon! Spread Model Data Export

Last updated 30 Sept 2024

26.1 What is the Spread Model Data Export?

The Spread Model Data Export summarizes and formats sample data from the CWD Data Warehouse for use in the spatial diffusion tool. The spatial diffusion tool is an independent tool used to identify how CWD naturally spreads across the landscape.

26.2 What Questions Does it Answer?

Question 1. Can I use the CWD Data Warehouse with the Spatial Diffusion Software? The Spread Model Data Export links CWD Warehouse Data with the spatial diffusion tool so that managers using the CWD Data Warehouse do not need to reprocess their surveillance data.

Question 2. What is the Spatial Diffusion Software used for? The spatial diffusion tool is used to understand how CWD naturally spreads across the landscape.

26.3 Output Details

26.3.1 Outputs in the CWD Data Warehouse:

  • The SpatialDiffusion.xlsx file Containing surveillance data, which is necessary for immediate upload into the Spatial Diffusion Software.

  • The SpatialDiffusion.tiff file Containing geo spatial data, which is necessary for immediate upload into the Spatial Diffusion Software**.

26.3.2 Outputs in the Spatial Diffusion Software:

Maps containing information on disease spread through space and time.

26.4 Abbreviated Tutorial

  1. Run the Spread Model Data Export to summarize and format data from the CWD Data Warehouse.
  2. Download the SpatialDiffusion.xlsx and SpatialDiffusion.tiff files from the attachments column of the model execution page of the CWD Data Warehouse.
  3. Use your internet browser to access the external spatial diffusion tool located at xxx.
  4. Upload the SpatialDiffusion.xlsx and SpatialDiffusion.tiff files into the spatial diffusion tool.
  5. Deploy the model setting section of the spatial diffusion tool.

26.5 Parameters Needed to Execute the Model

  • Model type: Select ‘Spread Model Data Export’ from the drop-down list.

  • Reference name: Label the run.

  • (Optional) Applicable season-year: Label the season-year of the run to assist in documentation.

  • (Optional) Notes: Enter any remarks about the run.

  • Season-year: Select the season-year to be used in the estimation.
