Use the model

You can use this model in the Detect Objects Using Deep Learning available in the Image Analyst toolbox in ArcGIS Pro. The complete workflow involves postprocessing steps using additional tools.

A simplified workflow is also available with a custom tool packaged as an ArcGIS Pro project template. The sections below describe the steps to use the model with this tool.

  1. Download the Detect Shipwrecks ArcGIS Pro project template to use the Shipwreck Detection pretrained model, or a fine-tuned model as needed.
  2. Start ArcGIS Pro, and from the project selection screen, click Select another project template.
    Select another project template in ArcGIS Pro.
  3. Browse to the downloaded template and click OK.

  4. Provide a name for the new project and click OK.
    Provide a name for the new project.
  5. Ensure that you have added a BAG file in ArcGIS Pro.

    You can download a sample BAG file for Jamaica Bay from the NOAA portal.

  6. Zoom to an area of interest.
    Zoom in to an area of interest in the BAG file.
  7. Browse to <Project_name>.tbx under Toolboxes in the Catalog pane to access the Shipwreck Detection from Bathymetric data tool.

  8. On the Parameters tab, set the variables as follows:
    1. Input Raster—Select the BAG file layer.
    2. Output Detected Shipwrecks—Set the output feature class that will contain the detected shipwrecks.
    3. Model Definition (optional)—Select the Ship Detection (SAR) pre-trained model .dlpk file.
    4. Model Arguments (optional)—Change the values of the arguments if required.
    5. Non Maximum Suppression—Optionally, check the check box to remove the overlapping features with lower confidence.

      If checked, do the following:

      • Set Confidence Score Field.
      • Set Class Value Field (optional).
      • Set Maximum Overlap Ratio (optional).
    6. Processor Type—Select CPU or GPU as needed.

      If GPU is available, it is recommended that you select GPU and set GPU ID to the GPU to be used.

    7. Cell Size—Change if required.

      The expected BAG file resolution is 0.5 meters.

      Note:

      If the model definition is not passed, the model will be automatically downloaded from ArcGIS Living Atlas of the World.
