# Blue Locate Tool – Layout Models

The Blue Locate tool also gives you the option of creating a region-based model, where you can instruct the tool to search specific areas of the image for specified features. The layout model can be used to do the following:

- Check for the presence of a feature within one or more regions.
- Verify that the correct feature is in the region, along with the number of instances of that feature within the region.
- Provide a Region of Interest (ROI) for a downstream tool.
