Open an existing map in the NRDS web application.

Click on the gear icon (wheel) at the bottom of the screen.

Select 'Layers' to access the custom layer user interface.

Alternatively, go to 'Map Settings'.

Click on the 'Custom Layers' tab.

Click 'Add Custom Layer' to create a new layer.

If using a template, navigate to the geometry question.

Click on 'Layer Settings'.

Link a default layer or create a new custom layer.

Choose the endpoint type for your layer:

For this example, focus on surveys.

Select 'Point' as the endpoint type.

Choose 'Sample Site Location' as the category option.

Click 'Add Group' to add category options for symbolization.

Select 'Sample Type' to grab options and add them.

Set the zoom label range for when labels appear on the map.

Choose a date filter field if needed.

Select an icon, size, default color, width, opacity, and visibility settings for the layer.

For polygons, customize the inside and outside colors.

Add or remove options as needed.

Create filters to display specific features (e.g., only active traps).

Build filter expressions based on your criteria.

Save the custom layer settings.

Add the new layer to the map.

Set conditions for when labels should appear based on zoom levels.

Review and finalize all custom layer settings.

Ensure the layer displays correctly on the map.

Ensure that the endpoint URLs are valid and accessible.

Double-check filter expressions to avoid errors during setup.

Use predefined templates for quicker setup of common layer types.

Regularly save your progress to avoid losing changes.
