Using the Filters

Using MERMAID Explore Using the Filters

Apply filters using the left-hand panel to refine the data displayed on the map and in the summary metrics. Filtering also determines which data is included when you export.

  • Basic Filters (Countries, Organizations, Projects): Type or select one or more entries from these dropdowns.

  • Advanced Filters: Click Show more filters to access:

    • Date Range: Specify survey start and end dates.

    • Your Data: Check Your Projects Only to view only projects you have access to (requires login).

    • Methods/Data Sharing: Select specific survey methods and their corresponding data sharing levels. 

    • No Data: Include projects that haven’t yet submitted data (useful for project setup checks).

  • Zoom to Filtered Data: After applying filters, click the Zoom to filtered data button (looks like a filter) to adjust the map view to encompass only filtered results.
