Area intersection tools#

The Area intersection tool allows publishers to perform spatial overlap analyses using data sources available in a MapX project.

The tool supports two types of analysis:

  • Calculate area of intersection: Calculate the area shared by selected data sources, expressed in square kilometres (km²).

  • Create new layer based on the intersection: Generate a new data source containing the intersecting areas.

How do I use the Area intersection tool?#

The tool is available to publishers through the Toolbox. Click Area intersection tools to open the interface.

Analyses are performed at the project level. Only data sources published in the current project can be selected. To limit computational requirements, each analysis is restricted to the geographical extent of a single country.

Area intersection tool interface#

To perform an analysis, follow these steps:

  1. Select the analysis type.

    Choose between Calculate area of intersection and Create new layer based on the intersection.

    Both analyses can be performed separately using the same inputs.

  2. Select the data sources.

    Select up to three data sources from the current project.

    Selection of data sources#

  3. Select a country.

    Choose the country within which the analysis will be performed. Country boundaries come from the GAUL 2015 dataset.

  4. Name the output data source (if applicable).

    If Create new layer based on the intersection is selected, enter a name for the new data source. It will be published in the current project.

  5. Run the analysis.

    Click Run analysis to start processing.

    • Calculate area of intersection: The calculated overlap area (in km²) is displayed directly in the MapX interface.

      Calculate area of intersection#

    • Create new layer based on the intersection: Once processing is complete, you will receive an email confirming that the new data source is available. You can then use it to create views in the current project.

Note

The Area intersection tool is available only to publishers because spatial analyses require significant computing resources.

Each analysis supports a maximum of three data sources, in addition to the selected country’s administrative boundary.
