This tool is used to create a polygon from innermost points depending upon the maximum edge of the selected area of interest.
- This tool can only be used on a point layer.
- A minimum of three points should be selected on the layer to create Concave.
The Concave tool can be selected by navigating the following path:
Tools > Vector Processing > Geometry > Concave
The first section requires you to select required data layers to run the Concave tool.
- Select a Point Layer – Layer on which you will run this tool.
The second section requires you to select the range of data for the operation to be implemented. There are two options available:
- Select By Graphics
- All Data
For more information about these options and how to implement them, see Data Selection Methods.
The output polygon layer is represented by an output layer consisting of all the points from the inner polygon.
You can view the output after storing it. To save the output, you must enter the Output Layer Name and click on Save Data button. The saved output will be added as a new layer in the current map session, where you can apply styling as required. This output layer will also be available in 'My Data' section and can be used in any map session of interest.
