This tool is implemented to create a block output layer consisting of different sections formed by dividing a point layer into several regions using a set of input points. Each section in the block is referred to as a Voronoi cell. This tool can be used to determine the shortest distance to a landmark by identifying the Voronoi cell or section it is nearest to.
The Voronoi tool can be selected by navigating the following path:
Tools > Vector Processing > Spatial Analysis > Voronoi
The first section requires you to select required data layers to run the Voronoi 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 three options available:
- Select By Data Queries
- Select By Graphics
- All Data
For more information about these options and how to implement them, see Data Selection Methods.
The output is displayed on the layer in a polygon. Data enclosed in the output layer is also presented in a tabular form.
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.
