The main job of this task is to show nearest records from chosen layers in the selected location. We suggest to set the Number of result rows per layer to 3-10 records, depending on the type of data stored in the layer. On the screen below you can see the result of usingFind Nearest task to find 5 nearest records from the Housing blocks layer.
In the task properties you can configure 2 options:
- If you wish to include layer in the Find Nearest task search – tick the check box,
- Here you can set how many records (per layer) should be fetched. Leave 0 for all records.
Find Nearest task is responsible for preparing results of a query. You have to add additional tasks to the same workflow to correctly display the query results. Please add:
- Clear Result Set (required) – to clear any previously found results from result pane,
- Change Layer Visibility (optional) – you can use this task to make any layer visible while using the Find Nearest task. For more information please visit: Change Layer Visibility
- Fetch all records (required)– from inspection. This task is responsible for fetching the selected result set. It can be later displayed in the Aurora result pane,
- Show result pane(required) – this task is needed to display the results of using the Find Nearest task.
This is how a ready to use basic Find Nearest workflow should look:
