What is a valid area?
Setting a valid area adds a boundary limit for geospatial responses, ensuring that respondents only answer a question within a set area.
If a respondent tries to add a response (adding a pin, or a point on their line or polygon) outside the valid area they will be told that it is invalid and have to resubmit.
How to set a valid area
To set a valid map area (or areas) you must have already set up an online survey, created a mapping page, added a question and chosen the mapping component. For more information on how to do those things, read the following posts:
Once you have a mapping component saved, you can add a validation rule.
- Click on the Validation rules link on the mapping component, to open the /validation_rules menu
- Set the valid area by drawing an area or uploading a file (geojson or shapefile)
- To upload a file you need a GeoJSON or Shapefile
- To draw a shape follow the instructions in the guide bubble to add your shape to the map
- You can edit a drawn or uploaded shape by dragging or adding new points
- Update the Key Label to choose what you want the valid area to be called in the map key
- Click Save changes
