Map point, line and area questions

• Map point: Respondent marks a location on the map with a pin. The easiest map question that can be used to ask almost anything related to maps.
• Map line: Respondent draws a line, typically a route, on the map.
• Map area: Respondent draws an area on the map. This works best in surveys where the focus is on a large area. On projects with a smaller geographical scale (e.g. re-design a park), the Map point is often a better option as there won't be as much overlap between the areas that respondents draw.

Add a map question to your survey:

1. Add a background map to the questionnaire page (instructions).

2. Add the map question from the element library.

3. Write the question and the drawbutton text. Respondents click the drawbutton to start drawing on the map. Drawbuttons look like this in the survey:

   

   Adjust the color of the button and add an icon to fit with the visual themes of your survey. You can browse the available icons at Font Awesome.

   

4. Click Create a pop-up to ask respondents further questions about the locations they mark/draw.

   

5. Test in Preview.
