Snap Desktop allows you to show coded questions as clickable images. These are known as Map Controls. To create your own Map Control you must edit your image in the Map Control Editor.

You can convert single and multi-response questions to Map Controls. You must define an area of the image that represents each code, and then set how it will appear when the respondent clicks on it. The image used to form the structure of the map control can be a picture of anything – it is not limited to a cartographical map. Possibilities include:

  • map of a country, region or district split up into areas
  • schematic picture of a human body which may be used to indicate areas affected by injury or disease
  • photograph of a street scene with potentially hazardous situations marked

Map Controls can be associated with single-response and multiple-response questions in electronic editions of the questionnaire, such as, Snap Online, tablet, kiosk or smartphone.

Step 1: Add the question

This section describes adding the single-response Gender question to your questionnaire.

  1. Open your survey in Snap Desktop.
  2. Add a new question. If it is not already a Single choice type question then change it to one and set it as Single response.

Step 4: Save your Map Control to use again

  2. Select File | Save map control and browse for a folder.
  3. Give your Map Control file a name and click Save.

Step 5: Change the Map Control for different screen sizes

Map Controls can take a lot of screen space and take time to load. You can change their size to make them suitable for smaller screens. You can remove them if you are concerned about load time.

  1. Create the Map Control question in your new edition or survey. (Use a Snap Online edition for an adaptive survey, or mobile for one which is only going to be used on mobile devices).
  2. Convert the question to a Map Control (Choose the Show topic and select As Map Control, then click the Show checkbox). If you have added an additional edition to your survey, you will see the gender Map Control. If it is a new survey, you must load your saved Map Control.
  3. Double-click the gray area to open the Map Control Editor.
  4. Select File|Load map control and select the control you saved earlier.
  5. The gender map will load. Select the size control and change the size to 50%. The map will resize.
