• Displaying a location based question to the respondent in the computer assisted self interview;
• Processing a response to the location based question;
• For an alphanumeric response to the location based question, geocoding the response and continuing with the next step in the computer assisted self interview, if the geocoding is successful, or redisplaying the location based question if the geocoding is not successful;
• Displaying a map for the respondent to use in responding to the question;
• Redisplaying the map by zooming in and out to provide more or less detail for the map display;
