Abstract
A system for providing accurate responses during the administration of a location based question of a computer assisted self interview uses a mouse or other pointing device to allow the user to point and choose a location or proximate area on the map that is responsive to the posed location question. The system allows respondents who are unable to provide accurate street addresses with a means to point at the exact or approximate location that is responsive to the question. For respondents, who because or confidentiality concerns, are unwilling to provide accurate street addresses, it provides a means to point at an area on the map that is responsive to the question with a degree of generality and comfort that they control.
