Abstract:
|
GeoFrame is an innovative use of digital photography and GPS technology that reduces the cost of field enumeration to make construction of household sampling frames more affordable. GeoFrame's utility can be extended to other situations where sampling frames may be difficult or too costly to create, such as creating probability samples to evaluate disaster recovery efforts or conduct surveys in developing nations. This paper describes the initial application of this technology to construct a sampling frame for a survey of a difficult to reach population by traditional means. It also presents the results of a field study conducted by RTI International that compares and contrasts the cost and coverage of the GeoFrame methodology versus traditional field enumeration.
