ABSTRACT
This chapter focuses on a number of measurement systems applied in practice. They can be classified in six groups: general tourism information system, measurement of day tourists, tourism Satellite Account, tourism and holiday surveys, tourism production index and tourism barometer. A tourism information system (TIS) or destination management information system (DMIS), also called tourism marketing information system (MIS), can be described as a system used to collect, in a permanent and systematic way, the tourism supply and demand data at the destination level necessary for an efficient management and tourism policy. Many destinations have no or only a vague knowledge of the number of day visitors. The day visitors per day can be measured in a very simple way, by reducing the total passengers by the functional traffic. They are an extension of national accounts for selected areas of interest such as tourism.
