SEARCHApp has been designed as a tool that helps to determine a first initial response by emergency services, quickly and easily, specifying the urgency of operational response in cases of missing or missing persons.It requires the use of research techniques prior or simultaneous to the use of this tool, to determine the profile of the subject, meteorological and physical conditions of the ULC area (Last Known Location).This App is based on an assessment table of the factors of an incident proposed by John W. Wade.
