Andrew Parnell is
currently undertaking a summer research scholarship for the Search and Rescue
Institute of New Zealand (SARINZ).
Andrew is due to start the Masters of Geographic Information Science
(MGIS) in February of this year.

As part of the summer
scholarship scheme at VUW, this summer I was chosen to complete a project
proposed by SARINZ. Using data from New Zealand from 2003-2012, the project analyses
whether watersheds form an appropriate model for search areas of lost persons
in the New Zealand wilderness.
Lost person statistics include locations of where lost persons were last known to be and where they were found.
Using information about the lost person (such as activity, mental and physical capacity, and age), a
person’s behaviour can be used to narrow down the most likely areas where they
will be found.
I compare the locations
of where the lost person was last known to be and where they were found for
each incident. As a result, each incident is classified as one of the
following; found in the same catchment as the last known location; in a
watershed adjacent to the last known location or; in a watershed further
afield.
The use of statistical
analysis in informing searches for lost persons is increasingly common as data and analysis techniques have improved.
The results of this project will expand existing statistical modeling for lost
person behaviour. If the watershed analysis is effective, it will make future search
operations more efficient, faster and increasing the likelihood of finding lost
persons.
