Introduction: Hemophilia is an inherited bleeding disorder caused by deficiencies of clotting factors VIII and IX, respectively. Cartilage degeneration contributes to most of the disease morbidity.

This paper introduces latency mapping as a technique for visualising surveillance coverage. Built on a concept for modelling the total effort by a surveillance force, latency mapping provides an understanding of the collective sensor coverage against a region of interest, in space and time. Latency mapping has been used to support the analysis of maritime surveillance operations in Australia’s ...
