1. A method for tracking an asset, the method comprising: obtaining a geographical boundary; receiving fix data comprising uncertainty parameters defining an area of uncertainty; determining an over-inclusive area of uncertainty based on at least one of the uncertainty parameters; determining a relationship between the geographical boundary and the area of uncertainty based on the over-inclusive area of uncertainty, wherein the relationship comprises one of possible relationships comprising a relationship in which the area of uncertainty is completely inside the geographical boundary; a relationship in which the area of uncertainty is completely outside the geographical boundary; and an indeterminate relationship; resolving the indeterminate relationship using a first order test to determine whether the area of uncertainty is inside the geographical boundary or outside the geographical boundary; and reporting an event based on a change from a previous determined relationship.
