Claim Text:
1. A probabilistic geolocation method, the method comprising: acquiring spatially associated data from an obtained sample of interest; enumerating all possible travel routes the sample of interest may have passed through based on the spatially associated data; inputting said enumerated possible travel routes into a computer processor; determining, by said processor, the frequency with which each possible geographic location appears in the travel routes; and outputting, by said processor, a probability for said each possible geographic location, wherein the outputted probability is conditional upon all travel routes being legal; and applying the following modification to the probability for each possible location: where P(x) is the probability that the sample of interest passes through a given geographic location X, n t is the total number of possible legal travel routes for the sample of interest, n x is the number of legal travel routes including location X, k is the travel route's cardinality, and w(k) is the assigned weight for cardinality k from the user-defined weighting function.
