This thesis provides an integrated approach to common problems with location estimation for animal tracking. Many existing techniques confound problems of location accuracy with simplistic track representations and under-utilization of available data. Traditional techniques such as speed ltering and time spent maps are illustrated with a software package developed by the author with examples of location estimates from southern elephant seals. This software enables the application and exploration of various techniques that have previously not been available in a single solution. These include ltering, temporal gridding, projection transformation and GIS integration. A novel Bayesian approach is introduced for the more general problems faced by dierent tagging techniques. This approach integrates all sources of data including movement models, environmental data and prior knowledge. This general framework is illustrated by application to satellite tag data and light-measuring tag data. Examples are used to ...
