This study incorporated GPS units given to hunters and traditional self-reporting questionnaires with GIS to give game managers a better idea of hunter land-use patterns.  It also explored the differences in GPS recorded hunting tracks and the distances self-reported by the hunters in the traditional questionnaires used to make ungulate management decisions during hunting season.  The authors also were able to link non-spatial data, attitudes about hunting and game management collect3ed via questionnaire, with the spatial data recorded by each GPS unit, through GIS.  This study is an expansion on the paper employing the same techniques on ptarmigan hunters in Norway by Broseth and Pedersen (2000).  The hunter movement data was supplemented with density of hunters data collected during aerial surveys of the study area.  During these surveys technicians were equipped with tablet personal computers and digitizing pens; the computers ran software showing detailed maps of the area from the technicians point of view from the airplane and the digitizing pen was used to plot the location of hunters as they were spotted during each transect of the aerial survey.  This data was used to create hunter-density probabilities for a map of the study site.  This data was then joined using ArcGIS to create detailed datasets linking behavior in the field and hunter characteristics.  My thesis project too seeks to create a dataset of non-spatial attributes linked with locational data, so this paper was helpful in thinking about which characteristics may be most useful in a graphical representation.
