|Title:||GPS tracking for monitoring animal, plant and soil interactions in livestock systems||Contributor(s):||Trotter, Mark (author); Lamb, David (author)||Publication Date:||2008||Handle Link:||https://hdl.handle.net/1959.11/10151||Abstract:||GPS tracking is becoming increasingly common as a research tool for monitoring livestock activity. This paper reports on the development of UNEtracker, a low-cost GPS collar that can be deployed in large numbers for monitoring stock movement. An assessment of positional accuracy of UNEtracker showed a mean error from actual receiver position of 4.14 metres with a standard deviation of 3.04 metres. Results demonstrated 99.9% of points fell within 20 and 97.3% within 10 meters of the known point. The UNEtracker was used to track the movement of four steers over a 14 day period. The tracked steers were shown to have distinct preferences for certain areas within the trial site. A Livestock Hour Index (LHI) is used as a means of quantifying and mapping the impact of livestock activity on the landscape. Integration of LHI data with maps of photosynthetically-active biomass (as derived from satellite imagery), elevation, and even information concerning neighbouring herds, has been demonstrated to provide significant interpretation power to the collected data.||Publication Type:||Conference Publication||Conference Name:||9th International Conference on Precision Agriculture (ICPA), Denver, United States of America, 20th - 23rd July, 2008||Conference Details:||9th International Conference on Precision Agriculture (ICPA), Denver, United States of America, 20th - 23rd July, 2008||Source of Publication:||9th ICPA Proceedings CD||Publisher:||International Society of Precision Agriculture (ISPA)||Place of Publication:||United States of America||Field of Research (FOR):||070104 Agricultural Spatial Analysis and Modelling||HERDC Category Description:||E2 Non-Refereed Scholarly Conference Publication||Statistics to Oct 2018:||Visitors: 269
