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 Details: | ICPA 2008: 9th International Conference on Precision Agriculture, 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: | Monticello, United States of America | Fields of Research (FoR) 2008: | 070104 Agricultural Spatial Analysis and Modelling | Socio-Economic Objective (SEO) 2008: | 830399 Livestock Raising not elsewhere classified | HERDC Category Description: | E2 Non-Refereed Scholarly Conference Publication |
