High resolution satellite imagery and GPS collars can help assist in the assessment of patch selection by grazing cattle in semi-arid savannas

摘要：

Introduction The selection of different patch types for grazing by cattle in tropical savannas is well documented.Advances in high resolution satellite imagery and computing power now allow us to identify patch types over an entire paddock,combined with GPS collars as a non intrusive method of capturing positional data,an accurate and comprehensive picture of landscape use by cattle can be quantified.
