Image-based rangeland monitoring at multiple scales

摘要：

Introduction Sustainable rangeland management is enhanced by accurate ecological assessments and these,in turn,can be enhanced by advancing technology and decreasing labor costs.Image-based,multi-scale monitoring can reduce data-collection costs and reveal pattern and process ( Wu,1999) to allow,for example,assessing the relationship between the functional integrity of ecosystems and biodiversity across regions (Ludwig et al.,2004).Here we examine the potential benefits of image-based,multi-scale monitoring protocols.
