Ground-truths or Ground-lies? : environmental sampling for remote sensing application exemplified by vegetation cover data

Brogaard, Sara LU and Olafsdottir, Rannveig LU (1997) In Lund electronic reports in physical geography 1.
Abstract
During time of fast development of computer and sensor technology, ground data sampling

strategies have achieved diminished attention in many remote sensing studies. This paper

discusses the importance of designing an appropriate sampling scheme of ground data collection

for remote sensing applications. The difficulties of achieving a balance between the size and the

error of the samples are identified. Different techniques of vegetation cover estimations are

evaluated to illustrate parts of the proposed sampling design. The study indicates that traditional methods of ground data collection for remote sensing applications do not have to result in "ground lies". Determination of a reliable and... (More)
