Advances in Sampling Estimation,surveys cannot be only performed on list frames (farms, households, or other legal bodies), or only on spatially defined frames, but also using a combination of these two types of frames..This chapter discusses these different advanced topics in sampling estimation.

Overview and Brief History, the use of spatial reference frames has become more attractive for defining the sampling design. This approach appears to be suited to the analysis of agricultural data, which are often geographically distributed. In this chapter, we outline some survey examples that make effective use of spatial reference frames.

Setting Up the Frame,onal access to the finite population of interest (Särndal et al. 1992). The sampling frame has significant implications on the cost and the quality of any agricultural or non-agricultural survey..This chapter is devoted to the description of the main strengths and weaknesses of the different statistical frames.

Sampling Designs,ped to minimize the survey cost, while controlling the uncertainty associated with the estimates..Each scheme has advantages and disadvantages, but generally a combination can achieve stable and acceptable results in any field of statistical research..In this chapter, we review the main basic sampling designs.

Spatial Sampling Designs,ay be present. The presence of this spatial effect may be inherent to the phenomenon under investigation, so it is desirable and appropriate that we consider this information in the sampling design..In this chapter we discuss the main spatial sampling designs, also with applications, that have been recently introduced in literature.

Book 2015erformed with the open-source software R, readers will learn about the different phases of spatial data collection. The agricultural data analyzed in this book help policymakers and market stakeholders to monitor the production of agricultural goods and its effects on environment and food safety.

An Introduction to Remotely Sensed Data Analysis,rage of a field, and can be used as a proxy for measuring crop and soil attributes. In this chapter, we discuss some statistical techniques for improving and interpreting the remotely sensed images with particular reference to their use in agriculture.
