The goal of Geostatistic is to predict the spatial distribution of a property.
In this topic we are going to study two types of Spatial Analysis:
i) Conventional Analysis (Nongeostatistical);
ii) Spatial Continuity Analysis (Geostatistical).
We will also try to understand what are Experimental variograms (Nugget; Range and Sill), Variogram models (basic variogram functions) and Estimation (Kriging).
The video includes an Exercise.
The materials for this topic are a slide presentation, a video with an exercise resolution using geostatistics and two guidebooks.

Gathering data from different sources and with different cadence (sampling frequency) is normal in Precision Agriculture. However, the consolidation of those sources of information in a well structured, homogeneous database in sometimes a difficult task.
In this topic, the principles of a successful data gathering and consolidation process will be explained.

A Decision Support System (DSS) is an interactive, computer-based system that helps users in making decisions. Besides the provision of storing and data retrieval, DSS enhances information access and retrieval functions. Designing a DSS for agriculture enables farmers to make effective decisions for higher yield and lower production costs. Precision agriculture, through the use of remote sensing, geographical information systems, global positioning systems, soil testing, yield monitors and variable rate technology, provide a number of inputs into the DSS. Case studies are presented where the DSS is designed to optimize specific inputs, such as water consumption or pesticide applications by employing precision agriculture through information and communication technology.
