Objectives

The objective of this course is to teach the students the basic concepts of standard geostatistics. Students will learn, in the course, the main theoretical concepts related to the spatial interpolation of attributes using geostatistics. The students will also work on computer programs to practice the theoretical concepts. The course is developed with theoretical classes, under the professor responsibility, and also with practical laboratories that the student must run out of the theoretical class time. Following the theoretical classes there are some exercises that the student must work on and report the answers to the professor. During the course the students must work, also, in one sample set of interest with the geostatistics concepts and techniques and present to the professor, as well as to the other students, their work results. Finally, the students must write reports about these results.
