Contouring of irregular spatial data by hand has been used by geoscientists for many decades. Contouring using a computer is relatively new and has become more widely used in the earth sciences only in the last 20 years. The availability of inexpensive microcomputer hardware and software makes the use of a computer for contouring affordable for nearly everyone. Gridding and contouring software has become flexible enough to satisfy nearly all needs for contouring with speed and convenience. Computer contouring is not perfect, so it is necessary to constantly be on guard and check results for artifacts and make sure the contour results are representative of the data. This course will help build awareness of what to watch for when using each contour method, when a method is most suitable, and when it is not. Since the early 1980's, we have experienced a significant increase in access to computer programs for contouring, as well as a large variety of computer algorithms. Books have been written about the algorithms and how they are used. The purpose of this course is to pull together information on the most commonly used contouring algorithms and reveal the 'secrets' of how and why they are used. These 'secrets' are not really secrets, but to find all this information you have to dig through many books, use the algorithms (hundreds of times) and observe results. We have explored all these resources for you and present the findings in this course. Hand contouring is still done by some people, and the first section of the course covers hand contouring methods, when to use them, and the pitfalls to avoid. Understanding hand contouring is a first step to using contour software effectively. Author Betty L. Gibbs Dr. Stephen A.

About the Course In this introductory course, students explore the full breadth and depth of the mining sector. An array of succinct overviews, video clips, and infographics guide students through a typical mining value chain (exploration, mining, processing, transport, closure, and post-closure). Topics such as artisanal and small-scale mining, project financing, and an overview of a variety of commodities are included. Key trends within mining are also explored including insight into new and developing technologies, and true sustainability within mining. Students will leave this course with a solid grasp of mining terminology, processes, and business practices that will help them work in or with professionals in the mining industry. About the Audience This course provides a robust foundation to the key components of the mining industry and introduces the learner to the mining value chain, industry specific terminology and key concepts. This course is for anyone who is interested in the mining sector and would like a broad overview of the mining value chain without the technical details. Examples of those who may be interested include: geologists, chemists, engineers, government officials, regulators, data scientists, policy setters, non-governmental organizations, procurement specialists, academics, finance professionals, sustainability experts, lawyers, and administrative staff.   Recommended Background This is an introductory level course. No specific pre-requisites are recommended.
