Gradient Calculation and Contour Mapping

The video tutorial explains how to calculate the gradient using a specific formula found on the reference table. It emphasizes the importance of understanding and applying the formula rather than memorizing it. The tutorial provides a detailed example, demonstrating how to determine the change in field value and distance using isolines and a map scale. The final result is expressed in units of particles per centimeters cubed per kilometer. The video concludes by encouraging further practice and highlights the relevance of this calculation in contour mapping and isoline examples.
