Isolines are lines on a map that connect points with equal values of a particular quantity, such as temperature, pressure, or elevation. They help visualize patterns and variations in data across a geographic area.
Think of isolines as contour lines on a topographic map. Just like contour lines connect points with equal elevation, isolines connect points with equal values of another variable to show areas of similarity or difference.
Gradient: Measures how quickly a quantity changes over distance. Steeper gradients indicate rapid changes while gentler gradients indicate slower changes.
Interpolation: Estimating values within known data points using mathematical techniques to fill in missing information.
Extrapolation: Predicting values beyond known data points by extending trends or patterns observed within the given range.
