Answer:
Interpolation Methods. Interpolation is the process of using points with known values or sample points to estimate values at other unknown points. It can be used to predict unknown values for any geographic point data, such as elevation, rainfall, chemical concentrations, noise levels, and so on.♥️#⃣✌#⃣♥️#⃣♥️#⃣

This method is best for gently varying surfaces, such as elevation, water table heights, or pollution concentrations. The Spline method of interpolation estimates unknown values by bending a surface through known values. There are two spline methods: regularized and tension.
