Example Base Elevation contours Sampled locations and values
<strong>INTERPOLATION</strong> 1 st Method - Thiessen Polygon Assigns interpolated value equal to the value found at the nearest sample location Conceptually simplest method Only one point used (nearest) Often called nearest sample or nearest neighbor
