Points are weighed using a given field from its attributes table.  &#10;&#10;Weights are not constant within the search radius, but vary with distance.  A smoothly curved surface is fitted over each point, having the highest value at the point itself (distance = 0) and diminishing with increasing distance from the point, reaching zero at the search radius distance from the point.&#10;" description="Description" type="0">
