I have been given a set of depth points for a lake that were taken along the shoreline and along linear transects. What is the best way to use these points to interpolate/extrapolate bathymetric contours for the entire lake? Previous attempts result in contours that are "pinched" around the transect points and don't appear to be interpolated fully for an accurate depiction of depth in the lake (see images below). Thanks kindly for any time or insight you can lend!
