Hi, I'm try to create bathymetric contours for a water body but am generating some undesirable features. I know that the bottom slopes away from the shoreline at a consistent angle; however, I keep getting bulbous features between data points. I have tried interpolating with a few different methods (i.e. TINs, IDW, Topo to Raster, and Spline) but keep getting similar results. Below is the output from the Topo to Raster interpolation. I used the point depths (shown in red) and the shoreline as a contour with depth = 0. Is there a better tool or method to refine the bottom surface and make it more closely resemble actual conditions? Any feedback is greatly appreciated! Thanks
