I am trying to generate bathymetric contours in a pond. I have a polygon feature class which delineates the existing shoreline at a set water height, and I have a point feature class which represent pond depths at different points throughout the pond. The data was collected with a sonar bobber, and so these depth points are not equally spaced from one another.
I have been able to generate rasters using several different tools, including Kriging, Topo to Raster, and Point to Raster. Then I have used the Contour tool to generate contours from these rasters.
The problem is that the rasters, and subsequently the contours that are generated are not strictly accounting for the shoreline boundary. I end up with bathymetric contours that are converging with the shoreline, instead of running parallel to it. I have tried generating points along the shoreline at zero depth, and I am still having issues even with this.
Can do a series of processes or options within a tool that will allow me to specify the shoreline polygon/line as a contour in and of itself? Is there another way to do this?
Thank you in advance for any help.
