Do you have unneeded or unreliable data after gridding that you don't want included in your final map presentation? With Surfer you can easily refine your grids and data points to represent the exact data parameters you need. Use the Assign NoData tool to model a lake or pond without the surrounding terrain. Or, use it to remove all the data a specified distance from a outlier sampling location. You can even use the Assign NoData tool to replace a portion of a grid with another grid!

This webinar will cover several ways you can Assign NoData to XYZ data points, vector contour lines, and a grid file. Providing you with the knowledge to choose the method that works best for your personal workflows.

The topics will specifically cover how to:

Assign NoData in the Grid Data dialog using a polygon boundary
Assign NoData using a Mixed NoData flag (Assigning NoData inside and outside multiple polygons)
Assign NoData in the Grid Data dialog using a convex hull
Assign NoData in the Grid Data dialog using an Alpha shape
Assign Nodata on an existing grid and replace a portion of a grid with another grid
