Hone your maps by Assigning NoData with Surfer (webinar)

Do you have unneeded or unreliable data after gridding that you don't want in your final product? Fine tune your grid by Assigning NoData in Surfer! Use the Assign NoData tool to model a lake with the ground surface trimmed away. Or, use it to cut out all data over a specified distance from a sampling location. You can even use the Assign NoData tool to replace a portion of a grid with another grid!

This webinar covers how to Assign NoData to XYZ data points, vector contour lines, and a grid file. Download the data and follow along!

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
