What's the difference between the Slice and Profile commands in Surfer?

The Grids | Calculate | Slice and Map Tools | Add to Map | Profile commands are both ways you can create a topographical profile of your grid. However, there are some differences.

 

Profiles are very quick and easy to create. You simply click on the map to draw the section line and the profile is automatically created. You can fill under the profile object easily. The profile will show lines representing each of the grids in the map. You cannot enter the exact starting/ending points of the section line.

Surfer's profile tool allows you to automatically create cross sections from grid files.

Profiles are used to easily display topographical profiles by interactively
clicking the points on the map to create the section line.

 

The Grid | Calculate | Slice function takes more steps than adding a profile to view the topographical profile line, and more steps to fill under the profile line - but this method provides more section data. This tool can create both a data file and a BLN as output files. The BLN can be used to create a base map, while the DAT file can specify exact XY coordinates as well as the distance along the profile line. Grid Slice can only work on one grid file at a time, whereas the Profile tool can be used on multiple grid files

Surfer's Slice command allows you to create cross sections at specific x,y locations.

Grid | Calculate | Slice may not be as easy, but you can specify the
precise vertices for the section line.
