Gradient

Gradient creates a 'slope' Grid from the currently open TIN as gradients between 0 and a value greater than 100%.

100% equals a slope of 45 degrees. Slopes greater than 45 degrees will have a value larger than 100%.

In theory the gradient becomes infinite as the slope nears 90 degrees. In practice the maximum value in Cadcorp SIS Desktop 9.1 is 3276.7%.

Select Analysis > Grids > Slope and Aspect > Gradient.

This opens the grid options:

• Enter the desired cell size (this is in metres)
• Check the tickbox to save this particular grid as a Named Object:
  
• Check the tickbox to include this as a graphical item in the dataset.
