Slope At Points

This command reports and labels the slope percent at user Screen Picked points or Surface Points. Surface Points can work well on grid files, (.GRD), but is typically too much information for triangulated surface files (.TIN or .FLT).

The slope is computed from the surface model file (.TIN, .GRD, or .FLT).

As the crosshairs are moved across the surface, the slope at the current position is displayed in a floating dialog box.

In addition to labeling the slope value at the user specified points, a Leader Arrow can be drawn in either the uphill or downhill direction. The dialog also allows you to specify Label Prefixes and/or Suffixes, Decimal Precision, and Slope Format. The Create Report option creates a report with each point and slope.

The Set Layer/Size/Color By Slope Ranges option invokes the Define Ranges dialog box. Enter slope values in the first column of boxes to set the Ranges.
