Slope Map Query tool

The Slope Map query tool calculates the slope value in a specified area. The area is defined by a drawn line or polygon, or by a selection of points, lines or polygons.

The output of the analysis is a point feature layer that graphically represents the slope values at different points in the specified area. Each point in the feature layer is color-coded according to the steepness of the elevation model:

  • Sky blue = Slope value is lower than 6 degrees
  • Blue = Slope value is between 6 - 17 degrees
  • Green = Slope value is between 17 - 31 degrees
  • Yellow = Slope value is between 31 - 38 degrees
  • Orange = Slope value is between 38 - 45 degrees
  • Red = Slope value is greater than 45 degrees

    To use the Slope Map Query tool:

    1.     Select one of the Create as options:

    Layer (Entire)

    Create a feature layer under the application's AppData.

    Layer (Streaming)

    Create a streaming feature layer under the application's AppData.

     

    2.     Enter the following parameters:

    Spacing

    Determines the horizontal and vertical spacing (in meters) between query points in the area for which the slope is being calculated.

    3.     Select one of the following methods of designating the area for which the slope query should be calculated:

    • Follow Line - Query points are created along the drawn line.
    • Fill Area - Query points are created inside the drawn polygon.
    • Selected Group - Query points are created at all points, along all lines, or inside all polygons, in the selected group. Select the required group from the Project Tree, and then click Selected Group.
    • From Clipboard - Query points are created for all clipboard objects. Copy the required objects to the clipboard, and click From Clipboard.
