Surfaces Tab
The Surfaces tab is shown only if the job contains a digital terrain
model. The Surfaces tab displays a table that can contain the
following informational columns:
• Icon
– an symbol associated with the surface. For details, see a
list of symbols in the Surfaces Tab
.
• Name
– the name of the surface. To edit the name, click on the
highlighted field and enter a new name. The surface name is
unique and the field cannot be empty.
• Focus point
- the name of a focus point. If the column is empty,
the triangulation is completed in relation to the ground plane. If
set to some existing point, the triangulation will be done with
respect to that point, as if the surface is viewed from that point.
You can select a point from the list of the job's points.
• Layer
– the name of the Layer in which the surface resides. The
Layer sets the plotting style for the surface. Every surface needs a
Layer. In this field, you can select any Layer from the list of user-
created layers.
• Number of Points
– the quantity of points in the surface,
including intersecting points of lines forming this model. You
cannot edit this parameter.
• Number of Triangles
– the quantity of triangles created on the
surface. You cannot edit this parameter.
• Area
– the sum of areas of the triangle projections on the
horizontal plane (if the triangulation is done with respect to the
ground plane) and the vertical plane (if the triangulation is done
with respect to a vertical plane from a focus point for the given
surface). You cannot edit this parameter.
• Minimum Northing
- the minimum value of northing
coordinates of points included in the surface. You cannot edit this
parameter.
