Profile

A certain type of DTM, such as a topographic surface, can be represented through profiles which describe point elevation (z value) in a line. This action is performed over numeric model data (grid or isoline) in raster format, presenting in a chart the z value equivalent to point that define the trajectory.

It is accessible through: 

1. Input Layer

• Use combobox or to select a layer that will be used to calculate profile.

If the selected layer does not have 3d information in its geometry, in the Quota Column combobox, select the attribute that contains the attribute to be used.

2. Trajectory Options: 

•  Edition:  Allows to draw trajectories. 

Enables the following tools:

  Create trajectory by click on the path.
   Move selected point in the trajectory.
   Add a point on selected trajectory.
   Delete selected point from the trajectory.
    Delete selected trajectory.
    Invert trajectory direction.

• Selection:  Allows to select a layer with the trajectories.

2.2. Use selected geometries: Set the checkbox if you want to use only the selected lines on the screen. Use the  to select lines, shift +  to select more than one line.

3. Graphic Options :

• Title: Insert the graphic tittle.
• Y Axis: Insert the label of graphic y axis.
