Name  Enter the name of the border in the text box.  The Select button can be used to select the name of the border from a variety of attribute names.  Do not use spaces in a border name.

Resampling  As the border is drawn and when drawing of the border is completed, the points in the border are separated by this value.


The border can be either open or closed.  At the conclusion of drawing a closed border, the last point in the border is connected to the first point in the border.


In most cases, borders are drawn on flat maps with the dimension set to 2D.  In rare cases, in may be desirable to draw a border on a 3D surface in which case the 3D Dimension is selected.

Closed Border Paint Assignment

When drawing a closed border, the nodes falling within the closed border can be assigned a paint file identifier.  To perform a paint assignment, check the Assign Paint Identifiers to Nodes Within Border button, select the paint column that is to be assigned, and, if desired, change the name of the column that is to be assigned.  Each node within the border will have its selected paint column assigned the name of the border that is drawn.

It is also possible to change the current assignment of nodes within a border that is drawn.  To do this, set up the desired new assignment as described in the previous paragraph.  Next, select the Reassign Nodes With existing paint column and name.  Any nodes within the border with the reassign column and name will receive the new paint assignment.

Drawing the Border

Once all entries have been made in the dialog, press the apply button.  While holding the left mouse button down, drag the mouse to draw the border.  At the end of the border, release the mouse button then, while holding the shift key down, click the left mouse button to indicate that you are finished drawing the border.  A Caret standard is to draw borders in a clockwise orientation.  If a closed border is being drawn, additional border points will be added to connect the last point in the border to the beginning of the border.  If the border is a closed border any paint assignments, if selected, will be made at this time.

Sometimes is is desirable to have borders with some coincident points, particularly when drawing borders that enclose adjoining regions.  This is performed as follows.  Start drawing a border as usual.  When the mouse cursor is close to the existing border, release the mouse button.  Hold the CTRL key down and click the left mouse button over a point in the existing border where the two borders are to being sharing points.  The mouse cursor will now change to a "+" symbol.  Move the mouse to the point in the existing border where the sharing of border points should cease and, while holding down the CTRL key, click the left mouse button.  The mouse cursor should now change return to an arrow and the border can be continued by drawing in the usual fashion by dragging the mouse with the left mouse button down.
