SMS:Contour Labels

The Contour Label Opts command in the Data menu is used to access the Contour Labels Options dialog which can be used to set the label color, font, spacing, size, etc. The dialog may also be invoked through the Contour Options dialog.

Labels can be added to contours one of two ways:

1. The upper left portion of the Contour Label Options dialog controls the generation of automatically spaced contour labels. The user can toggle the generation of automatic contour labels on or off. If the toggle is on, the user also specifies which contours should be labeled and the distance along the contour between labels.
2. In some modules, contour or function labels can be added manually to an image by selecting the Contour Labels tool in the Tool Palette and clicking on the mesh or grid where a label is desired. If the Place on contours option in the upper right portion of the Contour Label Options dialog is selected, the label is moved to the closest contour and the contour is labeled there. If the Place under cursor option is selected, the label shows the value of the point at the click location and is placed there. This option is useful to post data set value labels in regions where there are no contours. Contour labels can be deleted by holding down the SHIFT key while clicking on a label.

The bottom portion of the Contour Label Options dialog control how the labels appear. On the left side, the user can control how many digits of accuracy are desired. The default will match the contour legend. On the right side, the user can select a color and font for the label. For labels on contours, the user may also specify that the contour be oriented to lie along the contour.
