Raster Edition

It is only possible to perform raster edition after executing the Connected Components Labeling, which is used to create a vector representation of an IL from dynamic segmentation routines. The raster edition is performed over a raster map so that the boundaries between the raster map themes are well defined.

Editing a thematic image:

  • on the "Control Panel", select the Image IL that contains the Thematic Image and Labeled Image (segmented image corresponding to classes boundaries):
  • click on Execute - Draw or on the active screen to see both images;
  • click on Thematic - Raster Editing... ;
  • click on Thematic Image on the "Control Panel" to activate it, and, on the right, click on CR. The name of the thematic image is presented - this is the image to be edited;
  • click on Labeled Image on the "Control Panel" to activate it, and, on the right, click on CR. The name of the labeled image is presented. This is the image to be used as reference to edit the thematic image;
  • the Classes list presents the classes created for the thematic IL. Select from the list the class that you wish to associate to the polygon. The chosen name will be presented to the text box New, in Change of Classes;
  • click on the polygon on the active screen. Observe that the name of this polygon class is presented at Current, and a green cross (+) marks the polygon selected for modification. If you wish you can select more than one polygon to receive the classes selected ar New;
  • click with the mouse right button on the active screen to begin the changes.
  • click on Execute - Draw or on the active screen to see the modifications. Repeat the two steps above to perform other changes.
