The toolbar of the sample set editor largely resembles the toolbar of a normal map window; there are extra buttons to open feature spaces, to obtain a legend of the classes of training pixels and to exit the editor.
When you leave the mouse pointer for a short period of time on top of a button, a tooltip will appear with the name of the button / the menu command that it will perform. Also the status bar at the bottom of the window may provide you with a short explanation on the effect of using the button.
The following actions can be performed:
|
Entire Map: |
Displays the entire map in the map window. |
|
Zoom In: |
Zooms in on a selected spot or area in the map. The mouse pointer changes into a magnifying-glass. Click to zoom in on a spot of interest, or drag the pointer from one corner of interest to another (the mouse pointer changes into a little box). |
|
Zoom Out: |
Zooms out directly from the center of the displayed map with a factor 2. |
|
Redraw: |
Redraws the contents of the map window. |
|
Feature Space: |
Opens the Feature Space dialog box to display a new feature space. A feature space visually shows the separation of classes of sampled pixels. You can open as many feature spaces as you like. |
|
Legend: |
Shows a legend of the classes of sampled training pixels in a secondary window. |
|
Exit editor: |
Leaves the editor and keeps all changes. |
The toolbar can be hidden or shown with the Toolbar command on the Options menu. If the action of a certain button cannot be performed at a certain moment, the button appears gray.
