+<h2>DESCRIPTION</h2>
+
+<p>
+The <b>GCP Manager</b> is a <em><a href="wxGUI.html">wxGUI</a></em>
+extension which allows the user to create, edit, and manage
+Ground Control Points. It is available from the menu
+"File | Manage Ground Control Points".
+
+<p>
+The <b>GCP Manager</b> provides an interactive graphical interface to
+manage and analyze Ground Control Points. A backup copy of the initial
+POINTS file is always maintained and updated only on request (Save GCPs
+to POINTS file). This guarantees that accidential changes are not
+permanent and can be undone by reloading the Ground Control Points.
+
+<p>
+The GCP Manager must be started in the target location, not in the
+source location.
+
+<p>
+The GCP Manager is structured into three panels:
+
+<ul>
+ <li>The topmost panel shows a list of Ground Control Points. Tools to
+ manipulate and analyze GCPs are provided in the toolbar. This panel can
+ be moved out of the GCP manager window by either dragging with the
+ caption or by clicking on the pin button on the right in the caption.
+ This panel can also be placed below the map displays by dragging.
+ <li>The two panels in the lower part are used for map and GCP display,
+ the left pane showing a map from the source location and the right
+ pane showing a reference map from the target location. Numbered Ground
+ Control Points are shown on both map displays.
+</ul>
+
+
+
+<h3>Components of the GCP Manager</h3>

+
+<p>
+<em>Toolbars</em>
+<p>
+Two toolbars are provided with the GCP Manager, one for managing the map
+displays and one for managing the GCP list.
+
+<p>
+<em>List of ground control points</em>
+<p>
+The list of Ground Control Points can be sorted by clicking on a column
+header. Clicking on a cloumn header will sort the GCPs ascending, a
+second click on the same column will sort the GCPs descending. Overall
+RMS error and individual RMS errors of all points are often improved if
+the GCP with the highest RMS error is adjusted. Individual coordinates
+can be edited by double-clicking on a row.
+<p>
+The first column holds a checkbox and displays the point number. A GCP
+is only used for RMS error calculation and georectification if its
+checkbox on the left is checked. Uncheck to deactivate a GCP (mark as
+unused GCP).
+
+<p>
+<em>Two panels for map display</em>
+<p>
+The left panel is used to display a map from the source location, the
+right panel to display a map from the target loaction. Zooming in and
+out is always possible with the mouse wheel and done for each map canvas
+separately.
+<p>
+GCPs are displayed in different colors, depending on whether a GCP has
+a high RMS error, is currently unused or is currently selected. Optionally,
+currently unused GCPs are not shown on the map display.
+
+<p>
+<em>Statusbar</em>
+<p>
+At the bottom of the GCP Manager is a statusbar providing several
+functions. The default is set to <em>Go to GCP No.</em> (see also below).
+Typing a number or using the up/down arrows will center the maps on the
+given GCP, useful with a high zoom.
+

+cursor causes the display to zoom in so that the area defined by the box
+fills the display. The map resolution is not changed. Clicking with the
+zoom-in cursor causes the display to zoom in by 30%, centered on the
+point where the mouse is clicked. Zooming changes the display region
+extents (both size and location of area displayed).</dd>
+
+<dt><img src="icons/grass2/zoom-out.png">
+ <em>Zoom out</em></dt>
+<dd>Interactive zooming with the mouse in the active map canvas (source
+or target). Drawing a box or just a left click with the mouse and zoom-out
+cursor causes the display to zoom out so that the area displayed
+shrinks to fill the area defined by the box. The map resolution is not
+changed. Clicking with the zoom-out cursor causes the display to zoom
+out by 30%, centered on the point where the mouse is clicked. Zooming
+changes the display region extents (both size and location of area
+displayed).</dd>

+
+<h4>GCP Map Display Statusbar</h4>
+
+The GCP map display statusbar is similar to the statusbar in the regular
+GRASS GIS map display with two differences, <em>Go to</em> has been
+replaced with <em>Go to GCP No.</em> and <em>Projection</em> has been
+replaced with <em>RMS error</em>.
+<p>
+If <em>Go to GCP No.</em> is selected, a GCP number can be given in the
+left side of the statusbar and the source and target map canvas will be
+centered on the given GCP. Clicking on the map canvas will update
+coordinates for this GCP.
+<p>
+If <em>RMS error</em> is selected, the overall forward and backward RMS
+error is displayed.
