+<h2>DESCRIPTION</h2>
|
|
|
+
|
|
|
+<em>Interactive Scatter Plot Tool</em> allows to analyze group of raster maps.
|
|
|
+ The tool is integrated into <em><a href="wxGUI.iclass.html">
|
|
|
+ Supervised Classification Tool (wx.iclass) </a></em> (see the screen shot bellow).
|
|
|
+ Also it is possible to launch it from Map Display Window
|
|
|
+ (Analyze map → Interactive Scatter Plot Tool).
|
|
|
+
|
|
|
+The main idea of the tool is that everything is linked together
|
|
|
+(scatter plots together and mapwindow with the scatter plots).
|
|
|
+
|
|
|
+The main feature of the tool is the interactivity, which allows user to:
|
|
|
+<ul>
|
|
|
+ <li> work with multiple plots, which represents multiple raster bands combinations.
|
|
|
+ </li>
|
|
|
+ <li> highlight plotted points in open scatter plots according to currently
|
|
|
+ chosen pixels for classes by it's training areas (supported only in wx.iclass)
|
|
|
+ </li>
|
|
|
+ <li> be able to define areas in plots and the tool will highlight pixels in
|
|
|
+ map display window and corresponding points in other plots
|
|
|
+ </li>
|
|
|
+ <li> plot of confidence ellipses
|
|
|
+ </li>
|
|
|
+</ul>

|
|
|
+
|
|
|
+If editing mode is activated (the green polygon tool in toolbar), the areas which were selected
|
|
|
+in the scatter plots are highlighted. In the image you can see this area for scatter plot of bands B_6 B_7 inside the ellipse.
|
|
|
+Opacity and color of the selected area can be set in settings. The area corresponds to the active class (in this case clouds).
|
|
|
+Selected areas are subset of areas, which belongs to the category.
|
|
|
+<p>
|
|
|
+In the editing mode it is possible to select certain area by the polygon, which can be created and edited by tools in editing toolbar.
|
|
|
+After the area is selected, we can include or exclude it into active category by clicking on the first (plus) respectively
|
|
|
+second (minus) tool in the editing toolbar. In mapwindow corresponding pixels are shown by the class raster representing
|
|
|
+selected areas in scatter plots. In this case we can see clouds class raster (blue), forest class raster (green) and
|
|
|
+water class raster (red).

|
+<h2>NOTES</h2>
|
|
|
+
|
|
|
+The tool can analyze only integer (CELL) rasters.
|
|
|
+
|
|
|
+It works with 8 bit range smoothly.
|
|
|
+The tool is capable of processing data up to 12 bit range, however it is not recommended open many scatter plots in 12/11 bit mode.
|
|
|
+It could require significant amount of memory and plot rendering time can be longer.
|
|
|
+Analyzing of raster data with higher range is not recommended.
|
|
|
+The raster range can be lowered using <em><a href="r.rescale.html">r.rescale</a></em>.

+<h2>KNOWN ISSUES</h2>
|
|
|
+
|
|
|
+Selection of areas in mapwindow is currently supported only if the tool was launched from
|
|
|
+<em><a href="wxGUI.iclass.html">Supervised Classification Tool (wx.iclass) </a></em>
