-<h2>DESCRIPTION</h2>
-
-<em>i.points</em> is an
-<a href="imagery.html">imagery</a> function that enables
-the user to mark points on a (raster) image to be rectified
-and then input the geographic coordinates of each point for
-calculation of a coordinate transformation matrix.
-<em>i.points</em> must be followed by use of the GRASS
-program <em><a href="i.rectify.html">i.rectify</a></em>, which
-rectifies the image using the transformation matrix
-coefficients calculated by <em>i.points</em>.
-
-<p>
-<em>Rectification</em> is the mapping (transformation) of
-an image from one coordinate system to another.  The
-geometry of an image extracted into a GRASS LOCATION having
-an x,y coordinate system is not planimetric.  To create a
-planimetric image, that is, to convert the x,y coordinate
-system into a standard coordinate system (for example, the
-UTM coordinate system or the State Plane coordinate
-system), points from a map having the standard coordinates
-must be associated with the same points on the image to be
-rectified.  <em>i.points</em> enables the user to mark
-points on an image and input the standard coordinates for
-that point.  <em>i.points</em> then calculates a least
-squares regression using the two coordinate systems (x,y
-and standard) for the marked points.  A matrix containing
-transformation coefficients is the output file for
-<em>i.points</em>.
-
-<p>During the process of marking points and entering map
-coordinates, the user can compute the RMS (root mean
-square) error for each point entered.  <em>i.points</em>
-does this by calculating the transformation equation (the
-same one that is calculated in the GRASS program <em>
-<a href="i.rectify.html">i.rectify</a></em>), and then
-plugging these results into an equation for RMS error.
-
-<p><em>i.points</em> offers a zoom option to locate precisely
-the point to be marked on an image.  This program also
-offers the user the option of acquiring standard
-coordinates for a marked point from a map layer in the
-target data base.
-
-<p><em><a href="i.target.html">i.target</a></em> must be
-run before running <em>i.points</em> to enable the PLOT
-RASTER option to be used and to identify a target data base
-LOCATION_NAME and MAPSET for the rectified image.  To run
-<em>i.points</em>, a graphics monitor is required.
-
-<p>The procedure for marking points, entering coordinates, and
-calculating RMS error is described below.
-
-<p>The first prompt in the program asks the user for the 
-<a href="i.group.html">imagery group</a> to be
-registered.  Note that if 
-<em><a href="i.target.html">i.target</a></em> is not run
-before <em>i.points</em>, the <em>i.points</em> program
-will display the following error message:
-
-<pre>
-ERROR: Target information for group [spot] missing
-       Please run i.target for group [spot]
-</pre>
-
-After entering the group to be registered the terminal screen
-displays the message: 
-
-<pre>
-      Use mouse now...

-
-The graphics monitor displays the following screen:

-</pre>
-
-The user then enters the easting and northing (separated by
-a space) for the point marked on the image.  If the user
-wishes not to enter a coordinate, he or she may simply hit
-RETURN to return control to the mouse;  the marked point
-then disappears.
-
-<h3>PLOT RASTER</h3>
-
-In addition to acquiring reference points from a standard
-map, the user has the option of acquiring the reference
-points from a raster map layer in the target data base
-LOCATION_NAME.  The data base raster map layer is displayed
-by placing the mouse cross hairs on the words PLOT RASTER.
-The following line is then displayed at the bottom of the
-graphics monitor:
-
-
-<pre>
-       ________________________________________________
-      | Cancel|  Indicate which side should be plotted|
-      |_______|_______________________________________|
-</pre>
-
-Which side of the graphics monitor is to be plotted
-is indicated by placing the mouse cross hairs on the 
-half of the graphics monitor screen that the user would like to use,
-and pressing the left mouse button.  The following pop-down
-menu will be superimposed on the half of the screen that was chosen:
-
-
-<pre>
-    _________________________________________
-   | Double click on raster (cell) map layer|
-   |              to be plotted             |

-</pre>
-
-After the raster map layer is displayed the following message appears
-at the bottom of the graphics monitor:
-
-
-<pre>
-     ______________________________________
-     | input method --&gt;|  keyboard|  screen|
-     |_________________|__________|________|
-</pre>
-
-If the user wishes to use the plotted raster map layer only
-as a comparative reference, then the keyboard can be chosen
-as the means to input coordinates corresponding to the
-marked points on the image.  This is done by placing the
-mouse cross hairs on the word KEYBOARD and pressing the
-left button on the mouse.
-
-
-<p>
-If the user selects the SCREEN option, then points marked
-on the image will automatically be associated with the
-coordinates from the corresponding points on the target
-data base map layer.  In this option, when the user marks a
-point on the image, the following menu is displayed at the
-terminal:
-
-
-<pre>
-___________________________________________________________
-| Point 5 marked on the image at|                          |

-|                               |                          |
-| Point located at              |                          |
-| East: 679132.57               |                          |
-| North: 4351080.67             |                          |
-|                               |                          |
-|                               |                          |

-|                               |                          |
-|__________________________________________________________|
-| use mouse now...                                         |
-|__________________________________________________________|
-</pre>
-
-
-The user then uses the mouse to mark a corresponding point
-on the displayed image from the target data base.  The
-coordinates for the target data base map layer are
-automatically saved as the coordinates corresponding to the
-marked point on the image.
-
-<h3>ANALYZE</h3>
-
-After a number of points have been marked (4 to 7), the
-user can check the RMS error of the points marked on the
-image.  This is done by placing the mouse cross hairs on
-the word ANALYZE at the bottom of the graphics monitor.  An
-error report resembling that shown below is superimposed on
-the graphics monitor:
-
-
-<pre>
-______________________________________________________________________
-|         error                 image                 target         |
-|#     row     col    target    east    north      east       north  |
-|____________________________________________________________________|
-|1     0.0     -0.9    1.0     1048.5   -144.8   679132.5   4351080.6|
-|2     0.4     1.0     1.3     2153.1   -567.2   684314.7   4399001.4|
-|3    -1.2     -0.5     .6     1452.8   -476.5   567841.4   3457682.8|
-|4     1.1     0.5     1.3     1034.0   -109.2   677573.8   4352626.4|
-|5    -2.7     14.0    14.2    1048.6   -144.9   679132.6   4351080.7|
-|                                                                    |
-|____________________________________________________________________|
-|    overall   rms    error:   4.46                                  |
-|____________________________________________________________________|
-</pre>
- 
-The following menu then appears at the bottom of the graphics monitor:
-
-<pre>
- ____________________________________________________________________
-| DONE|  PRINT FILE|   Double click on point to be included/excluded|
-|_____|____________|________________________________________________|
-</pre>
-
-The RMS error for the image is given under the column
-TITLEd "error" and subTITLEd "row" and "col".  In the above
-report, point number 1 is 0.0 rows and -0.9 columns from
-the predicted location calculated from the transformation
-equation.  The RMS error for the target raster map layer is
-listed under the heading "target".  This is the RMS error
-for the east and north coordinates of the target map layer,
-but it is presented in the table using one general value.
-The overall RMS error is displayed at the bottom of the
-screen in meters.  Points that create high RMS error are
-displayed in red on the graphics monitor (represented here
-in italics).
-
-<p>The location of the point marked on the 
-<a href="i.group.html">imagery group</a> file is given
-under the heading "image" and the subheadings "east" and
-"north".  The location of the point in the target data base
-is given under the heading "target" and the subheadings
-"east" and "north".  If the user would like to exclude or
-include a point, this can be accomplished by placing the
-mouse cross hairs on the point number to be included (if
-the point is absent) or excluded (if the point is
-displayed) and pressing the left button on the mouse
-twice.  When a point is excluded, it is not afterwards
-included in the calculation of the RMS error, or included
-in the final transformation matrix.  However, it can be
-retrieved within <em>i.points</em> at any time by double
-clicking with the mouse as described above.
-
-<h3>QUIT</h3>
-
-To end the <em>i.points</em> program place the mouse cross
-hairs on the word QUIT;  the marked points (including
-coordinates) will be saved.
-
-
-<h2>NOTES</h2>
-
-A good rule of thumb is to mark at least 12 to 15 points
-which are evenly distributed over the entire 
-<a href="i.group.html">imagery group</a> file in order to
-obtain an accurate transformation equation for the
-rectification process.  The RMS error may increase with
-more points added, but the transformation equation will be
-more accurate.
-
-<p>An RMS error of less than or equal to approximately one
-resolution unit (pixel or cell) for the image being
-rectified is generally considered acceptable.
-
-<p>In order to use a digitizer with <em>i.points</em>, at
-least one digitizer driver besides "none" (the on-screen
-digitizer) must be available in the digitcap file.
-
-<p>This program is interactive.

- * PURPOSE:      enables user to mark points on (raster) image to be rectified,
- *               and then input the geographic coordinates of each point for
- *               calculation of a coordinate transformation matrix

-<h2>DESCRIPTION</h2>
-
-This program enables the user to identify coordinate pairs of points from a
-vector map or keyboard entry and corresponding points in an image to be
-rectified. The map coordinate values of each point are used to calculate a
-transformation matrix.  The operator may then use the 
-<em><a href="i.rectify.html">i.rectify</a></em> program to rectify the image using
-the transformation matrix coefficients calculated from the control point
-file created in <em>i.vpoints</em>.  The
-<em> <a href="i.rectify.html">i.rectify</a></em> program performs a first, second or
-third order transformation of the image.
-
-<p>The first step is to display the unrectified image and
-corresponding vector map data.  The operator would then
-mark corresponding control point locations on the image and
-map. To identify the precise location of a point to be
-marked, <em>i.vpoints</em> has a zoom option.  In addition to
-marking control points on an image to be rectified and
-inputting their world coordinate values using the
-keyboard,  <em>i.vpoints</em> has the option to simultaneously
-display vector map data available in the targeted database,
-and identify on the vector map the location of the
-corresponding marked points.  When this option is chosen,
-the coordinate values are input automatically.  Any GRASS
-map layer or vector map in the targeted database LOCATION
-can be displayed using <em>i.vpoints</em>.  The <em>i.vpoints</em> program
-also has the capability of overlaying (i.e., warping) the
-vector data onto the raster image to visually check the
-accuracy of the registration based on the current set of
-active control points.  During the process of marking
-points and entering map coordinates, the user can compute
-the RMS (root mean square) error for each point entered.
-The <em>i.vpoints</em>  program does this by calculating a
-transformation equation (the same one that is calculated in
-the GRASS program
-
-<a href="i.rectify.html">i.rectify</a>
-2).  Coefficients are
-computed for the equation.  The coefficients are then used in the
-equation along with the x,y coordinates of the marked points.  The
-results are plugged into an equation for RMS error.  The
-interpretation of RMS error is described in the ANALYZE subsection.
-
-
-<p>The procedures for marking control points (registration
-points), displaying vector map layers,  overlaying vector maps onto
-the raster image, and calculating RMS error are described in the
-following sections .
-
-
-<p>To enter the program (the <em>i.vpoints</em> program requires the use of a
-graphics monitor) type <em>i.vpoints</em>:
-
-
-<dl>
-     <dd><b>i.vpoints</b>
-</dl>
-
-The first prompt in the program asks for the imagery group to
-be registered . . .
-
-
-<pre>
-     Enter imagery group to be registered
-     Enter 'list' for a list of existing imagery groups
-     Enter 'list -f' for a verbose listing
-     Hit RETURN to cancel request
-     &gt;
-</pre>
-
-For example,   
-
-<dl>
-<dd>&gt;<b>list</b>     
-</dl>
-
-might produce the following response:
-
-<pre>
-     &lt;list&gt;

-     test
-     - - - - - - - - - - - - - - - - - - - - - - - - - -
-     hit RETURN to continue --&gt;
-</pre>
-whereas,  
-<dl>
-<dd>&gt;<b>list -f</b>

-The imagery group entered above should contain the files
-that you wish to rectify.  After entering the group to be
-registered, the terminal screen displays the message:
-<pre>
-     &gt;test
-     &lt;test&gt;
-     Use mouse now . . .
-</pre>
-And the color graphics monitor displays the following
-screen:
-
-<p>     Any single file in the imagery group may be used to mark
-points, and points can be marked on more than one file in the
-imagery group to accumulate the suggested minimum number of points
-(3 for a 1st order transformation, 6 for a 2nd order, and 10 for a
-3rd order).  Any file in the imagery group can be subsequently
-rectified (using <em><a href="i.rectify.html">i.rectify</a></em>)
-based on the transformation matrix computed from these points.
-
-<p>     The chosen file is displayed in the upper left quadrant of the
-monitor at a default magnification based on the extent of the
-current active window.
-
-<p>
-<b>RASTER IMAGE</b>
-
-<p>     The raster image option on the menu at the bottom of the
-window allows the user to display any single file in the imagery
-group in the upper right quadrant of the window screen.  The option
-provides the same file selection pick list as is presented when you
-first enter the <em>i.vpoints</em> program.  When you select this option,
-the program will erase the data contained in all of the four
-quadrant windows and will reinitialize all program values.
-
-
-<p>
-<b>VECTOR MAPS</b>
-<p>     The vector maps option on the menu at the bottom of the screen
-allows the user to display vector map data in the upper right
-quadrant of the screen.  After selecting the vector map layer to
-display, a menu selection bar appears along the bottom on the
-screen. This pick list is used to select the line color (blue,
-gray, green, red, white, or yellow) for the selected vector data
-layer.
-<p><b>Refresh</b>
-<p>     The refresh option on the main menu allows the user to
-"refresh" or re-draw the displayed vector data. This function will
-erase all outlines showing the limits of previously zoomed areas. 
-A "yes/no" roompt will appear:
-<pre>
-     Refresh Map ?       NO   YES
-</pre>
-<p><b>Zoom</b>
-<p>     To enlarge a raster or vector image, place the mouse cross
-hairs on the word zoom on the main menu and press the left button. 
-The following menu will be displayed at the bottom. of the screen:
-<pre>
-     CANCEL   BOX   POINT      Select type of zoom
-</pre>
-You have the option to identify the map extent of the zoom window
-using either the mouse to define a box, or the mouse to mark a
-center point from which to enlarge the image.  The box option first
-prompts you to identify a starting corner for the zoom region and
-then allows you to define the area to be zoomed using a rubber band
-box.  The prompts appear as follows...
-<pre>
-     CANCEL    Mark the first corner of region
-
-     CANCEL     Define the region
-</pre>
-After marking the first corner of the region to be enlarged, hold
-down the left button and move the mouse to change the size and
-shape of the rubber band box.  After defining the area to be
-enlarged, press the right button  to accept it.
-
-
-<p>
-The point method for enlarging an image will display a mouse menu
-to guide you in selecting the appropriate enlargement.  To enlarge
-or reduce the magnification factor, place the cursor on the "+" or
-"-" box and press the left button on the mouse.
-<p><p>You may zoom either the raster or the vector display.
-<p>Upon accepting the new region limits, the raster or vector data are
-redisplayed in either the lower left (raster) or lower right
-(vector) windows.
-<p>The extent of the zoomed area is outlined on the unzoomed image in
-the main window area.
-<p>     While the main menu is displayed,  you can mark
-corrosponding control points on the raster and vector
-images or enter map coordinates from the keyboard.  If you
-are using coordinates taken from a reference map, circle
-these points and then use whatever means you have available
-to identify as precisely as possible the coordinate values
-for these points.  Digitizing software is recommended,
-especially <a href="wxGUI.vdigit.html">wxGUI vector digitizer</a>. Once you have
-determined the standard coordinates (for example, UTM's) of
-each circled point, you are ready to mark the points on the
-displayed image.
-<p>     To mark the points on the image, that correspond to the points
-on the standard coordinate map, place the mouse cross hairs on the
-point on the image to be marked (you will probably have to ZOOM to
-find the exact spot) and press the left hand button on the mouse. 
-A diamond shaped symbol will be marked on the image.  The text
-monitor will display the following screen:
-<pre>
-          Point 1 marked on the image at
-          East:  1023.77
-          North:  -164.41
-
-          Enter coordinates as east north:
-</pre>
-<b>Analyze</b>
-<p>
-     After a number of points have been marked (a minimum of 4 for
-a 1st order transformation, 7 for a 2nd order, and 11 for a 3rd
-order), the RMS error of the points marked on the image can be
-checked.  This is done by placing the cross hairs on the word
-ANALYZE on the main menu at the bottom of the monitor.  The
-following error report is superimposed on the monitor:
-<pre>
-
-   error                      image                target
-  #    col  row target   east      north       east      north 
-     
-  1   -0.9  0.0  1.0   1048.5     -144.8   679132.5  4351080.6
-  2    1.0  0.4  1.3   2153.1     -567.2   684314.7  4399001.4
-  .
-  .
-  .
-          Overall rms error  76.85
-</pre>
-
-     The RMS error for the image being rectified is recorded under
-the column "error" and subTITLEd "row' and "col".  In the above
-report, the marked point number 1 is 0.0 rows and -0.9 columns from
-the predicted location calculated by the transformation equation.
-     The RMS error for the target database map is recorded under
-the heading "error"  and the subheading "target".  This is the RMS
-error for the east and the north coordinate values of the target
-map, but it is represented in the table using one general value.
-     The overall RMS error for the image is displayed at the bottom
-of the screen in meters.  Points that generate a high RMS error are
-displayed in red on the monitor.
-     The x,y coordinate values of the point marked on the image
-being rectified are recorded under the heading "image" and the
-subheadings "east" and "north".
-     The standard coordinate values of the point in the target
-database are recorded under the heading "target" and the
-subheadings "east" and "north".
-     If the user would like to exclude or include a point, this can
-be accomplished by placing the mouse cross hairs on the point
-number to be included (if the point is absent) or excluded (if the
-point is displayed) and then pressing the left button on the mouse
-twice.  When a point is excluded, it is not included in the
-calculation of the RMS error, or included in the final
-transformation matrix.  However, it can be retrieved within
-<em>i.vpoints</em> at any time by double clicking with the mouse as
-described above.
-<p>The following menu appears at the bottom of the monitor:
-<pre>
-   DONE   PRINT   FILE   OVERLAY   DELETE ON       Transformation -
--&gt;   1st ORDER   Double click on point to be DELETED
-</pre>
-Selecting DELETE ON will toggle the option to DELETE OFF, the
-toggle option is used to allow the user to physically remove a
-control point from the POINTS file instead of just flagging it as
-an non-active reference point.
-<p><b>Overlay</b>
-<p>Overlay allows the user to overlay the vector map(s) onto the
-raster image.  Overlay can be used to warp (register) and display
-the selected vector map data on top of the raster image contained
-in the upper left window of the color screen.  An inverse
-coordinate transformation is performed using the currently active
-order of transformation (i.e., first, second, or third).
-<pre>
-     Overlay vectors on raster image   NO   YES
-</pre>
-By selecting the 1st ORDER option, the user may select the order of
-transformation desired:
-<pre>
-     Select order of transformation --&gt; 1st Order 2nd Order 3rd Order
-</pre>
-The program will immediately recalculate the RMSE and the number of
-points required.
-<p><b>Quit</b>
-<p>     To exit the <em>i.vpoints</em> program, place the mouse cross hairs on
-the word QUIT at the bottom of the monitor and all of the marked
-points (including coordinates) will be saved.
