NAME  - Configuration editor for'index'


       raster, landscape structure analysis

SYNOPSIS help  [--verbose]  [--quiet]

DESCRIPTION   creates  and  shows  configuration  files for the others programs. For a
       general introduction, see
       The configurations are raster map independent, it means that you can use a file created on
       a raster map for analyze any other you have.
       The program is completely interactive and uses a GUI to help you in your choices.

   Analysis methods
       Definition of region for analysis:

                      Whole maplayer: entire map (current region),

                      Keyboard setting: based on keyboard selection for region definition,

                      Draw the sampling frame: based on interactive region selection via mouse.
       Definition of creation of sampling area:

                      Whole maplayer: use entire area selected above,

                      Regions: select one to many subareas via mouse,

                      Sample units: automated selection of sampling area (for details see below)

                             Random nonoverlapping,

                             Systematic contiguous,

                             Systematic noncontiguous,

                             Stratified random,

                             Centered over sites (vector points).
              Moving  window:  rectagular  or  circular with size Select areas from the overlayed
              vector map (for details see below)

   Usage details
       The startup window shows your configuration files, you can:

       1      Load a file: the configuration is printed using rectangles with  differents  colors
              (green for the raster map, red for the sample frame and blue for the sample areas),
              and other notes (disposition of sample areas etc).  The configuration file is saved
              in ~/  Configuration output files are raster if moving window
              disposition was selected, otherwise they are in ~/ folder.

              All dimension are percentage of raster rows or columns.

       2      Create a new file: this create a new configuration file in an interactive  way,  in
              three steps

               Choose file name and maps to use for setting:

                      Configuration file name (required): the name of new configuration file

                      Raster map name (required): the name of raster map to use for setting

                      Vector  map  to  overlay  (optional):  name  of  a vector map to overlay in

                      Site file to overlay (optional): name of  vector  map  of  points  type  to
                     overlay in setting

               Set  the sampling frame. The sample frame is a rectangular area which contains all
              the areas to analyze. It can be defined in three ways:

                     Whole map layer: the sample frame is the whole map

                     Keyboard setting: the user enters the coordinates in  cells  of  upper  left
                     corner of sampling frame and its length in rows and columns.

                     Draw the sample frame: the user draws the sample frame on map using mouse.

               Set  the  sample areas. The sample areas are simply the areas to analyze. They can
              be defined in five ways (see the picture below):

                     Whole map layer: the sample area is the whole sample frame

                     Regions: the user enters the number of  areas  and  then  draws  them  using

                     Sample  units: they are areas of rectangular or circular shape. The user can
                     define them using keyboard or mouse.

                            keyboard: the user define  the  shape  of  sample  unists  and  their

                                   Random  non  overlapping:  the  user  specifies  the number of
                                   sample units and they are placed in a random way  at  runtime.
                                   It is guaranted that the areas do not intersect themselfs.

                                   Systematic  contiguous:  the defined sample is placed covering
                                   the sample frame, side by side across rows.

                                   Systematic non contiguous: the same as above,  but  here  ever
                                   rectangle  is  spaced  from  another  by a specified number of

                                   Stratified random: the sample frame is divided in n strats  of
                                   rows and m strats of columns (n and m are given by user), then
                                   the specified number of sample areas are placed  in  a  random
                                   way, one for every m*n areas defined by strats.

                                   Centered  over  sites: the sample areas are placed into sample
                                   frame centering them on points in site file.

                     2.20   mouse: the user chooses the shape and then draws the specified number
                            of sample areas on map.

              2.21   Moving  Window: the user defines a rectangular or circular area, it is moved
                     over all the raster increasing only of a cell for every move(in  columns  if
                     possible,  if  not in rows).  It produces a new raster containing the result
                     of all analysis.

              2.22   Select areas from the overlayed vector map: the sample areas are defined  by
                     the  vector  map selected above.  For every cat in vector map, the procedure
                     prompts the user if he wants to include it as sample  area.   The  resulting
                     configuration  file  can be used only with the specified raster map, and the
                     procedure can be used only if whole map layer is selected as sampling frame.

              3      Remove a file the selected file is deleted from the available  configuration
