.SH wxGUI RLi Setup
.SH DESCRIPTION
The \fBg.gui.rlisetup\fR is a \fIwxGUI\fR
component which allows the user to create a configuration file
for the analytical \fIr.li\fR modules. For a general introduction, see
the r.li overview.
.br
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.
.br
The program is completely interactive and uses a GUI to help you
in your choices.
.SS Analysis methods
Definition of creation of sampling area:
.RS 4n
.IP \(bu 4n
Whole map layer: use entire area selected above,
.IP \(bu 4n
Regions: select one to many subareas via mouse,
.IP \(bu 4n
Sample units: automated selection of sampling area (for details see below)
.RS 4n
.IP \(bu 4n
Random nonoverlapping,
.IP \(bu 4n
Systematic contiguous,
.IP \(bu 4n
Systematic noncontiguous,
.IP \(bu 4n
Stratified random,
.IP \(bu 4n
Centered over sites (vector points).
.RE
.IP \(bu 4n
Moving window: rectangular or circular with size
.RE
.PP
Definition of region for analysis:
.RS 4n
.IP \(bu 4n
Whole map layer: entire map (current region),
.IP \(bu 4n

.SS Usage details
The startup window shows your configuration files, you can:
.PP
\fBTODO: description below needs further updates\fR
.PP
.IP
.IP \fB1\fR
\fI\fBView/Edit\fR\fR (Load a file) from the shown list: the
configuration is shown in a small text editor window.
Configuration files are saved in the folder
C:\(rsUsers\(rsuserxy\(rsAppData\(rsRoaming\(rsGRASS7\(rsr.li\(rs (MS\-Windows) or
$HOME/.r.li/ (GNU/Linux) (the file name can be
defined by the user). The output or an analysis can either be a new raster
map (in case of using a \(dqmoving window\(dq analysis) or be an ASCII text file
(when not performing a \(dqmoving window\(dq analysis) containing the result.
Such text file will be saved in the folder
C:\(rsUsers\(rsuserxy\(rsAppData\(rsRoaming\(rsGRASS7\(rsr.li\(rsoutput\(rs
(MS\-Windows) or $HOME/.grass7/r.li/output/ (GNU/Linux).
.br
All dimensions are percentages of raster rows or columns.
.IP \fB2\fR
\fI\fBCreate\fR\fR a new configuration file: used for creating
a new configuration file in an interactive way, in three steps:
.IP
.IP \fB2.1\fR
Choose file name and maps to use for setting:
.RS 4n
.IP \(bu 4n
\fIName for new configuration file\fR(required): the name
of new configuration file
.IP \(bu 4n
\fIRaster map name to use to select areas\fR (required):
the name of raster map used for selecting sampling areas
.IP \(bu 4n
\fIVector map to overlay\fR (optional): name of a
vector map used for selecting sampling areas
.RE
.IP \fB2.2\fR
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:
.RS 4n
.IP \(bu 4n
\fIWhole map layer\fR: the sample frame is the whole map
.IP \(bu 4n
\fIKeyboard setting\fR: the user enters the coordinates in
cells of upper left corner of sampling frame and its length in
rows and columns.
.IP \(bu 4n
\fIDraw the sample frame\fR: the user draws the sample frame
on map using mouse.
.RE
.IP \fB2.3\fR
Set the sample areas. The sample areas are simply the areas to
analyze. They can be defined in five ways (see the picture below):
.RS 4n
.IP \(bu 4n
\fIWhole map layer\fR: the sample area is the whole sample
frame
.IP \(bu 4n
\fIRegions\fR: the user enters the number of areas and then
draws them using mouse.
.IP \(bu 4n
\fISample units\fR: they are areas of rectangular or circular
shape. The user can define them using keyboard or mouse.
.RS 4n
.IP \(bu 4n
keyboard: the user define the shape of sample unists and
their disposition:
.RS 4n
.IP \(bu 4n
\fIRandom non overlapping\fR: the user specifies
the number of sample units and they are placed in a
random way at runtime. It is guaranteed that the
areas do not intersect themselves.
.IP \(bu 4n
\fISystematic contiguous\fR: the defined sample
is placed covering the sample frame, side by side
across rows.
.IP \(bu 4n
\fISystematic non contiguous\fR: the same as above,
but here ever rectangle is spaced from another by
a specified number of cells.
.IP \(bu 4n
\fIStratified random\fR: the sample frame is
divided in \fIn\fR strats of rows and \fIm\fR strats of columns
(\fIn\fR and \fIm\fR are given by user), then the specified
number of sample areas are placed in a random way,
one for every \fIm*n\fR areas defined by strats.
.IP \(bu 4n
\fICentered over sites\fR: the sample areas
are placed into sample frame centering them on points
in site file.
.RE
.IP \(bu 4n
mouse: the user chooses the shape and then draws the
specified number of sample areas on map.
.RE
.IP \(bu 4n
\fIMoving Window:\fR 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.
.IP \(bu 4n
\fISelect areas from the overlaid vector map\fR:
the sample areas are defined by the vector map selected above.
For every cat in vector map, the procedure prompts the
user if they want 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.
.RE
.PP
.IP \fB3\fR
\fI\fBRemove a file\fR\fR the selected file is deleted from the
available configuration files.
.IP \fB4\fR
\fI\fBHelp\fR\fR: open this help text.
.IP \fB5\fR
\fI\fBClose\fR\fR module window.

.SH NOTES
Configuration files are raster map independent because areas are saved using
relative coordinates.

.SH EXAMPLES
.SS Moving window analysis on full region
\fITODO: update examples to new g.gui.rlisetup dialog:\fR
.PP
Example for a 7x7 moving window analysis on full region, the output
is a raster map:
.PP
Click on \(dqNew\(dq, then:
.RS 4n
.IP \(bu 4n
Configuration file name: \(dqmovwindow7\(dq
.IP \(bu 4n
Raster map name to use to select areas: \(dqforests\(dq
.RE
1. Setup sampling frame:
.RS 4n
.IP \(bu 4n
Define a sampling frame (region for analysis): \(dqWhole map layer\(dq, then \(dqOK\(dq
.RE
2. Setup sampling frame
.RS 4n
.IP \(bu 4n
Define sampling areas: \(dqMoving window\(dq, then \(dqOK\(dq
.IP \(bu 4n
Then click on \(dqUse keyboard to define moving window dimension\(dq
.RE
Select type of shape:
.RS 4n
.IP \(bu 4n
[x] Rectangular
.IP \(bu 4n
Width size (in cells)?: \(dq7\(dq
.IP \(bu 4n
Height size (in cells)?: \(dq7\(dq
.IP \(bu 4n
Then \(dqSave settings\(dq
.RE
3. Save settings: click on button
.br
(4.) Close
.PP
Now an anaysis can be performed using one of the analytical modules, e.g.
.br
.nf
\fC
g.region raster=forests \-p
r.li.patchdensity input=forests conf=movwindow7 output=forests_p_dens7
r.univar forests_p_dens7
\fR
.fi
The result is the new raster map \(dqforests_p_dens7\(dq which shows (in this example)
the patch density of the forest areas.
.br
See the respective modules for further examples.
.SS Whole region analysis
Example for a whole region analysis, the output is a text file:
Click on \(dqNew\(dq, then:
.RS 4n
.IP \(bu 4n
Configuration file name: \(dqwhole_region\(dq
.IP \(bu 4n
Raster map name to use to select areas: \(dqlsat7_2000_40\(dq
.RE
1. Setup sampling frame:
.RS 4n
.IP \(bu 4n

.RE
2. Setup sampling frame
.RS 4n
.IP \(bu 4n
Define sampling areas: \(dqWhole map layer\(dq, then \(dqOK\(dq
.RE
3. Save settings: click on button
.br
(4.) Close
.PP
Now an anaysis can be performed using one of the analytical modules, e.g.
