SYNOPSIS
r.out.maxent_swd
r.out.maxent_swd --help
r.out.maxent_swd [-z] [alias_input=name] [env_maps=name[,name,...]] [alias_names=string] [bgr_output=name] [alias_output=name] [bgr_mask=name] [species_masks=name[,name,...]] [species_output=name] [species_names=string] [null_value=integer] [--overwrite] [--help] [--verbose] [--quiet] [--ui]
Flags:
- -z
- Zoom computational region to species data (may speed up processing)
- --overwrite
- Allow output files to overwrite existing files
- --help
- Print usage summary
- --verbose
- Verbose module output
- --quiet
- Quiet module output
- --ui
- Force launching GUI dialog
Parameters:
- alias_input=name
- File containg map and alias name(s) for environmental parameter(s)
- env_maps=name[,name,...]
- Environmental parameter map(s)
- alias_names=string
- Alias names for environmental parameter map(s)
- bgr_output=name
- Output SWD file for the environmental data of the background landscape
- alias_output=name
- CSV-like output file with alias names in first column and map names in second column, separated by comma
- bgr_mask=name
- Map to be used as mask for the background landscape
- species_masks=name[,name,...]
- Raster map(s) of specie occurence
- species_output=name
- Output SWD file for the specie(s) related environmental data
- species_names=string
- Alias-name(s) for species to be used in MaxEnt SWD file instead of map names, separated by comma (default: map names).
- null_value=integer
- Integer representing NO DATA cell value (default: -9999)
- Default: -9999
The script is intended to produce a set of SWD files as input to MaxEnt >= 3.3.3e
using
r.stats.
The SWD file format is a simple CSV-like file file format as described in Elith et al. 2011.
Generally it looks like:
specie_name,X,Y,parameter_1,parameter_2,...
your_specie,1.1,1.1,2,4.7,...
The first column always contains the name of the species, followed by
two columns for the X- and Y-coordinates. Then each column
represents one environmental parameter. In contrast to
r.stats
only integer values are accepted to represent NO DATA.
A background SWD file is always produced while species output can be omitted.
Multiple species can be processed, but each has to be in an
individual raster map. Map names of the maps containing the environmental
parameters can be replaced by short names, which should be used
in MaxEnt >= 3.3.3.e.
Results from MaxEnt can either be imported using
r.in.xyz or
calculated from MaxEnt lambdas file using the
r.maxent.lambdas.
