* [http://phygeo7.geo.uni-augsburg.de/gis2/scripts/v.digatt v.digatt] (shell script) Interactively assign numeric table attributes to series of vector objects. It is meant to be effective by avoiding to type in the attribute value for all single objects again and again. The user is prompted for typing in an attribute value which is assigned to all objects selected by mouseclick afterwards. Next the display is redrawn after updating the table column. Zooming allows to change the region before the old value can be reused or a new one can be typed in (or copied by mouse from another object) in order to assign it to the next series of objects etc. It is tested not very extensively yet. Therefore better work with a copy of your map and consider using v.digit or d.what.vect -e alternatively.

* The GRASS Image Processing Environment (GIPE) has USLE, Energy-balance and radiance-reflectance correction models. <BR>'''Author:''' Yann Chemin (unless specified otherwise).<br> It is available by anonymous reading through this command (thanks Markus!):<br>
 
svn co https://grasssvn.itc.it/svn/grassaddons/trunk/grassaddons grassaddons/gipe
 
<br>
 
- r.usler creates USLE R factor (Rainfall erosivity) from annual precipitations.
 
It has 4 methods, Morgan, Roose, Foster and El-Swaify to choose from.
 
'''Authors:''' Natalia Medvedeva and Yann Chemin <br>
 
- r.uslek creates USLE K factor (soil erodibility) from sand, clay, silt fractions
 
and organic matter fraction. Based on USDA 1951 (p209) quoted in FAO World Soil CD,
 
and from some generic [soil class+OM] to K conversion table. <br>
 
- r.albedo creates Albedo. Albedo is the shortwave surface reflectance in the range
 
of 0.3-3 micro-meters. This module takes Modis, Aster, Landsat or AVHRR individual
 
surface reflectance bands to calculate Albedo. This module is a precursor to r.sun
 
or any Energy-Balance related processing. <br>
 
- r.eb.* are a set of 10+ GRASS modules that together perform the main functions of
 
the SEBAL model (Bastiaanssen, 1995). Those functions include (but are not limited to)
 
Soil heat flux, sensible heat flux, net radiation, evaporative fraction at satellite
 
overpass, diurnal actual evapotranspiration, momentum roughness length, etc. These
 
modules are also part of any Energy-Balance related processing. <br>
 
- r.evapo.potrad creates diurnal Potential evapotranspiration assuming all net radiation
 
becomes ET, according to SEBAL model (Bastiaanssen, 1995). This module also has a flag for
 
diurnal net radiation as required by SEBAL in r.eb.eta. <br>
 
- r.vi creates a given Vegetation index from a list of 13 of them, most of them only
 
requiring Red and NIR. Updated to accept all types of input data.
 
'''Authors:''' Baburao Kamble and Yann Chemin <br>
 
- r.vi.mpi is the mpi verion for cluster GRASS GIS education (no speed up here!).
 
'''Author:''' Shamim Akhter <br>
 
- r.dn2ref.l7, r.dn2ref.ast create top of atmosphere reflectance for Landsat 7ETM+ and
 
ASTER. These modules also have a flag for radiance output. Updated r.dn2ref.l7 to read .met
 
calibration file.  <br>
 
- r.dn2full.l7 is an attempt to get all bands of Landsat7 calibrated and corrected to
 
either reflectance or temperature, reads only the .met file.  <br>
 
- r.dn2potrad.l7] is an attempt to get ET potential from DN of Landsat 7 (Careful! No
 
Atmospheric correction!).  <br>
 
- r.biomass creates biomass growth map from fPAR, lightuse efficiency, water availability
 
(or evap.fraction), Lat, doy and tsw.

This page contains references to user contributions and add-ons (the original GRASS GIS software can be downloaded here).

Overview

GRASS GIS 7 Addons Manual pages - a complete overview of available Addons

Building and installing AddOns

Common users

Graphical user interface:
We recommend to use the wxGUI Extension Manager (Settings -> Addon extensions -> Install extensions from addons) to install Addons.

Command line:
You can also use the g.extension module, e.g. to install r.fuzzy.system run:

g.extension extension=r.fuzzy.system

To remove installed AddOns run

g.extension extension=r.fuzzy.system operation=remove

Power users (not recommended for Windows users)

For manual compiling see the compile and install wiki page.

AddOns source code repository

The AddOns source code is hosted in GRASS-AddOns SVN repository.

Adding something new

How to obtain write-access

Please read how to get write access to the GRASS-Addons-SVN repository and contact the grass-dev mailing list if you would like to host your module there.

Please announce your add-on to the GRASS users' mailing list so that others may be aware of your work. Also please consider adding your module to one of the Applications pages.

Copyright and licensing information

Please be sure to include copyright and licensing information in the header comments of your code so that others may know how they can use, extend, modify, and redistribute your work.

e.g. at the top of a shell script:

Coding standards

Please have a look at our SUBMITTING for C-programs, SUBMITTING_PYTHON for Python scripts or SUBMITTING_SCRIPTS for Bash scripts coding standards before submitting here.

Documenting your code

You can have an help page template auto-generated by using the GRASS command line parser with the --html-description command line option. Please, see also the g.parser help page.

Miscellaneous Add-ons

  • utm_which_zone.sh is a shell script to determine UTM zone from Lat/Lon input. Requires Octave or Matlab to be installed. A shell-only version is available which only requires awk.
    Authors: Hamish Bowman (Octave part), Markus Neteler (shell script wrapper), Daniel Calvelo (sh+awk version)


  • Perl scripts for converting data forth and back between Excel files and PostgreSQL: pg2xls.pl reads data from PostgreSQL and produces an excel workbook; xls2sql.pl reads excel files and outputs SQL statements to be fed into an RDBMS. Both scripts need modules from CPAN, especially Spreadsheet::ParseExcel for xls2sql.pl and Spreadsheet::WriteExcel::FromDB and its dependencies for pg2sql.pl. Check the source headers for more info.
    Authors: Daniel Calvelo (xls2sql.pl), Markus Neteler (pg2xls.pl)


  • dbf2sql is a Perl script for translating dbf-tables into a sql-command. dbf-tables are read using dbfdump-command from dbd-xbase-perl module (dbd::xbase and getopt::long have to be installed from CPAN first). There are problems, if the last column of the table contains characters. Suggestions for improvements welcome!
    Author:Wolfgang Qual


  • azimuth2.c is a small C program to calculate the azimuth and length of vector lines exported by GRASS-GIS as ASCII files (like this: v.out.ascii input=vector output=ascii format=standard). It is useful for create rose diagrams of lineament maps. Improvements on the original code after suggestions by Örs Téglásy, Hungary.
    Author: Carlos Henrique Grohmann


  • ann.* is the set of GRASS modules (in python) which implements artificial neural network using FANN library. The package requires Fast Artificial Neural Network Library (FANN) v2.x.
    Author: Pawel Netzel


  • csv_dequote.pl is a Perl script to convert comma separated .csv files (including "quoted" text strings containing commas) into a form ready for v.in.ascii. Comma separators are converted to pipes (|), commas in quoted strings are preserved, and "quotes" are removed where it is appropriate to do so. It doesn't need GRASS to run, but it does need the Text::CSV Perl Module (apt-get install libtext-csv-perl).
