AddOns - repozytorium kodu źródłowego

Kod źródłowy dodatków (AddOns) jest udostępniany w repozytorium SVN GRASS-AddOns.


svn checkout https://svn.osgeo.org/grass/grass-addons/ grass-addons

Przeczytaj Jak otrzymać uprawnienia zapisu w repozytorium GRASS-Addons-SVN i napisz na grass-dev listę mailingową jeśli chcesz dołączyć swój moduł do repozytorium.

Kompilacja i instalacja Addons

Przejdź na strony wiki dotyczące kompilacji i instalacji.

W GRASS 6.4 i wersjach następnych użyj modułu g.extension, np., aby zainstalować r.fuzzy.system, uruchom:

g.extension extension=r.fuzzy.system

Aby usunąć zainstalowane dodatki, uruchom

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

Dodawanie czegoś nowego

Najlepiej jest ogłosić dodatek na liście mailingowej użytkowników GRASS, aby inni byli poinformowani o podjętej pracy. Warto również rozważyć dodanie modułu do jednej ze stron Applications.

Autor: Stefano Costa


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. screenshot.

    ===== v.lda.py =====
v.lda.py is a Python script for calculating Ian Johnson's (U. Sidney) Local Density Analysis values. This can be used in two ways. When only one vector points file is entered, it serves to measure clustering of point data at different neighborhood radii. When two different point files are entered, it measures the the co-occurence of the points from the two files. There is an option to export the data into a cvs format file for easy plotting in a spreadsheet or statistical program like R.
    ===== v.nn.py =====
v.nn.py is a Python script for calculating the nearest neighbor coefficient of a single vector points file--as an index of clustering--or of two points files--to provide an index of the correspondence between the points in one file and points in a different file.

v.surf.icw is an IDW interpolation method using true distance cost instead of euclidean shortest distance, i.e. as the fish swims around an island not as the bird flies. This will cleanly travel around hard barriers and a cost surface map may be used to model expensive-cross barriers. Input data points do not need direct line of sight to be considered, but should be kept to less than one hundred as the module becomes very computationally expensive. A number of radial basis function options are available. (screenshot)

r.hazard.flood is an implementation of a fast procedure to detect flood prone areas. The exposure to flooding may be delineated by adopting a topographic index (TIm) computed from a DEM. The portion of a basin exposed to flood inundation is generally characterized by a TIm higher than a given threshold, tau. The threshold is automatically determinated from the cellsize. The proposed procedure may help in the delineation of flood prone areas especially in basins with marked topography. The use of the modified topographic index should not be considered as an alternative to standard hydrological-hydraulic simulations for flood mapping, but it may represent a useful and rapid tool for a preliminary delineation of flooding areas in ungauged basins and in areas where expensive and time consuming hydrological-hydraulic simulations are not affordable or economically convenient.

r.traveltime computes the travel time of surface runoff to an outlet. The program starts at the basin outlet and calculates the travel time at each raster cell recursively. A drainage area related threhold considers even surface and also channel runoff. Travel times are derived by assuming kinematic wave approximation.

  • i.dn2potrad.l[5,7] is an attempt to get ET potential from DN of Landsat 7 (Careful! No Atmospheric correction!).
  • i.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.
  • i.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 i.eb.eta.
  • i.evapo.SENAY creates actual evapotranspiration following the regional method of Senay (2007).
  • i.lmf creates a Local Maximum Fitting on the temporal dimension of the multi-date input dataset, working, but more precision still to be added.
  • i.vi.mpi is the mpi version of i.vi for cluster GRASS GIS education (no speed up here!) Autor: Shamim Akhter
  • i.modis.stateqa extracts State Quality Assessment information from Modis 500m (MOD09A) products.
  • i.water creates a Water Mask from NDVI and Albedo, or specifically for Modis: NDVI and Band 7.
  • i.wi creates a given Water Index (only one so far).

This module allows a search of GCP's on two raster-maps with differents levels of automation. The manual search is the default search, so it's possible to determine the GCP's manually with the mouse (like i.points). Semiautomated search: The user determines with the mouse some correspondent areas (with a discrete precision) in the two maps and the module searches itself the GCP's in these areas. Automated search: At the start of module the user has to load the maps that the algorithm uses to the search, so it is recommended to use the maps filtered with the filters DIVERSITY or STDDEV (of GRASS) with a window of 3x3 or 5x5 pixels. However, the algorithm sometimes works well with the original maps too.

Note: This code is basically an improved i.points (from 2004). Subsequent changes in i.points haven's been ported here yet.
