|
| |
| : [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. [http://phygeo7.geo.uni-augsburg.de/gis2/scripts/v.digatt.png screenshot].

|
| |
| : v.surf.krige is a script that do a surface interpolation from vector point data by Kriging method. The interpolated value of a cell is determined by using an omnidirectional variogram model fitted starting from model parameter given by user shown from the experimental semi variogram produced by v.variogram. The script can perform also the Leave-One-out cross validation to test the variogram model "fitted by eye" and an automatic fitted variogram model. The cross validation helps the user to choose the best variogram model to interpolate own data.

|
| |
| : [http://svn.osgeo.org/grass/grass-addons/raster/r.hazard.flood/ 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.

| ==== i.points.auto ====
| |
|
| |
| 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 {{cmd|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.

| : [http://trac.osgeo.org/grass/browser/grass-addons/imagery/i.points.reproj i.points.reproj] is a shell script that will use cs2cs to reproject the target coordinates of a group's POINTS file. By running i.rectify directly to the new target projection, a generation of resampling data loss can be avoided (versus i.rectify + r.proj). On the other hand, i.rectify does not calculate cell resolution well if the map is to be rotated ([http://intevation.de/rt/webrt?serial_num=3296 bug #3296]), in those cases i.rectify+r.proj may be the better option.

It can be obtained with {{cmd|r.sun}} (parameter incidout), and then calculating its cosine with float precision. Correction methods: cosine, minnaert, percent, c-factor.
