Re: [GRASS-user] r.soils.texture question
*.dat files are derived from TALCPP ( https://www.tandfonline.com/doi/abs/10.1081/CSS-120017410). The values describe polygons coordinates for different class inside the texture triangle. In r.soils.texture is implemented an algorithm to check if a single point is inside or outside a texture polygon. If the point is inside it is labeled with the correspondent texture code and used to build a texture map.

I've attacched the last version that works in my machine and a description.html. I'm gratefully you if yuo can try it. Thank for patient! DESCRIPTION The r.mcda.ahp Generate a raster map classified with analytic hierarchy process (AHP) [Saaty, 1977 and Saaty Vargas, 1991] (GRASS python Script) NOTES It is mandatory to build a pairwise comparation table with the same order of input of criteria maps in the criteria field. Example: r.mcda.ahp criteria=reclass_slope,reclass_sand,reclass_elev pairwise=pairwise output=outputMap The file pairwise has to have a structure like this: #start file 1.0, 0.2, 3.0 5.0, 1.0, 5.0 0.3, 0.2, 1.0 #comment: order: reclass_slope,reclass_sand,reclass_ #end file The first row and first column are related to the first criteria (reclass_slope in our case); the second row and second column are related to the second criteria (reclass_sand in our case) and the third row and third column are related to the third criteria ( reclass_elev in our cas), and so on.

Re: [GRASS-user] Re: about Analytic Hierarchy Process (AHP)
Hi, r.soils.texture calculates the soil texture based on several schemes (USDA, FAO, International); but I've just completed a simple addon (in python), even if experimental, for the use of AHP in GRASS. It is named * r.mcda.ahp* and is in mcda package ( https://svn.osgeo.org/grass/grass-addons/grass6/raster/mcda/). You can download and isntall the module in your grass gis and in document.html there are a bits of advice for the use. I'm available for support you for the use and of course, for feedback. I'm gratefully if someone could try other mcda module for test and improve it. gianluca Il giorno 11 dicembre 2011 22:21, Markus Neteler nete...@osgeo.org ha scritto: On Sun, Dec 11, 2011 at 8:30 AM, leonidas leonidas_lia...@yahoo.gr wrote: Is there any tutorial about AHP in SAGA?
