benizar / _plr_clasif_textural.R
Created October 11, 2013 11:06
This code creates a pl/R function for creating texture triangles directly from a PostgreSQL database.This example is composed by three pl/R files (_plr_clasif_textural_usage.sql, _plr_clasif_textural.sql and _plr_clasif_textural.R). This code is quite old and it would look better using the "The Soil Texture Wizard" package. Want more info? Visit…

benizar / R_SAGA_GIS_example.R
Created October 11, 2013 10:50
This is a very basic example for using SAGA GIS from the R console. Load a polygon shapefile and a raster file and then split the raster into parts. Want more info? Visit our www.gisandchips.org blog (http://www.gisandchips.org/2011/01/13/usando-rsaga-para-procesar-un-raster-grande-por-partes/#more-1692)
## Abrimos la consola de R y cargamos la librería
library(RSAGA)
## Seleccionamos el fichero raster que queremos trocear y una capa vectorial que queramos usar como límites. También especificamos el directorio donde van los outputs. Para trabajar con Windows recomiendo rutas sin espacios.
raster<- file.choose()
poligonos<- file.choose()
directorio <-choose.dir()
## Consultamos hasta encontrar la herramienta que nos separa un shapefile en varios, obteniendo un shapefile por cada polígono, o lo que quisiéramos. Por ejemplo:
## rsaga.get.modules("shapes_grid")
