What do you mean exactly with creating a raster from a coordinate pair? If you want to align a raster to your coordinates you might have a look into g.region and set appropriate resolution and extend coordinates.
To create a raster based on coordinates, eg. set a raster value at a specific coordinate pair to a specific value you could use r.mapcalc: E.g. Set the value 1 at the cell x=52, y=10 r.mapcalc "newmap = if(abs(x()-52.0)<0.001 && abs(y()-10.00)<0.001, 1)" If you know the specific row and column and resolution you could also use: r.mapcalc "newmap = if(row()-1 == int(($n-10.0)/$nsres) && col()-1 == int((52.0-$w)/$ewres), 1)" Thanks to Glynn who taught me these things some time ago on the mailing list :) /Johannes On Tue, Dec 10, 2013 at 1:02 PM, aborruso <[email protected]> wrote: > Hi all, > is there some grass raster command to create a raster starting from a > coordinate pair? > > Something like r.createraster input=x,y output=myraster > > Thank you, > > Andrea > > > > -- > View this message in context: > http://osgeo-org.1560.x6.nabble.com/Create-a-raster-starting-from-a-coordinate-pair-tp5093513.html > Sent from the Grass - Users mailing list archive at Nabble.com. > _______________________________________________ > grass-user mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/grass-user >
