Re: [GRASS-user] map algebra logical operators on DCELL rasters not admitted? maybe docs should outline it

Ah ok Glynn, I always meant logical operators. Probably I copied the error from a different test. If logical operator is applied to, sat, Byte data it gives true/false results, e.g. if(A && B,1, 0) behaves correctly even with cell values values greater then 1. That's why I expected it to work

Thanks for the clear explanation Glynn. Maybe this behaviour could be esplicited inside the docs... giovanni Il 22/ott/2015 23:35, "Glynn Clements" ha scritto: > > G. Allegri wrote: > > > If logical operator is applied to, sat, Byte data it gives true/false > >

Re: [GRASS-user] Something wrong: Reprojection of raster maps in various platforms: projected coordinates are different

I could not reach the solution till now even after following the steps told in previous posts. I know I am making a silly mistake. This is the projection information of the target location: +proj=laea +lat_0=30 +lon_0=-96 +x_0=0 +y_0=0 +datum=NAD83 +units=m +no_defs *GRASS 7.1.svn

Re: [GRASS-user] External raster from PostGIS

Hi Markus, How do I implement such command in GRASS GIS? I have tried with r.external because I have done the same thing with v.external. I'have tried as well with r.in.gdal but notthing. If i use v.in.ogr I can import vectors from PostGIS. Lorenzo 2015-10-22 17:55 GMT+02:00 Markus Neteler
