<div>Dear R-gurus,</div>
<div> </div>
<div>I just started to use GRASS, and I am working with a (almost to me) very large dataset into GRASS 6.3.0 NATIVE WINDOWS</div>
<div>I imported an Erdas image file using Gdal. Apparently I looks fine, because GRASS understood and create a Mapset with all informations contained on my IMG file (like projection, number of cells, bounding box, etc.).</div>
<div> </div>
<div>The raster map is 60,000x48,000 pixels.</div>
<div> </div>
<div>I tryed display my raster map (it is a binary map with values 0 and 1), but I can see the binary map.</div>
<div>How can I display my raster map on Map Display 1? I notice that "d.raster teste" send the output to .tmp directory (or something like).</div>
<div> </div>
<div>But my biggest problem is that I need to generate a Distance Map from those pixels which values is 1.</div>
<div> </div>
<div>I tryed "r.buffer input=test output=teste_buffer distances=50,100" (it is in meters)</div>
<div>but GRASS return a erros message telling that canīt allocate memory</div>
<div> </div>
<div>Below is the <a href="http://r.info">r.info</a> for the raster that I am trying to "see" and to "buffer".</div>
<div> </div>
<div>My computer is running windows XP, and I have 4Gb of ram memory.</div>
<div> </div>
<div>Help are welcome.</div>
