<div>Hello!</div><div><br></div><div>My name is Ivan.</div><div>I have been trying to import a GIS raster flie to GRASS64.</div><div>I do the next proucedure in Ubuntu 10.04:</div><div><br></div><div>-I run grass64</div><div>
-I define a new location using the EPSG code: 32161 (based in the information at the end of this email)</div><div>-When Grass asks me: Select datum transformation parameters, </div><div> I choose the second one: (Used in whole nad83 region. towgs84 = 0.000, 0.000, 0.000)</div>
<div>-Then I enter in the PERMANENT folder.</div><div><br></div><div>And then I do this:</div><div><div><br></div><div><font class="Apple-style-span" color="#33CCFF">r.in.gdal input=/home/ivan/grassdata/prgap_landcover.img output=puertoRico</font></div>
