<DIV>I have a data sets with the following characteristics:</DIV>
<DIV> </DIV>
<DIV>Numer of rows = 8384</DIV>
<DIV>Number of columns = 9102</DIV>
<DIV> </DIV>
<DIV>XY corner coordinates :</DIV>
<DIV>Lower left: -4462500.000, -3999500.000</DIV>
<DIV>Upper left: -4462500.000, 4384500.000</DIV>
<DIV>Upper right: 4639500.000, 4384500.000</DIV>
<DIV>Lower right: 4639500.000, -3999500.000</DIV>
<DIV> </DIV>
<DIV>Projection used: Lambert azimutal equal area</DIV>
<DIV> units = meters</DIV>
<DIV> pixel size = 1000 mts</DIV>
<DIV> Radius of sphere of influence = 6,370,997, mts</DIV>
<DIV> Longitud of origen = 100 00 00W</DIV>
<DIV> Latitud of origen = 45 00 00N</DIV>
<DIV> False easting = 0.0</DIV>
<DIV> False northing = 0.0</DIV>
<DIV> </DIV>
<DIV>I can get it with "r.in.bin ..." in "location 1", but i need it in lat-long projection and when i try to get it in "location 2" using the following parameters into the "PROJ_INFO" file ;</DIV>
<DIV>type of projection= ll (lat-lon), datum= wgs84, gridnads= conus, ellips= wgs84.</DIV>
<DIV>With g.region n=90 s=-90 w=-180 e=180 res=0.008333 (30 secs) and using the "r.proj ..." comand , i obtain my transformation with the following coordinates of the raster new image; n=40 s=-36 w=-49 e=51res=0.008333, but it's wrong because the coordinates must be aproximately n=80 s=10 w=-170 e=-40. </DIV>
<DIV>How can i solve my problem?, which are the correct parameters in the "PROJ_INFO" file?, i try with ellips = sphere and can't get results, where i must to definite lat, lon of origen and false northing and easting?</DIV>
<DIV> </DIV>
<DIV>The data sets are int the urls:</DIV>

<DIV><A href="http://lpdaac.usgs.gov/gtopo30/hydro/namerica.asp">http://lpdaac.usgs.gov/gtopo30/hydro/namerica.asp</A></DIV>
<DIV> </DIV>
<DIV>and can be of the type : Download <A href="http://edcftp.cr.usgs.gov/pub/data/gtopo30hydro/na_dem.tar">HYDRO1k DEM for North America</A> as a tar file (28.2 MB).</DIV>
<DIV> </DIV>
<DIV>I wait that anyone can help me in this.</DIV>
