<DIV>What does GDALINFO return if you query your mapgeo.bmp and then subsequent
mapgeo.tif ?</DIV>
<DIV> </DIV>
<DIV>I have had problems with not having generated a TFW and then try to perform
warps. I believe there is a switch for GDAL translate that will generate a TFW
on translation eg <STRONG>TFW=YES.</STRONG></DIV>
<DIV> </DIV>
<DIV>Also the in the -s_srs I use +proj=latlong.</DIV>
<DIV> </DIV>
<DIV>Anyway see how you go. </DIV>

users,</SPAN></DIV>
<P><SPAN class=085080608-06042006>I</SPAN> downloaded and
installed <SPAN class=085080608-06042006>GDAL Binaries in
</SPAN>FWTools.</P>
<P>I tried to reproject a BMP file with ESRI world file (BPW) <SPAN
class=085080608-06042006>using "GDALWARP.EXE" </SPAN>but haven't been able to
it.</P>
<P>I need your help.</P>
<P>The procedure I followed is below:</P>
<P>rem gdal_translate.exe for bmp --> geotiff conversion:</P>
<P>gdal_translate mapgeo.bmp mapgeo.tif </P>
<P>Rem OK, eg. NO PROBLEM</P>
<P></P>
<P>rem geotifcp.exe for esri world file --> into geotiff file:</P>
<P>geotifcp -e mapgeo.bpw mapgeo.tif</P>
<P>Rem OK, eg. NO PROBLEM</P>
<P>PROBLEM:</P>
<P>rem gdalwarp.exe for geo --> utm reprojection:</P>
<P>FIRST ATTEMPT:</P>
<P>D:\FWTools\bin>gdalwarp -t_srs "+proj=utm +zone=36 +datum=WGS84"
mapgeo.tif maputm.tif Creating output file that is 518P x 442L.</P>
<P>Processing input file mapgeo.tif.</P>
<P>A target coordinate system was specified, but there is no source coordinate
system. Consider using -s_srs option to provide a source coordinate
system.</P>
<P>Operation terminated.</P>
<P>SECOND ATTEMPT:</P>
<P>D:\FWTools\bin>gdalwarp -s_srs "+proj=geo +datum=WGS84" -t_srs
"+proj=utm +zone=36 +datum=WGS84" mapgeo.tif maputm.tif ERROR 1: Translating
source or target SRS failed:</P>
<P>+proj=geo +datum=WGS84</P>
<P>Thanks in advance.</P>
<P>Best regards,</P>
