<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I have got a problem using the GDAL tool
gdalbuildvrt.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I would like to join two DEMs sampled on the same
grid which insist on the same </FONT></DIV>
<DIV><FONT size=2 face=Arial>geografical zone. </FONT></DIV>
<DIV><FONT size=2 face=Arial>The first DEM has got some NoDataValue holes and I
would like to feel them with the values in</FONT></DIV>
<DIV><FONT size=2 face=Arial>the second DEM. </FONT></DIV>
<DIV><FONT size=2 face=Arial>I ave used also the flag to ignore the projection
(-allow_projection_difference).</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>DEMs have the same raster size (xSize="10801"
ySize="7201"), the same data type ("Float32")</FONT></DIV>
<DIV><FONT size=2 face=Arial>and the same NoData Value
(-3.27670000000000E+04).</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>The GDAL tool goes in segmentation fault: any
ideas?</FONT></DIV>
