gdalwarp progress stops at 90percent

[david]

When running the gdalwarp process on a subfolder of imagery (GeoTIFF input, GeoTIFF output) or elevation (DT1 input, GeoTIFF output), several inputs never reach 100% completion:

0…10…20…30…40…50…60…70…80…90…100 -Done.

They stop at 90%:

0…10…20…30…40…50…60…70…80…90…

Even after repeated attempts. No warnings indicated. I can still open the output in a viewer. Seems ok.

FW suggested "...expect this is a peculiarity of rounding the progress values in gdalwarp."

This is the command I am using for imagery:

for /R J:\SourceData?\Imagery\ %%F IN (*.tif) DO "C:\FWTools1.3.4\bin\gdalwarp" -t_srs "+proj=UTM +zone=38 +datum=WGS84" -multi -rcs -of GTiff %%F K:\15m_Reprojected\%%~nF.tif

This is the command I am using for DTED:

for /R J:\SourceData?\DTED\ %%F IN (*.dt1) DO "C:\FWTools1.3.4\bin\gdalwarp" -t_srs "+proj=UTM +zone=38 +datum=WGS84" -multi -rcs -of GTiff %%F K:\DTED_Reprojected\%%~nF.tif

You will note I am using FWTools1.3.4 (for Win 32) on WinXP desktop PC with 2GB RAM.

I have confirmed this, though it only seems to happen on windows. I guess this confirms it is a subtle issue with floating point rounding. The fix is in trunk only (r11737). It should appear in the next FWTools release.
