Hi,<br><br>Regarding the email listed below I was able to figure out issue "a" by having the RGB value separated by commas (-wo INIT_DEST=226,1,226) which now displays the "226 1 226" pixels for areas that don't have any data.
<br>I still can't figure out issue "b".<br><br>John Mitchell<br><br><div><span class="gmail_quote">On 10/23/07, <b class="gmail_sendername">John Mitchell</b> <<a href="mailto:mitchelljj98@gmail.com">mitchelljj98@gmail.com

<br>I have run the following command:<br>gdalwarp.exe -wo INIT_DEST="226 1 226" -rc -s_srs EPSG:4326 -t_srs EPSG:4326 inputgeotiff1.tif inputgeotiff2.tif outputgeotiff.tif<br><br>The resulting output geotiff has two issues:
<br>a.) The initial background value is an RGB of "226 226 226" instead of "226 1 226"<br>b.) The first geotiff image called inputgeotiff1.tif is not displayed and the area where it is supposed to be displayed has the initial background image instead. Note: The second input geotiff image is correctly displayed replacing the initial background image.
