<br>
I have a set of rasters which I warped to epsg:3857 projection using gdalwarp.<br>
During the reprojecting the new </span>raster had been rotated by small angle.<br>
After that I created a tileindex shape file using gdaltindex and configured layer:<br>
<span style="font-size:7.5pt">LAYER<br>
NAME "myname"<br>
TILEINDEX "tilindex.shp"<br>
TYPE RASTER<br>
OFFSITE 0 0 0 <br>
END</span><br>
<br>
On the result map I see the gaps between raster files. Please look at images: <br>

<br>
Maybe some of you recognize the problem. There is the problem with one pixel gap between raster files in tileindex layer.<br>
<br>
Maybe there is a option in gdalwarp command to extend the new image by making it 1 pixel widther? Maybe something like resampling method or algorithm?<br>
<br>
I googled similar problem in goeserver:<br>

<br>
Could you please point me to the right solution?<br>
<br>
Thanks in advance<br>
