Hi Michael,<br>
<br>
I have 4 images with approx 30% overlap in each axis (north/east). I
would like to mosaic the images to get a single big images covering
the full area.<br>
<br>
I hope that the images are nicely blended into each other so I don't
see the the seam/border of the original images - I was hoping to get
something similar to "enblend/enfuse"
(<a href="http://enblend.sourceforge.net" target="_blank">http://enblend.sourceforge.net</a>). I don't think that enblend/enfuse
keeps my georefencing - or does it?<span class="HOEnZb"><font color="#888888"><br>

<div>Hi Andreas,<br>
<br>
Do you mean that you want to effectively create a stack of
rasters (i.e., multi-band raster)? If not, we might need some
more details.<br>
<br>
If so, the Raster Merge operation (using gdal_warp) should
work - go to Raster -> Miscellaneous -> Merge, and check
the box for "Layer Stack" (<a href="http://www.gdal.org/gdal_merge.html" target="_blank">http://www.gdal.org/gdal_merge.html</a>).<br>
<br>
</div>
<div>You can also do that in SAGA via Import/Export ->
GDAL/OGR -> GDAL: Export Raster, and add multiple grids,
though this is a bit more constrained and I think needs to
have all layers in the same Resolution.<br>
<br>
</div>
<div>This is also do-able in R using the Raster package, look
into "brick", "stack", and "writeRaster"<br>
<br>
</div>
<div>hope that helps,<br>

<br>
I georeferenced four overlapping aerial images - with
QGIS/GDAL and the thin plate spline method. Now I want to
mosaick/blend the overlapping images. Are there any good
FOSSGIS tools available that support mosaicking with
blending? Perhaps with SAGA/GRASS/OTB? Any recommendations?<br>
<br>
Thanks for any pointers/tutorials.<br>
