As Zoltan suggested, a .vrt is a good approach, but you will want overviews
also so that you can zoom out. You can create overviews (aka pyramids) of
.vrt files.
Personally, I'd suggest creating one, or a few, big GeoTIFFs with internal
or external overviews. I have a 4,400 sq mile (1,140,000
Searching I can't find anything on the topic (or I don't know what to search
for . . .), but when you are tracing around something and creating a new
polygon (or line) and you click and place a vertex in the wrong spot is there
an way to IMMEDIATELY do some kind of UNDO to remove either the
Hi Jason,
You just need to create a VRT.
The vrt is just that: a virtual raster table.
Fiddle with the options and notice that you can mix rasters that have differing
projection.
Test out on maybe a 100 or so Raster files and when you get the feel for it,
dump the lot in. I've had >5000 files

I am trying to add imagery in qGIS. In ArcMap, I had to create a Mosaic
Dataset, then a Raster Catalog. It tooks days to create due to the large
files and quantity of files. I have 6 inch imagery of a county in a
folder. The GeoTIFFs are about 308GB in size and approx 6,610 files (TIF
and
Hi Johannes,
Thanks for getting back to me. In general we would use the same value for each
band, so 256 or -. We only work, where possible with GeoTIFF, so the
Internal Mask idea is a nice one I hadn’t thought of. Also the use of an ALPHA
channel, might be an option.
I could be wrong, but
Grazie mille a tutti!
prego Rossella di prendere nota, così costituiamo un team.
Saluti.

Hey Richard,
do you have different NODATA pixels between the three bands (R, G, B) or
is it the same? If there are no differences then you can use an
additional channel as mask. I would suggest you store your imagery in
GeoTIFF with an "internal mask". Even posted a nice example of this in
