Markus, in my case resolution is  RES=0:00:01, should I use decimal degrees
(RES=0.000278 , not sure it is correct) ?

My steps are the following:

# RES=0:00:01
RES=0.000278
BIGTIFF="-co BIGTIFF=YES"
# GDAL cache in megabytes
CACHE="--config GDAL_CACHEMAX 8000 -wm 8000"
# Select from the complete ASTER coverage, the limits for Europe, and put
it in a LIST:
LIST="ogr2ogr -f index_dem.shp -spat -11.0001389 33.9998611 43.0001389
72.0001389 "
gdalwarp $CACHE $BIGTIFF -srcnodata * -dstnodata * -r bilinear -tr $RES
$RES $LIST mosaik_$RES.tif

But I get:

[leomarg at d01ri1002912 Dem_lzw]$ gdalwarp $CACHE $BIGTIFF -srcnodata *
-dstnodata * -r bilinear -tr $RES $RES $LIST mosaik_$RES.tif

Usage: gdalwarp [--help-general] [--formats]
    [-s_srs srs_def] [-t_srs srs_def] [-to "NAME=VALUE"]
    [-order n] [-tps] [-rpc] [-geoloc] [-et err_threshold]
    [-te xmin ymin xmax ymax] [-tr xres yres] [-tap] [-ts width height]
    [-wo "NAME=VALUE"] [-ot Byte/Int16/...] [-wt Byte/Int16]
    [-srcnodata "value [value...]"] [-dstnodata "value [value...]"]
-dstalpha
    [-r resampling_method] [-wm memory_in_mb] [-multi] [-q]
    [-cutline datasource] [-cl layer] [-cwhere expression]
    [-csql statement] [-cblend dist_in_pixels]
    [-of format] [-co "NAME=VALUE"]* [-overwrite]
    srcfile* dstfile

Available resampling methods:
    near (default), bilinear, cubic, cubicspline, lanczos.


where am I wrong?

TIA
