# GDAL commands to produced fused DEMs in the vicinity of the 60N Canada
2
# boundary, using several "boundary-corrected" variants as well as the
3
# original uncorrected DEMs. Note that the multiresolution spline is not
4
# included here, because the associated fused layer is already produced
5
# in its entirety during that process.
