Scope: relation
Default severity: warning
Certainty: deterministic
Checks whether two rasters with the same CRS and resolution share the same pixel lattice. Integer-pixel origin offsets are aligned; fractional offsets are not.
PASS: grids share the pixel lattice.
FAIL: a fractional-pixel offset is present.
UNKNOWN: CRS/resolution is incompatible or rotation/skew prevents the
current deterministic test.
NOT_APPLICABLE: the relation is not between raster grids.
