#618: rfe: r.md5sum or equivalent --------------------------+------------------------------------------------- Reporter: hamish | Owner: [email protected] Type: enhancement | Status: new Priority: normal | Milestone: 6.5.0 Component: Raster | Version: svn-trunk Resolution: | Keywords: testsuite, r.univar, md5sum Platform: All | Cpu: All --------------------------+------------------------------------------------- Comment (by glynn):
Replying to [ticket:618 hamish]: > It would be helpful for comparing maps if there was some r.md5sum module or equivalent. What '''exactly''' should this module compute? MD5 and other hash algorithms operate on a sequence of bytes, so you need to decide exactly how to serialise the data. Should it operate upon the raw map data, or after reclassing, MASKing, and clipping and resampling according to the current region? How are nulls represented? Are numeric values serialised big-endian, little-endian, or in the host's native format? Or as decimal values in ASCII? -- Ticket URL: <https://trac.osgeo.org/grass/ticket/618#comment:3> GRASS GIS <http://grass.osgeo.org>
