Cov Wish List
From Spatial Data on the Web Working Group
- all axes should be treated equal, with no particular preference; implementations should be free to choose suitable internal representations, such as partitioning
- into time slices (ie, thickness 1 along time, anything along Lat/Long) - suitable for retrieval of image layers
- into "time rods" (ie, extent 1 along Lat/Long, arbitrary length along time) - suitable for timeseries analysis
- mixtures and variations of both
- a coverage should have one Coordinate Reference System (CRS) associated which specifies the meaning of space/time coordinates
- a coverage should follow the OGC Coverage Implementation Model (CIM, formerly known as GMLCOV; OGC 09-146r2) which is about to become ISO standard, too
- a coverage should be uniformly represented, independent from any particular format encoding (such as RDF, GML, JSON, NetCDF, GeoTIFF)
