yes; and use the TGRASS (Cc: Soeren, the author), framework. Also, raster stacks with time z should be of interest (Cc: Robert). > > But this should not hold back the release of spgrass7 in it's current > form. I suggest to rename this package to "grass", supporting the current grass release. Grass took 7 years to move 6 to 7; I discussed this with Markus last night, they might as well give up this crazy major version release cycle idea, with all kind of restrictions they impose on themselves. > > Cheers, > > Rainer > >> >> Roger >> >> >> On Wed, 11 Feb 2015, Veronica Andreo wrote: >> >>> Hi >>> >>> Since you are discussing the new spgrass for GRASS 7 (and since GRASS 7 >>> includes these great temporal modules), I was wondering if there's any >>> chance to include support for reading/writing spatio-temporal data sets. >>> >>> At present, there are two functions in spacetime package (read.tgrass and >>> write.tgrass) that allows reading and writing strds, but you need to export >>> it from GRASS first, do the R processing you need, and then, import it back >>> into GRASS.
