-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi
I am creating a huge amount of raster layers during my simulations, and I would like to archive then to enable further analysis. At the moment I am leaving them in the grass database and compress the whole mapset into a tar.gz file. But this is rather cumbersome, if I want to extract some selected layers and analyse them further (my analysis is done in R). Therefore I would like to export the created layers while the simulation is running and to delete them from the grass database. My question: what is the best format for this? It should : - - contain all the information contained in the raster layer in the grass mapset - - be readable by at least gdal - - be preferably compressed (but I can compress them after export) At the moment I am using for a similar purpose the esri asc grid, but I am somehow critical about the fact that it uses a text representation of my data with limited decimals, therefore probably loosing information compared with the grass file. Are Binary fiels a better option (in the manual it states "Exports", not "converts" as in the esri ascii grid) and can I read them from R or gdal? Any ideas welcome, Rainer - -- Rainer M.
