[GRASS-user] i.landsat.toar comments have only 0 value

Hi all, I just ran i.landsat.toar to get the radiance values for a TM5 image and I noticed that the comments in the output metadata (from r.info) have some problem. 1) I asked for radiance output but the comments says the image is reflectance. Image values are consistent with radiance values so I

Got the job done, thanks for all the pointers. Took location info from the readme file included in download (which is different to the online help). Used a lat-long on wgs84 projection. Imported via r.in.bin, and again included the details from readme file in bounds tab. Strikes me usgs made

I'm not sure how to pull it off now given the current structure, but IMHO, the ideal organization would be to have 1 sqlite DB for each vector file--so a single DB for all layers of a single vector. That makes vector files portable. I'm not sure if joins across layer tables are needed because
