comment Help obtaining nodata information for ASTER datasets
That is true for one dataset that has a nodata field of -32767. This one has invalid data that returns -1 - which is unlikely to be the minimum. I don't want to change the content of the tiff images - I would like to write a nodata tag, but I can't be sure that -1 is really an invalid value unless I can find some other way (other than a tag, which is missing) to give me information about invalid values. I have searched the web - and all I found is that for that type of DEMs there seems to be a -1 offset... Not sure if this info helps me though.
