GDB files containing latin-1 characters cannot be opened
We often receive GDB files from contractors that contain data descriptions such as µT, but the descriptions are encoded using latin1. As a result, the µ character is encoded as 0xB5 rather than 0xC2 0xB5 as it would be in UTF-8.
Since Python strings are Unicode and gxpy loads strings in the default fashion, we end up with errors like this:
'utf-8' codec can't decode byte 0xb5 in position 0: invalid start byte
Handling other character encodings (or perhaps only latin1 if that's what GDB uses) would allow us to open these files with gxpy.
@mplough-kobold Can you share the sample gdb with the ISO/IEC 8859-1 encoding?
@serban-seeq From SIGÉOM, see https://gq.mines.gouv.qc.ca/documents/EXAMINE/GM67278/. In GM67278_1_CD1.ZIP there exists a file called Deborah_Lake.gdb. The file is too large to upload here but the source is publicly available.
@mplough-kobold Can you say in which step you're seeing this error? I'm being able to Load the Debora_lake.gb and print the unit of the channel tauBx10_30, which is µT, by using the following commands:
with gxdb.Geosoft_gdb.open('Deborah_Lake') as gdb:
unit = gxdb.Channel(gdb, 'tauBx10_30').unit_of_measure
print ('Unit - {} '.format(unit))
Haven't received sample in order to reproduce. can reopen in the future but closing for now
