Subject: Re: [GRASSLIST:8983] r.terraflow: wrong data type
Hi Hamish,
I looked at the code. Internally Terraflow uses the same type for
elevation and filled-elevation streams. The truncation to CELL
happens only we convert from the terraflow streams into a GRASS grid.
in main.cc
stream2_CELL(filledstr, nrows, ncols, opt->filled_grid);
should be
stream2_FCELL(filledstr, nrows, ncols, opt->filled_grid);
or more precisely, it should be templated on the elevation type.
Technically this should be corrected, and I'll look into it . Unless
somebody else volunteers in the meantime..
