Description (last modified by martins)

In dem2pts there is a change to an iterative process which takes an order of magnitude longer to complete, starting from line 241:

if upper_index == lower_index + newcols:

# Seems to be an error with the windows version of # Netcdf. The following gave errors #points[lower_index:upper_index, :] = tpoints #elevation[lower_index:upper_index] = telev # so used the following for index in range(newcols):

points[index+lower_index, :] = tpoints[index,:] elevation[index+lower_index] = telev[index]

Not sure what the netcdf problem is but maybe this is not the way to deal with it?

  • Resolution set to fixed
  • Status changed from new to closed

Changed to the faster code. if faster code fail (which it does for some strange reason on windows) it falls back to slow code.
