[Numpy-discussion] taking a 2D uneven surface slice

2013-04-16 Thread Bryan Woods
I'm trying to do something that at first glance I think should be simple but I can't quite figure out how to do it. The problem is as follows: I have a 3D grid Values[Nx, Ny, Nz] I want to slice Values at a 2D surface in the Z dimension specified by Z_index[Nx, Ny] and return a 2D slice[Nx, N

Hello, I am loading in data from the GRIB2 files using PyNIO. Once I load them into numpy arrays I am left with a halo of values near the array boundaries that appear to be empty. When I print them or use them in conditional statements I see values of '--'. I'd like to turn these values into

I have spent over an hour now trying to figure out what I thought would be a really basic conditional array assignment. I am very new to python and am in need of help. I have a 2D integer array of land cover classes and a 1D array with a roughness value for each class. I am trying to create a
