Old SpatialReference to new VertexGrid

[JoshuaRendon]

I use version 3.9.3. I recently received an old script that uses mf2005. I ran the code to understand what it does, but the spatial reference is defined with a deprecated SpatialReference. I want to know which module I should use. This is the script:

model_epsg = 3116
xll, yll =894454, 1458685 # origin of the model (lower left corner)
# row and column spacings
# (note that delc is column spacings along a row; delr the row spacings along a column)
dec = np.ones(nrow, dtype=float) * delr
der = np.ones(ncol, dtype=float) * delr

mf1.sr = SpatialReference(delr=der, delc=dec, xll=xll, yll=yll, epsg=model_epsg)

print(mf1.sr)

mf1.modelgrid.set_coord_info(xoff=xll, yoff=yll, angrot=0,epsg=3116)
mf1.dis.start_datetime = '7/4/2000'

@JoshuaRendon,
The modelgrid object is the replacement to the old SpatialReference class. The Grid classes support structured, vertex, and unstructured grid representations. You can get a StructuredGrid object from your code by simply calling:

mf1.modelgrid.set_coord_info(xoff=xll, yoff=yll, angrot=0, epsg=3116)
grid = mf1.modelgrid

You can also get a modeltime object, which has fairly robust time support, by calling:

modeltime = mf1.modeltime
modeltime.start_datetime ="7/4/2000"
