# Copy_from_Model - Takes average of model grids and stores them into
|
||
|
|
# current grid (in current edit area). For QPF and
|
||
|
|
# SnowAmt, does a sum rather than an average. For
|
||
|
|
# PoP does a Max rather than an average (to support
|
||
|
|
# floating PoP). User gets to choose the model and
|
||
|
|
# timeoffset. If TimeOffset is negative, it means
|
||
|
|
# get model data from earlier and put in this time -
|
||
|
|
# if TimeOffset is positive, it means get model
|
||
|
|
# data from later and put in this time.

# 03/26/2002 - Copy from Copy_from_Model routine
|
||
|
|
# 03/07/2003 - Added model time offset - so you can time-shift model
|
||
|
|
# data too. Also added stuff so that if your grid crosses
|
||
|
|
# more than one model PoP grid, it gets the Maximum PoP in
|
||
|
|
# the "floating PoP" sense.
