示例1: RegionBboxLatLon
# 需要导入模块: from pycmbs.data import Data [as 别名]
# 或者: from pycmbs.data.Data import get_aoi_lat_lon [as 别名]
import matplotlib.pyplot as plt
# specify some region using bounding box
# here: 20deg W ... 30 DEG E, 40 DEG S ... 5 DEG N
r = RegionBboxLatLon(777, -20.0, 30.0, -40.0, 5.0, label="testregion") # 777 is just the ID value
# read some data as Data object
filename = download.get_sample_file(name="air", return_object=False)
air = Data(filename, "air", read=True)
# generate some plot BEFORE the masking
map_plot(air, title="before", use_basemap=True)
# now mask the data ...
air.get_aoi_lat_lon(r)
# generate some plot AFTER the masking
map_plot(air, title="after", use_basemap=True)
# ... o.k., so far so good, but the dataset "air" still contains data for the entire domain.
# even if it is masked it will eat some of your memory. You can see this by plotting the size of the matrix
print(air.shape)
# wouldn't it be nice to just remove everything which is not needed?
# Here you go ...
air.cut_bounding_box()
map_plot(air, title="after cutting", use_basemap=True)
# still looks the same, isn't it? No it isn't, look at the size!
print(air.shape)
