有组地形数据,
Variables:
X
Size: 4320x1
Dimensions: X
Datatype: single
Attributes:
pointwidth = 0.0833
gridtype = 1
units = 'degree_east'
Y
Size: 2160x1
Dimensions: Y
Datatype: single
Attributes:
bounds = 'Y'
pointwidth = 0.0833
gridtype = 0
units = 'degree_north'
elev
Size: 4320x2160
Dimensions: X,Y
Datatype: int16
Attributes:
units = 'm'
long_name = 'elevation/bathymetry'
scale_max = 7.96e+03
ncolor = 253
colormap = '[0 1973790 4026644 [4026644 28] 9125192 [9125192 28] [15736992 15] [11829830 15] [16711680 15] [16760576 29] [16776960 14] 65280 3329434 2330219 [9234160 3] 65535 55295 755384 [755384 4] 9408444 [9408444 3] 6053069 [6053069 4] 1262987 [1262987 3] [2970272 8] [17919 15] 7504122 [7504122 14] 13353215 [13353215 14] 12903679 [12903679 14] 14480885 [14480885 14] 16777215 [16777215 13] 12632256]'
colorscalename = 'topographycolorscale'
CS = -9.96e+03
scale_min = -9.96e+03
maxncolor = 253
CE = 7.96e+03
如果想取X(1441:1597)Y(709:901)这一块的地形作图,那个经纬度和高分别怎么定义?还是能直接读出来?本人菜鸟,望指点
