我正在按照Pyresample 示例绘制 Sentinel-3 场景和海岸线。但是,似乎pyresample.kd_tree.resample_nearest
并pyresample.save_quicklook
期望将 2D 数组作为数据,而不是我试图绘制的 3D(3 波段)Sentinel 场景:
<xarray.DataArray 'reshape-fb54fb4cbc6c65d43122d7b5e1078a83' (bands: 3, y: 352, x: 507)>
dask.array<reshape, shape=(3, 352, 507), dtype=float64, chunksize=(3, 352, 507), chunktype=numpy.ndarray>
Coordinates:
* x (x) float64 -7.601e+04 -7.571e+04 ... 7.571e+04 7.601e+04
* y (y) float64 5.227e+04 5.197e+04 5.167e+04 ... -5.279e+04 -5.309e+04
* bands (bands) <U1 'R' 'G' 'B'

伪代码和错误是:
lons, lats = scn_aoi[composite].area.get_lonlats()
composite_data = scn_aoi[composite].data.compute()
swath_def = pyresample.SwathDefinition(lons, lats)
roi = resolution - (resolution * 0.35)
# Below gives ValueError -> 'Mismatch between geometry and dataset'
composite_swath = (pyresample.kd_tree
.resample_nearest(swath_def, composite_data, aoi_def,
radius_of_influence=roi,
fill_value=None))
如何绘制这些数据?
