Microsoft Planetary Computer Pro 包含一個可用來可視化某些 NetCDF 資產的切片工具。
檢查 NetCDF 視覺效果
並非所有可以內嵌到Microsoft行星計算機的 NetCDF 數據集都與行星計算機專業版的視覺效果磚相容。 數據集必須具有 X 和 Y 軸、緯度和經度座標,以及要可視化的空間維度和界限。 例如,緯度和經度是變數,但不是座標的資料集,與行星計算機專業版的磚器不相容。
嘗試將 NetCDF 資料集可視化之前,您可以使用下列項目來檢查它是否符合需求。
安裝所需的依賴項
pip install xarray[io] rioxarray cf_xarray
執行下列函式:
import xarray as xr import cf_xarray import rioxarray def is_dataset_visualizable(ds: xr.Dataset): """ Test if the dataset is compatible with the Planetary Computer tiler API. Raises an informative error if the dataset is not compatible. """ if not ds.cf.axes: raise ValueError("Dataset does not have CF axes") if not ds.cf.coordinates: raise ValueError("Dataset does not have CF coordinates") if not {"X", "Y"} <= ds.cf.axes.keys(): raise ValueError(f"Dataset must have CF X and Y axes, found: {ds.cf.axes.keys()}") if not {"latitude", "longitude"} <= ds.cf.coordinates.keys(): raise ValueError("Dataset must have CF latitude and longitude coordinates, " f"actual: {ds.cf.coordinates.keys()}") if ds.rio.x_dim is None or ds.rio.y_dim is None: raise ValueError("Dataset does not have rioxarray spatial dimensions") if ds.rio.bounds() is None: raise ValueError("Dataset does not have rioxarray bounds") left, bottom, right, top = ds.rio.bounds() if left < -180 or right > 180 or bottom < -90 or top > 90: raise ValueError("Dataset bounds are not valid; they must be within [-180, 180] and [-90, 90]") if ds.rio.resolution() is None: raise ValueError("Dataset does not have rioxarray resolution") if ds.rio.transform() is None: raise ValueError("Dataset does not have rioxarray transform") print("✅ Dataset is compatible with the Planetary Computer tiler API.")
