- When using rioxarray.open_rasterio() with band_as_variable=True and then calling .to_array().sel(variable='band_1', drop=True), the resulting dask array has a different chunk structure than arrays created directly. The crosstab function failed because it pairs dask blocks positionally via to_delayed().ravel(), which requires aligned chunks. To fix this:
- added documentation about float32 handling
…hen calling .to_array().sel(variable='band_1', drop=True), the resulting dask array has a different chunk structure than arrays created directly. The crosstab function failed because it pairs dask blocks positionally via to_delayed().ravel(), which requires aligned chunks. To fix this: Added chunk validation for 2D inputs in crosstab, using the existing validate_arrays function (which is already used by zonal_stats). This function: 1. Validates that shapes match 2. Automatically rechunks values to match zones chunk structure when they differ
