Sample pixels from a dataset
- Parameters
dataset (rasterio Dataset) – Opened in “r” mode.
xy (iterable) –
Pairs of x, y coordinates in the dataset’s reference system.
Note: Sorting coordinates can often yield better performance. A sort_xy function is provided in this module for convenience.
indexes (int or list of int) – Indexes of dataset bands to sample.
masked (bool, default: False) – Whether to mask samples that fall outside the extent of the dataset.
- Yields
array – A array of length equal to the number of specified indexes containing the dataset values for the bands corresponding to those indexes.
