• The read_array method can read the whole band, read a window using top_left_corner and width and height, or a polygon geodataframe.
• The extract method extracts the values at the location of point geometry, the extract now reads the entire dataset to extract the values and used array slicing to access the array, which is not efficient if the dataset is big.
• the extract method could be merged into the read_array method where a new parameter can be added points and the values can be extracted using the same way in the extract method now if the dataset is small, In case that the dataset is big the method can locate the points in the array and then use the src.ReadAsArray(xoff, yoff, xwindow, ywindow) to read the values while the dataset is on desk.
