Rasterio's rio-sample command

can do any number of x, y pairs and only loads image data once. I think
it's a pretty good example of how to do
I have a list of longitudes and latitudes for which I extract the pixel
values using gdallocationinfo.exe one by one for each pairs of longitudes
and latitudes using for loop.
How I simultaneously get pixel values for all the list of longitudes and
latitudes?
My list is large, so I want faster

Dear Even Rouault:
Thanks for you quick response.
Unfortunately, I do not know how to pipe using python script.
I just know to use as follows:
for x, y in zip(lons, lats):
vals = subprocess.check_output([gdallocationinfo,

Dear Even Rouault:
Thanks for full Python script. I understood this.
However, since my lons and lats are thousands, it is taking days to extract
the values. So, my question is how can I sped up it. Is it possible to call
several tuples
