[gdal-dev] gdallocationinfo.exe multiple access

[Yuta Sato]

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 retrieval.
I am using python and outputting the pixel values into text file.
Is it possible?
