Andreas Braun

This is quite well discusses here: https://gis.stackexchange.com/questions/221292/retrieve-pixel-value-with-geographic-coordinate-as-input-with-gdal

Leônidas Luiz Volcato Descovi Filho

Dear Dr Elango

Very well answered by Dr Braun.

In addition, if you do not know and want to know a graphic software to perform this task, I strongly recommend QGIS. See more at qgis.org.

Best regards.

Avinash Gaykar

Hello Elango

Don't Know much about the Python Language. But If you have point locations in the form of shape file, you can easily extract the raster values of that location using ArcGIS with Tool Name ' Extract Values to points ' .
