    Hi,
    I want to extract the pixel value of the vector points from a stack of raster and secondly I want to establish a rectangle around that point and extract the value in that rectangle. How can I do that?
    Thanks in advance.

    Have you tried ENVIs cursor value tool? See Display Tools: https://www.harrisgeospatial.com/docs/DisplayTools.html

    Does this tool provide you with what you need? If not, can you elaborate on what data you have loaded into ENVI, and the format it is in?

    In addition, it seems you are looking to build an ROI around a point. Have you tried using the ROI tool within the ENVI menu bar to extract values within a drawn region of interest? Here are some handy URLs:
