Learn to subset an image using a Shapefile by using an existing vector polygon to define the output boundary.

Dear Ms Annoah,


Just as shown in your video,   I want to select the AOI polygon over the ratser image by clicking the AOI in the viewer to select it so that I am able to maybe tweak around with the border lines nad make it more visible for me. Then later save teh created AOI polygon somewhere so I can use it for a later use just as you have demonstrated.


But unfortunately after removing the shape file from the TOC pane, and then clicking the area where the AOI polygon was displayed , I am unable to select the AOI in teh viewer just as it is shown in the short video turorial. I do not know why?


I have been on this simple procedure since yesterday.


Out of frustartion, I used Arc Map to subset my Landsat image with a local government area boundary file by using the Extract by mask. I successfully got a sub setted AOI polygon of my area


But now I am having difficulties in importing the sub setted AOI from Arc into ERDAS
