What I think you need to check your study area on the satellite image. I can suggest that you can place these satellite image and your shapefile of the study area in any GIS software, without forgetting to define a suitable common coordinate system for both files and to check if your study area overlaps the actual area of the satellite image. I hope you can understand what I suggest?
To give you a suggestion it will be useful if you give us some more information regarding the image type, size of your study area and general location. Best regards, Soledad
