What is the georeferencing in GIS?
Georeferencing is the name given to the process of transforming a scanned map or aerial photograph so it appears “in place” in GIS. By associating features on the scanned image with real world x and y coordinates, the software can progressively warp the image so it fits to other spatial datasets.

How does a reprojection in ENVI work?
ENVI performs a reprojection by first converting the input dataset’s map extents into the selected output coordinate system to determine the output map extents.
How can I use a Roi in ENVI?
You can use ROIs for processing in some ENVI tools, such as to extract statistics for classification. To create and manage ROIs, click the Region of Interest (ROI) Tool button on the toolbar. When you define an ROI, you specify the pixels of an image that will be in or out of the ROI.
Are there any issues with ENVI classic geospatial?
