global mapper

I'm using global mapper, and just want to know why do you need to georectify?

Geo rectification is actually required to assign geographical co-ordination to digital images.There is no geographical co-ordinates attached to images when scanned.But after geo-rectification,coordinates are attached to each pixel and the image now have geographic position.The data can align properly on pixel image and this can be overlaid to create map.
