2. Go to Raster - Georeferencer - Georeferencer.
3. Add unreferenced map to window.
4. Go to settings - Assign projection information and output path and file.
5. Go to Add points - Zoom to level and add point and assign long / lat for the all added points.
6. Save ground control points.
7. Run - start georeferencer.
8. Once georeferencer is successfully completed, close georeferencer and add the referenced map to QGIS window by add raster layer. It may used for further wotk.

Dear Moumita, Your target resolution may be low. try to increase it in the transformation settings. Otherwise don't opt that. leave as it is. It may be fine. Try it. otherwise i will look into it. Thank you for the comment.

You can add toposheets or maps which are in image formats like jpg, jpeg, tiff, geotiff or .img etc into QGIS. Thank you for comment. Please follow the channel for updates.

What is the purpose of Filter?
I dont know what to put there
Thank you for comment. Filter option is only to search your required projection information to assign. As we need to assign any of the projection systems, you can type the projection information like wgs or utm or any other specific.
