This document outlines the steps for georeferencing a satellite image using a topo sheet in ArcMap. It includes instructions on how to remove projections, identify control points, and ensure proper alignment between the maps. Finally, it covers how to save the georeferenced image.

1. Image to Image Georeferencing – from topo sheet to satellite image
Step 1:
Openbothsatellite imagefiletobe georeferencedandthe alreadygeoreferencedfileinArcMap.
Remove projectionsonthe files.Keepco-ordinatesasGCS-WGS1984 (GeographicCoordinate system)
Make sure that the file tobe georeferencedisshowing withinthe georeferencingtool barwindow.
Step 2:
Identifysimilarpoints/features inboththe maps- satellite image andgeoreferencedtoposheet.
Step 3:
To georeference apointonthe satellite image:
select‘addcontrol point’and singleclickonthe pointinthe satellite image andthe similararea
intoposheet.(Donotdouble clickonrasterimage)

2. Repeatthisstepandadd at leastfourcontrol points.The pointschosenshouldbe evenlydistributed
across the map for betteralignmentof bothmaps.
The topo sheetwill be showingup underthe satellite image accordingtothe pointsgiven (highlightedin
blue circle in image).
Step 4:
To see the alignmentof the satellite mapwiththe toposheet,rightclickonthe tool bar above,select
‘Effects’.Inthe Effectstoolbar,select‘Swipe down’andclickanddrag downfromthe arrow on the map
to see the map below.
Step 5:
Save the georeferencedsatellite imageusing‘Rectify’inthe georeferencingtoolbar.
