The following images show the steps taken to georeference the Old Map (UTM12N) to the Ikonos Image (US27TM12N). 
 


This is the topographic map which was used for georeferencing the Old Map.  The scale is 1:50,000 (UTM12N) and it dates back to 1984. 


 

The georeferenced old map can be seen on the right side.  This intermediate step was necessary to project it to the Ikonos image for the subsequent comparison.



The Old Map projected to the Ikonos projection (US27TM12). The classified version is used for the Comparison.
