4.3 Eros-Al vs SPOT-5 HRG 
A final test involving multi-sensor with similar geometric 
resolution was performed using the 2.6 m Eros-Al image and 
the 2.5 m SPOT-5 HRG image over the test area. 
As in the previous examples, homologous points have been 
automatically extracted with the GEOREF software from both This w 
images, and on the basis of the computed CPs a 2D affine founde 
transformation has been estimated for image data fusion. Figure (COFII

The development of GEOREF SW has been carried out for 
research and technology transfer purposes. All people, institutes 
and companies having the same interests are encouraged to 
contact the authors which will provide to send a fully Refere 
operational demo-license. All GEOREF's users are invited to Forma 
share results of their activities and to cooperate to the Wiley,
