Here are 3 examples, which are extremely 
large and beyond the custom size while 
without any splices, only under the control of 
five rectifying points. (Area: 60cmx70Cm, 
80cmx180cm, 60cmx200cm) They are drawn 
by the unit of exploration level A. The 
operation is open and without any 
modification.

2 1:1000 area chart, made from the map over 
80cmx180cm in the way of digitized mapping 
and its rectified one. Please pay attention to 
the joints, which are smooth and nature.

60cmx200cm in the way of digitized mapping 
and its rectified one. 
  
6. Conclusion 
As what here mention above the know-how of 
five control points rectifying digital image can 
be used easily, effectively and with high 
accurately. The image map size is extremely 
large and beyond the custom size while 
without splices is useful. Now for city using 
GIS-THE ROAD AHEAD and cadastre 
catalyst to growth can also use the state 
method to practice and with low cost.
