Figure 2. Location map of field and the distribution of GPS continuous observation stations 
of GEONET used for reference networks in this experiment 
(The distance from field to the nearest reference station: 4.4 km in the smaller network and 22.9 km in the larger network) 
  
Fix the “Geodetic Coordinates 2000” to all reference stations 
  
Surveying by using the different coordinates 
Fix the “Recent Analytic Coordinates” to all reference stations 
  
The larger Network (Sakai, Inagawa, Ootsu2) 
Surveying by using the different REF. networks Witltan average basoling longth of 33 bm
