4. CONCLUSIONS 
The authors have developed the spatial data acquisition tool 
under the following keywords; 1) When, 2) Where 3) What, 4) 
How many area for the specific land condition. At present some 
of unsolved problems still remained, but the method how to 
revise them, had almost been discussed. 
From this year, forest canopy crane is going to be constructed 
in Kuba National Park, Sarawak, Malaysia. We are planing that 
this developed system will be revising as the total observation 
system for forest ecosystem. All of obtained information should 
provide useful data for the other field of interested researchers. 
The moving observation is also applied for spatial expansion.
