3. CONCLUSIONS AND FUTURE WORKS 
3.1 Conclusions 
In the future, various types of spatial data as well as basic map 
information will be developed in accordance with JPGIS. 
Because the JPGIS specifications do not correspond to a 
specific form of data, we need to have a flexible data creation 
methodology to produce various JPGIS-based spatial data. 
It is difficult to create such spatial data using only the 
conventional technology and knowledge needed to create 
topographic map data. It is desirable to configure a production 
system that integrates not only software but also a method of 
improving workers’ knowledge and a method of preparing the 
documentation including easy-to-understand work instructions. 
For this purpose, the spatial data to meet the required 
specifications could not be created merely by purchasing and 
use of advanced GIS software. In order to achieve the purpose, 
what is required is the development of a production system that 
supports workers, software and documentation in an integrated 
way. 
3.2 Future Works 
One of the existing problems is that it takes a great deal of labor 
to build a working environment in which the burden on workers 
can be reduced to the same level of total working hours for the 
conventional method. Building such environment requires 
managers who understand all the product specifications, spatial 
data structures and the workflow of the actual work. It is also 
necessary to train managerial personnel for this work. Therefore, 
it is necessary to develop a production system in which the 
building of the working environment is as automated as 
possible. In addition, it is necessary to build a production 
system that is not only efficient, but in which consideration has 
been given to the education and training of engineers.
