2.2.4 Function to Allow Operators to Work without 
Knowing New Specifications 
Workers can operate the system paying little attention to the 
differences from conventional data models. As shown in Figure 
5, the planimetrie features for which figures only had been laid 
out in the conventional method can be laid out automatically 
together with the “thematic attributes” and “associations”, al 
lowing workers to create new data models using operations 
similar to the conventional method.

figures 
2.2.5 Techniques to Standardize Work Procedures 
The differences in the working methods used by workers may 
result in differences in quality and efficiency. The new system 
leads workers to operate in the same way. Figure 6 shows the 
working procedure to allow workers to operate the spatial data 
creation system in the order in which the work processes are 
numbered.

2.2.6 Functions to Enable Reference to Product/Work 
Specifications during Work 
Workers have to check product or work specifications often, 
and may overlook some detailed specifications or instructions. 
To prevent such mistakes, the new system allows those specifi 
cations to be referenced within the input system, as shown in 
Figure 7. As a result, workers can readily find unclear points in 
the work procedures, reduce mistakes and shorten the time 
taken to check the specifications.

2.2.7 Functions for More Efficient Quality Evaluation 
In quality evaluation, logical consistency can be checked 
through program processing, but other quality elements are of 
ten inspected by visual check. As visual checks often result in 
high cost, involves a higher cost, the position-related elements 
such as positional accuracy and thematic accuracy, and those 
elements that can be compared by combinations of attribute 
values, are evaluated by program processing. The function to 
obtain positional accuracy for each line element by spatial cal 
culation has been developed as shown in Figure 8. 
2.3 Operational Advantages of the New System 
The operation of the production system has facilitated the 
creation of spatial data in compliance with JPGIS. This method 
is more advantageous than the conventional method in 
structuring higher-specified spatial data to be as simple as 
possible and easier to create. 
The new system is intended to have the effect of arousing no 
resistance in skilled workers against the creation of spatial data 
with a new structure, and of preventing mistakes caused by 
inexperienced workers due to their insufficient understanding of 
specifications. This dual effect makes it possible to create 
spatial data under complex specifications at a cost that is not so 
different from the cost of creating topographic maps using the 
conventional method.
