Using 3D Computer Graphic
4. Development Software for Education
With motive, the authors have been concentrated developing software. The information for a certain point can be easily obtained by pointing the direction and position on globe surface. This is the conception for this software and the detailed information for this trial manufacture software are as follows:
Fig. 1 shows world map and globe and illustration of city by the software of city by the software.

Figure 1 World map, globe and illustration of city
The illustration of world map can be change in response to uses by using land-use data, land-shadow data and satellite image which were prepared.
Globe surface change in response to change the illustration of world map because globe is connected with world map. By using this connected function, image information can be also obtained excepting character.
The software have another function. For example, more detailed by using a function of expansion and reduction. The distance between two points can be also obtained by opining two points with mouse.
Globe showed in Fig.2 can be turned to all direction by using mouse. This function be a help to understand the position relationship between
the plane the surface of the globe.

Figure 2 Globe
This software also have a function which able to display the bird's view map show in Fig.3.

Figure 3 Bird's-eye view
Similarly, this function be a helpful to user because the user can obtain three dimensional information.
Fig. 4 shows an example for the NAGANO Prefecture in Japan. It's possible for these small area to show much data than word and possible to overlap the additional data such as

Figure 4 NAGANO Prefecture
Shown in Fig. 5 The various community feature can be obtained as a visually by devising the combination of data.

Figure 5 Overlap the additional data
In order to obtain more detailed information of community, geographic information menu such as shown in Fig. 6 were prepared in this software. For example, when it is needed to obtain more detailed information for one the mountain in this area, explanation and images such as shown in Fig. 7 can be obtained with easy by using menu.

Figure 6 Geographic information menu

Figure 7 Picture of mountain
The above discussions show only some of example for this software, it is concluded that this software, it is concluded that this software is a useful tool for computer education.
5. Conclusion
In this paper, trial software for computer education were discussed. The performance of this software did exactly what was expected. There are, however, some issues which is need to resolved before this software may become operation. These problems include, addition data, additional functions and efficient renewal of data by utilizing inter net system.
However, it is concluded that these software are become useful tool for geographic education in elementary, junior and high school.
