Conclusion and Suggestion 
The result of this study demonstrated the improvement on the mápping and 
data input process. The average time saving and the enhancement of accuracy are 
the major outcome fromi this study since the GIS process reduce the possibility of 
human error and increase the exactness. If the cost of database building can be 
ignore, this GIS technique showed an economic incentive for land appraisal market. 
First, in this.study we apply GIS techniques to land appraisal. As indicated, 
it can automatically determine and measure the distance to the selected target. 
Consequently, it increases the efficiency and convenience in land appraisal. 
Second, it can further analyze the distribution of public facilities and transportation 
system reducing the demand of manpower. Third, it can provide a more accurate 
distance measure and reduce the possibility of human errór. 
Noting that there are many types of public facilities with different degrees of 
importance. Therefore, one may set different weights for the various public 
facilities in order to reflect the real importance. Next, in this study only the 
distance to CBD is considered. Since the function of the neighborhood 
commercial centers is increasing, it may have some impacts on land price. One 
may need to include the different layers of commercial centers into consideration in 
order to get a better estimate of land price.
