Recently, various geographic information systems have been used based on spatial information of geographic information systems. Accordingly, it is essential to produce a large-scale map as a small-scale map for various uses of spatial information. However, maps currently being produced have inconsistencies between data due to production timing and limitations in expression, and productivity efficiency is greatly reduced due to errors in products or overlapping processes. In order to improve this, various efforts are being made, such as publishing research and reports for automating domestic mapping, but because there is no specific result, it relies on editors to make maps. This is mainly done by hand, so the time required for mapping is excessive, and quality control for each producer is different. In order to solve these problems, technology that can be automatically produced through computer programs is needed. Research has been conducted to apply the rule base to geometric generalization. The algorithm tolerance setting applied to rule-based modeling is a factor that greatly affects the result, and the level of the result changes accordingly. In this paper, we tried to study the effectiveness of mapping according to tolerance setting. To this end, the utility was verified by comparing it with a manually produced map. In addition, the original data and reduction rate were analyzed by applying generalization algorithms and tolerance values. Although there are some differences by region, it was confirmed that the complexity decreased on average. Through this, it is expected to contribute to the use of spatial information-based services by improving tolerances suitable for small-scale mapping regulations in order to secure spatial information data that guarantees consistency and accuracy.

Since 2012, the Navy has been conducting a defense experiment project to evaluate the possibility of military application by introducing new technologies related to excellent private informatization in the defense field. There are many projects that have spread because they are suitable for military use, but some have ended as experimental projects themselves because they do not meet the military s required performance. Continuous development is required as increasing the spread rate by successfully carrying out defense experiment projects is the basis for defense reform. This study analyzed the performance of major projects carried out by the Navy and presented considerations for the development of defense experiment projects to be carried out by the Navy in the future. The main achievements were derived in various ways in terms of project performance and system operation, and the considerations can be summarized in the field of raising business requirements, securing resources for system operation, determining the size of companies for project execution, and security measures. The research results can be used as data to determine the required defense experiment project and efficiently carry out the project.
