Abstract
To clarify necessary conditions when forest owner's cooperative introduces and makes use of GIS, Y forest owner's cooperative was analyzed as case study. Because Y town finished survey ownership of land, especially forest land in 1984, the land register map is precise geometrically and in content. In Y town the register about forest, such as forest owner's register, forest history register and forest map have been compiled correctly. Now that these GIS data source are precise GIS output are precise. From this it is necessary that GIS source data are correctly compiled. For introduction and practical use of GIS, following actions were needed: reaching consensus on developing GIS in cooperative, getting budget, designing system, getting good developer, driving away bugs, instructing users in GIS, directing user organization, and existing bright users. As trial and error were needed now for practical use of GIS on daily work, it is necessary that usage of GIS on daily work was developed step by step. For maintenance and renewal of GIS data, it is necessary that GIS is used daily work.
