Within recent years, enormously increasing open government data, smart devices, and location-based service requires several new approaches and solutions, incapable in the conventional geo-spatial information technology. Many endeavors in public and private sectors try to overcome the inherent deficiency of conventional Geographic Information System (GIS) by integrating Big Data and geo-spatial technology into Geo-Spatial Big Data platform. To secure technology to store, manage, analyze, and deliver service efficiently for Geo-Spatial Big Data (GSBD) with high volume in size, this study interprets GSBD platform as 7V characteristics and suggests 7V-based implementation strategy for GSBD service system. Especially, the concept and characteristics of GSBD were examined from the GSBD service perspective, based on which, a framework for GSBD service was suggested, with a plan to implement a 7V-based GSBD service system. Finally, a service scenario was set to analyze the changes in South Korea territory, with a pilot system for a GSBD service supporting it being implemented and substantiated.
