AB - With the recent advancements in 3D GIS(Geographic Information System) technology, more realistic and precise spatial analysis has become possible. In particular, 3D GIS technology combined with digital twin technology is now widely applied in fields such as urban planning, environmental monitoring, and autonomous driving. Keeping pace with these technological developments, South Korea's V-World platform provides DEM(Digital Elevation Model) data, enhancing the potential for 3D spatial analysis by integrating it with public data. This study proposes a method to derive accurate spatial location information by combining 2D geographic coordinate data with DEM data in 3D space.
The research method involves utilizing DEM tile data to extract elevation values for specific points and employs a QuadTree structure to efficiently retrieve elevation values for multiple locations. Considering the characteristics of V-World DEM data, which provides different resolutions for each region, accuracy is improved by using the highest resolution data in each region. The effectiveness of the proposed technique is confirmed through an example of applying it to existing two-dimensional public data.
