# Digital 3D Hologram Generation Using Spatial and Elevation Information
## 4 Conclusions  
This research aimed to address the limitations of previous hologram maps, which lacked thorough evaluation in terms of scale and measurement precision. To this end, we developed a hologram map integrating both 2D and 3D features. Our hologram map facilitates distance measurement and precise slope angle evaluation, crucial for detailed geographic and spatial analysis. Utilizing our map, we achieved a 3D view of areas while maintaining accuracy comparable to traditional 2D maps. This dual functionality enables users to make more informed decisions and enhances understanding of spatial environments, marking a significant advancement in mapping technology.  
Earlier efforts in hologram mapping focused primarily on 3D visualization of terrain. This study represents a pioneering effort to explore the potential for accurate distance measurement, a critical element of spatial information in maps.  
Being unprecedented in its category, our map may exhibit certain shortcomings. However, we believe this research will lay the groundwork for future studies and catalyze

further advancements in hologram mapping. Future directions could include printing this map on a 2D paper-like medium while preserving its features, potentially opening a new chapter in cartography. Additionally, the use of holographic printing techniques that allow viewing without special lighting could significantly progress the field.
